Fast electronic relaxation in metal nanoclusters via excitation of coherent shape deformations: Circumventing a bottleneck
Vitaly V. Kresin, Yu. N. Ovchinnikov
Electron-phonon relaxation in size-quantized systems may become inhibited when the spacing of discrete electron energy levels exceeds the magnitude of the phonon frequency. We show…
Effect of nuclear quadrupole interactions on the dynamics of two-level systems in glasses
A. L. Burin, I. Ya. Polishchuk, P. Fulde +1
The standard tunneling model describes quite satisfactorily the thermal properties of amorphous solids at temperatures in terms of an ensemble of two-level systems possessin…
Multi-peaked localized states of DNLS in one and two dimensions
G. Kalosakas
Multi-peaked localized stationary solutions of the discrete nonlinear Schrodinger (DNLS) equation are presented in one (1D) and two (2D) dimensions. These are excited states of the…
Interplay between Zeeman interaction and spin-orbit coupling in a two-dimensional semiconductor system
Manuel Valin-Rodriguez, Rashid G. Nazmitdinov
We analyse the interplay between Dresselhaus, Bychkov-Rashba, and Zeeman interactions in a two-dimensional semiconductor quantum system under the action of a magnetic field. When a…

C. H. Choi, A. Usheva, G. Kalosakas +2
Comment on T.S. van Erp, S. Cuesta-Lopez, J.-G. Hagmann, and M. Peyrard, Phys. Rev. Lett. 95, 218104 (2005) [arXiv: physics/0508094].
Frozen local hole approximation
Elke Pahl, Uwe Birkenheuer
The frozen local hole approximation (FLHA) is an adiabatic approximation which is aimed to simplify the correlation calculations of valence and conduction bands of solids and polym…
Scattering length for helium atom-diatom collision
Elena A. Kolganova, Alexander K. Motovilov, Werner Sandhas
We present results on the scattering lengths of ^4He--^4He_2 and ^3He--^4He_2 collisions. We also study the consequence of varying the coupling constant of the atom-atom interactio…
Polyatomic Molecules Formed with a Rydberg Atom in an Ultracold Environment
Ivan C. H. Liu, Jan M. Rost
We investigate properties of ultralong-range polyatomic molecules formed with a Rb Rydberg atom and several ground-state atoms whose distance from the Rydberg atom is of the order…
Universal behavior in populations composed of excitable and self-oscillatory elements
Diego Pazó, Ernest Montbrió
We study the robustness of self-sustained oscillatory activity in a globally coupled ensemble of excitable and oscillatory units. The critical balance to achieve collective self-su…
Spin waves in a band ferromagnet: spin-rotationally symmetric study with self-energy and vertex corrections
Avinash Singh
First-order quantum corrections to the transverse spin-fluctuation propagator are obtained within a systematic inverse-degeneracy 1/N expansion, which provides a spin-rotationally…
Driven diffusive systems of active filament bundles
P. K. Mohanty, K. Kruse
The cytoskeleton is an important subsystem of cells that is involved for example in cell division and locomotion. It consists of filaments that are cross-linked by molecular motors…
Transport in chaotic quantum dots: effects of spatial symmetries which interchange the leads
Victor A. Gopar, Stefan Rotter, Henning Schomerus
We investigate the effect of spatial symmetries on phase coherent electronic transport through chaotic quantum dots. For systems which have a spatial symmetry that interchanges the…
Soliton ratchets in homogeneous nonlinear Klein-Gordon systems
Luis Morales-Molina, Niurka R. Quintero, Franz G. Mertens +1
We study in detail the ratchet-like dynamics of topological solitons in homogeneous nonlinear Klein-Gordon systems driven by a bi-harmonic force. By using a collective coordinate a…
A simplified method for the computation of correlation effects on the band structure of semiconductors
Uwe Birkenheuer, Peter Fulde, Hermann Stoll
We present a simplified computational scheme in order to calculate the effects of electron correlations on the energy bands of diamond and silicon. By adopting a quasiparticle pict…
Simulating nanoscale dielectric response
A. C. Maggs, R. Everaers
We introduce a constrained energy functional to describe dielectric response. We demonstrate that the local functional is a generalization of the long ranged Marcus energy. Our re-…

Mario De Menech, Ulf Saalmann, Martin E. Garcia
We present a detailed theoretical study of scanning tunneling imaging and spectroscopy of \Csixty on silver and gold surfaces, motivated by the recent experiments and discussion by…
Field-induced Bose-Einstein condensation of interacting dilute magnons in three-dimensional spin systems: A renormalization-group study
M. Crisan, I. Tifrea, D Bodea +1
We use the Renormalization Group method to study the magnetic field influence on the Bose-Einstein condensation of interacting dilute magnons in three dimensional spin systems. We…
Modeling of droplet breakup in a microfluidic T--shaped junction with a phase--field model
Mario De Menech
A phase--field method is applied to the modeling of flow and breakup of droplets in a T--shaped junction in the hydrodynamic regime where capillary and viscous stresses dominate ov…
Ginzburg-Landau theory of superconducting surfaces under electric fields
P. Lipavsky, K. Morawetz, J. Kolacek +1
A boundary condition for the Ginzburg-Landau wave function at surfaces biased by a strong electric field is derived within the de Gennes approach. This condition provides a simple…
