The effects of the pump-polarization in a degenerate pump/probe experiment are analyzed. It is shown that modulating the pump
polarization from linear to circular induces a modulation in the probe absorption change that allows to separate various contributions
that are mixed in the signal. An experimental demonstration is carried out in a laser dye (Coumarin 500).

A living polymer system is used to study the effect of concentration on a broad, polydisperse two-dimensional polymer system.
It is found that the mean squared end-to-end radius of a chain of L monomers does not decrease by following a simple power law of the concentration but by a function of the form . An origin for such a behaviour is proposed.

We calculate using diagrammatic perturbation theory in the two-loop approximation, the specific heat exponent for the classical N-vector model in a random external field for spatial dimension (D) lying between four and six. The calculation supports the modified hyperscaling , where is the correlation length exponent.

We report on observable new features related to ionization of atoms by laser pulses of only few cycles and some intensity.
We show that for particular photo-electron energies, the angular distribution becomes asymmetric and that this asymmetry is
related to the initial phase of the field.

The paper discusses the metastable states of a quantum particle in a periodic potential under a constant force (the model
of a crystal electron in a homogeneous electric field), which are known as the Wannier-Stark ladder of resonances. An efficient
procedure to find the positions and widths of resonances is suggested and illustrated by numerical calculations for a cosine
potential, which are in excellent agreement with complex scaling resonance energies.

21 /cm3. After this new ECD treatment, PS:Er was found to emit much more intense room-temperature visible photoluminescence than
both the porous silicon control and the PS:Er prepared by constant-current ECD. Room-temperature IR photoluminescence around
1.54 μm was observed for the first time without any post-doping annealing.

We reinvestigate Kreimer's Hopf algebra structure of perturbative quantum field theories with a special emphasis on overlapping
divergences. Kreimer first disentangles overlapping divergences into a linear combination of disjoint and nested ones and
then tackles that linear combination by the Hopf algebra operations. We present a formulation where the Hopf algebra operations
are directly defined on any type of divergence. We explain the precise relation to Kreimer's Hopf algebra and obtain thereby
a characterization of their primitive elements.

The effect of an electrostatic energy (in the geometrical capacitance approach) on a persistent current is considered. It
is shown that at high temperatures the current amplitude shows periodic dips as a function of the potential difference between
a ring and a reservoir. These dips correspond to a lift of the Coulomb blockade. In a minimum of a dips a current is periodic
in a magnetic flux with a period at any temperatures.

transition frequencies and the relative amplitude of resonant signals are also determined for the CH3 vibrational modes of ODT on gold.
