Some magnetic properties of ferromagnetoelectric nickel iodine boracite

Synthetic and very pure single crystals of nickel iodine boracite up to 10 mm in their largest dimensions were grown by a chemical transport process and investigated using a selfcompensating recording torsion balance. Below 60°K ferromagnetic behaviour was observed. In the (100) plane large tetragonal torsion moments having frequent discontinuities were observed.Part of this paper was presented at the International Conference on Magnetism, September 10–16, 1967 Boston, USA.     

Fiber Optics: Physics and Technology,by Fedor Mitschke

This Conference, under the auspices of OEEC and the International Union of Pure and Applied Physics, was attended by more than a hundred delegates, representing some twenty-six nations. The Conference Chairman was Professor Sanborn C. Brown (U.S.A.), and the Conference Secretary Mr. Norman Clarke. The forty papers to be discused had been circulated to delegates well before the Conference, and the actual sessions were devoted to general discussions based on groups of papers which formed a unifying theme. Immediately after the close of the Conference, Prof. Brown and Mr. Clarke began the preparation of a full report of the proceedings, which will make a substantial volume. Among the general topics discussed were the place of physics in general education (opened by Mr. Clarke); the selection of university entrants for physics courses (Prof. G. K. T. Conn); examinations in physics (Dr. H. F. Boulind); the use of films and television in physics teaching (Dr. Harvey White, U.S.A.); and the Physical Science Study Committee's syllabus and programme (Prof. J. R. Zacharias, U.S.A.).     

Tails and Ties

The study of behavioural and social phenomena has experienced a surge of interest over the last decade. One reason for this great attention is the huge amount of high quality data made available by the internet technologies. The many studies spanning concepts and problems belonging to economics, biology, ecology, physics and computer science, clearly indicates increasing interdisciplinary cross-fertilization, commonalities in the different approaches and communication across these disciplines. This issue of The European Physical Journal B is devoted to the interdisciplinary field of Sociophysics. The papers have been selected from the contributions presented at the 5th International Conference on “Applications of Physics in Financial Analysis" (APFA5) held in Torino from June 29th to July 1st 2006 (http://www.polito.it/apfa5). The synergy and richness of results obtained from the investigation of problems belonging to the area of complexity science from different perspectives clearly indicates future directions and research methodologies in this field.     

Preface

<正>The 5-th International Conference on Quarks and Nuclear Physics (QNP09) was held at the Institute of High Energy Physics (IHEP) of Chinese Academy of Sciences,in Beijing,China,from September 21 to 25,2009.The scientific contents of the QNP series are broad,covering developments in non-perturbative QCD     

Where do we stand on econophysics?

This issue contains papers selected from the contributions presented at the 5th International Conference on “Applications of Physics in Financial Analysis” (APFA5) held in Torino from June 29th to July 1st, 2006 (http://www.polito.it/apfa5). The issue collects recent applications of models and methods of statistical physics to economic problems. This interdisciplinary field of research, known as Econophysics, has seen intensive growth over the last decade. The challenge for econophysicists will be to go beyond the traditional views of economics and physics unifying the separate lines of development followed by the two disciplines over great part of the 20th century.“The conventional view serves to protect us from the painful job of thinking”, John Kenneth Galbraith (1908-2006).     

The Okorokov effect: Features of current experimental and theoretical studies; prospects of application

VUVX2010: 37th International Conference on Vacuum Ultraviolet and X-ray Physics

UVX2010, the 37^th International Conference on Vacuum Ultraviolet and X-ray Physics, took place from July 11-16, 2010, on the campus of the University of British Columbia (UBC). This meeting was the first of the merged Vacuum Ultraviolet Radiation Physics and X-ray and Inner Shell Processes conference series. The immediate preceding conferences were VUV15 (Berlin, 2007), and X-08 (Paris, 2008). VUVX2010 brought together scientists from countries all over the world working with synchrotron-, laser-, and plasma-based sources of electromagnetic radiation in the vacuum ultraviolet (VUV), soft X-ray, and hard X-ray regions, and developing novel applications of these sources in a variety of fields. Topics presented ranged from basic physics to materials science and technology, from molecular reactions to the characterization of catalysts under working conditions, from biology to medical diagnostics, from metrology to the development of advanced synchrotron and optical instrumentation. There were over 500 oral and poster presentations, with 480 attendees from 29 different countries. This conference took place on the fiftieth anniversary of the invention of the laser and in the year following the first operation of the Linear Coherent Light Source (LCLS), the world's first accelerator-based X-ray laser. It brought together the global community of VUV and X-ray scientists who use synchrotron-, laser-, and plasma-based sources of vacuum ultraviolet, soft X-ray, and hard X-ray light to explore new phenomena and to develop a better understanding of the physics of the interaction of light and matter.

The nature of the superconducting state of the high-T c superconductors

At the present time it is possible to get a reasonably good understanding of the nature of the superconducting state in the recently discovered, high transition temperature cuprate superconductors based on experimental results published over the past year or two. These experiments now impose significant constraints on possible theoretical models which can be used to explain the superconductivity. We show how these experiments impose these constraints and discuss those questions which remain unanswered.Invited talk at the International Conference on Macroscopic Quantum Phenomen a, Smolenice Castle, Czechoslovakia, September 18–22, 1989.I am indebted to J. P. Collman, C. Caley, M. Holcomb, and G. Yee for valuable discussion, comments and criticism.

