Our understanding of how photons couple to different degrees of freedom in solids forms the bedrock of ultrafast physics and materials sciences. In this review, the emergent ultrafast dynamics in condensed matter at the attosecond timescale have been intensively discussed. In particular, the focus is put on recent developments of attosecond dynamics of charge, exciton, and magnetism. New concepts and indispensable role of interactions among multiple degrees of freedom in solids are highlighted. ... 相似文献

The stochastic variational method is a powerful approach to solve few-body problems. The application of the stochastic variational approach to few-body problems in condensed matter physics is presented. The examples include calculation of energy spectra of atoms in magnetic field, confined atoms and trapped Fermi gases. 相似文献

Recent developments in the study of nonlinear phenomena have led to the realization that a combination of the concepts of
integrability, geometry and topology provides a new powerful framework for describing a great variety of physical systems.
It was therefore felt that the compilation of a special issue comprising articles on the interdiseiplinary topic of Geometry,
Integrability and Nonlinearity in Condensed Matter Physics, would indeed be timely. The enthusiastic response and support
that we received from the active researchers in this subject, when we organized an International Conference on the above topic
from July 15 to July 20, 2001, in Bansko, Bulgaria, provided a further motivation for undertaking this task.
As the topic is interdisciplinary in nature, the articles in this volume contain new results on a wide range of subjects.
These include among others, integrable equations and the interplay between geometry and nonlinearity, the role of optical
solitons in communication. (and, possibly, computation), common nonlinear and geometrical aspects of condensed matter, field
theory, and so on. The increasingly important role played by geometry and topology in diverse areas such as the quantum Hall
effect, localization, deformation and elasticity, quasiparticle kinetics and dynamics, spin systems, membranes, is highlighted
in some of the articles. There are papers in which essential links of nonlinearity to differential geometry are identified
and many elegant mathematical methods are presented. Some other articles focus on how the mathematical tools of geometry and
nonlinear analysis can be applied to solve certain physical problems.
Given the vast range of titles, it was difficult to strictly divide the contributions into distinct categories. Except for
the pedagogical introductory article by Rajaraman titled "CP
N
Solitons in Quantum Hall Systems", which essentially "sets the stage" for the various themes covered, we have grouped the
articles broadly under the following headings: Geometry, integrability and mathematical physics; Solitons: Interaction phenomena,
nonlinear optics; Condensed matter physics; Soft condensed matter physics; Quantum phenomena.
We gratefully acknowledge the support from Los Alamos National Lab, USA; Université de Cergy-Pontoise, France; The Abdus Salam
International Centre for Theoretical Physics, Trieste, Italy and the Institute for Nuclear Research and Nuclear Energy, Sofia,
Bulgaria, in putting this special volume together. We believe that the cross-fertilization and synergy of a host of ideas
in seemingly disparate fields of physics would lead to the natural emergence of new paradigms, which in turn could pave the
way for collaborative research to arrive at new solutions of complex nonlinear problems. It is our hope that this topical
issue will be useful in providing an impetus for achieving this broad objective.
