Improved modelling of liquid GeSe: the impact of the exchange-correlation functional

M. Micoulaut, R. Vuilleumier, C. Massobrio

The structural properties of liquid GeSe are studied by using first-principles molecular dynamics in conjuncton with the Becke, Lee, Yang and Parr (BLYP) generalized gradient a…

Structural relaxation effects on interface and transport properties of Fe/MgO(001) tunnel junctions

Xiaobing Feng, O. Bengone, M. Alouani +3

The interface structure of Fe/MgO(100) magnetic tunnel junctions predicted by density functional theory (DFT) depends significantly on the choice of exchange and correlation functi…

Some Results on Cubic and Higher Order Extensions of the Poincaré Algebra

M. Rausch de Traubenberg

In these lectures we study some possible higher order (of degree greater than two) extensions of the Poincaré algebra. We first give some general properties of Lie superalgebras wi…

Phase-space structures in quantum-plasma wave turbulence

F. Haas, B. Eliasson, P. K. Shukla +1

The quasilinear theory of the Wigner-Poisson system in one spatial dimension is examined. Conservation laws and properties of the stationary solutions are determined. Quantum effec…

Semiclassical Theory of Time-Reversal Focusing

Hernan L. Calvo, Rodolfo A. Jalabert, Horacio M. Pastawski

Time reversal mirrors have been successfully implemented for various kinds of waves propagating in complex media. In particular, acoustic waves in chaotic cavities exhibit a refoca…

Accelerated kinetic Monte Carlo algorithm for diffusion limited kinetics

V. I. Tokar, H. Dreyssé

If a stochastic system during some periods of its evolution can be divided into non-interacting parts, the kinetics of each part can be simulated independently. We show that this c…

Visualizing the spin of individual molecules

C. Iacovita, M. V. Rastei, B. W. Heinrich +4

Low-temperature spin-polarized scanning tunneling microscopy is employed to study spin transport across single Cobalt-Phathalocyanine molecules adsorbed on well characterized magne…

Oersted fields and current density profiles in spin-torque driven magnetization dynamics -- Finite element modelling of realistic geometries

Riccardo Hertel

The classical impact of electrical currents on magnetic nanostructures is analyzed with numerical calculations of current-density distributions and Oersted fields in typical contac…

Persistent currents in one dimension: the other side of Leggett's theorem

Xavier Waintal, Genevieve Fleury, Kyryl Kazymyrenko +3

We discuss the sign of the persistent current of N electrons in one dimensional rings. Using a topology argument, we establish lower bounds for the free energy in the presence of a…

Loschmidt echo for local perturbations: non-monotonous cross-over from the Fermi-golden-rule to the escape-rate regime

Arseni Goussev, Daniel Waltner, Klaus Richter +1

We address the sensitivity of quantum mechanical time evolution by considering the time decay of the Loschmidt echo (LE) (or fidelity) for local perturbations of the Hamiltonian. W…

Detection of interaction-induced nonlocal effects using perfectly transmitting nanostructures

Dietmar Weinmann, Rodolfo A. Jalabert, Axel Freyn +2

We consider one-dimensional transport through an interacting region in series with a point-like one-body scatterer. When the conductance of the interacting region is perfect, indep…

Quantum plasma effects in the classical regime

G. Brodin, M. Marklund, G. Manfredi

For quantum effects to be significant in plasmas it is often assumed that the temperature over density ratio must be small. In this paper we challenge this assumption by considerin…

Fidelity decay in trapped Bose-Einstein condensates

G. Manfredi, P. -A. Hervieux

The quantum coherence of a Bose-Einstein condensate is studied using the concept of quantum fidelity (Loschmidt echo). The condensate is confined in an elongated anharmonic trap an…