Performance of the insertion device NEG‐coated aluminum vacuum chamber at ELETTRA

The university town of Camerino in central Italy hosted the Fourteenth International Conference on X-ray Absorption Fine Structure (XAFS-14) in July 2009. This historical town, surrounded by the rolling hills and beautiful countryside of the Marche region, was an ideal location for a stimulating conference, providing an optimal mix of good infrastructure for the meeting spaces with a feeling of remoteness from routine much appreciated by participants. Low registration fees, especially for students, resulted in a high attendance of about 500 participants. The XAFS conferences are organized by the International X-ray Absorption Society (IXAS, http://www.ixasportal.net/ixas) and this edition's chairman was A. Di Cicco, with A. Filipponi acting as co-chair.     

Algebraic approaches in nuclear physics

In these lectures I discuss algebraic approaches in nuclear physics. The emphasis is on aspects that can not be found in the same form in other publications of the subject. We discuss the relation between bosons and fermions, as well as some of the standard formalism underlying all algebraic models in nuclear physics. We then contrast fermionic and bosonic models. We end with a case study on supersymmetry in superdeformed nuclei. Dedicated to the memory of Prof. P.W.M. Glaudemans, 1931–1998. Lecture given at the 10th Indian-Summer School of Nuclear Physics: “Theory of Many-Fermion Systems”, Prague, September 8–12, 1997.     

An introduction to covariant superstring field theories

A pedagogical account is given of the recent developments in covariant (super)string field theories. After reviewing the construction of the free open bosonic string field theory, the super-symmetric case is treated and the space-time supersymmetry transformations are explained. The present status and some future problems are also summarized.Invited talk presented at the International Conference Selected Topics in Quantum Field Theory and Mathematical Physics, Bechyn, Czechoslovakia, June 23–27, 1986.On leave of absence fromNational Laboratory for High Energy Physics (KEK), Tsukuba, Ibaraki, Japan.I would like to thank A.

Quantum interference and cryptographic keys: novel physics and advancing technologies (QUICK)

This special issue of The European Physical Journal - D was organised in conjunction with the conference “Quantum interference and cryptographic keys: novel physics and advancing technologies (QUICK)", that took place in the Institut d'études Scientifiques de Cargèse from April 7th to 13th, 2001. This conference was organised at the initiative of the European Quantum Communication and Cryptography projects QuComm, S4P, QuiCoV, EQUIS and EQCSPOT, in the framework of the European Union IST/FET/QIPC program. The conference successfully achieved its goal which was to provide a forum for scientific exchanges for one hundred researchers and students, from academia and industry, working world-wide on the physics, implementations, and applications of quantum communications. The papers in this special issue give an account of some highlights of the conference. They were selected and refereed according to the high quality scientific standards of the European Physical Journal and include topics of the highest contemporary interest in the field, such as practical implementations and security proofs of Quantum Key Distribution, single photon sources, new schemes involving quantum continuous variables and the manipulation of non-classical light. We acknowledge the support given by the European Commission (High Level Scientific Conference), QUIPROCONE (Network of Excellence), the Centre National de la Recherche Scientifique, the Délégation Générale pour l'Armement (DGA), the U.S. Army Research Laboratory (European Research Office) and the USAF European Office of Aerospace Research and Development. We hope this issue will remind all participants of the special atmosphere of creative work and co-operation of the conference, and will give the general readership of EPJ D a feeling for the character of this attractive field of research. Finally, we warmly thank the Cargèse team and the EPJ D Editorial Office for their efficient and friendly help with all organisational issues. Philippe Grangier, John Rarity, Anders Karlsson     

Sinn und Möglichkeiten der Theoretischen Physik. Zum 300. Jahrestag von Newtons „Philosophiae Naturalis Principia Mathematica”︁

The Meaning and Abilities of Theoretical Physics The Newtonean principles and — derived from them — the congnition of the exixtence of elementary constants according to Planck, Einstein and Bohr increasingly prove to be a strong base not only of physics and its apllication in technology but also of each kind of “exact” sciences in the broadest sense of the word. Since Newton the clarification of concepts with regard so their physical takes place in close connection with the development of mathematical methods. This combination proves to be further productive and ensures the progress of physics an of the “exact” sciences. Most likely all problems which may be of importance in the realm of life can be treated successfully — adequate expenditure taken for granted — with the existing fund of knowledge and methods. The connection between law and accident resting on reality proves to be a relation of complementarity (“there is no absolute accident”). This becomes evident in all branches in all branches of physics, not only in thermodynamics and quantum physics, and can be treated already on the level of the Newtonean principles and elementary constants. Theoretical physics as initiated by newton was designed to comprise all parts of nature. About that there is no contrast between classical physics and quantum physics. It is only a matter of differentiation with regard to the different physical contents and the appropriate mathematical methods, dependent of course on the choice problems. Theoretical physics represents a generally available concentration of the reliable knowledge of physics, which is at the same time the foundation of the “exact” sciences. In this way theoretical physics is the means of communication within the cooperation necessary for the solution of the great complex tasks of science and technology.
