Dynamical stabilization of the bcc phase in lanthanum and thorium by phonon-phonon interaction
P. Souvatzis, T. Bjorkman, O. Eriksson +2
The recently developed self consistent {\it ab initio} lattice dynamical method (SCAILD) has been applied to the high temperature bcc phase of La and Th which are dynamically unsta…
Entropy driven stabilization of energetically unstable crystal structures explained from first principles theory
P. Souvatzis, O. Eriksson, M. I. Katsnelson +1
Conventional methods to calculate the thermodynamics of crystals evaluate the harmonic phonon spectra and therefore do not work in frequent and important situations where the cryst…
Electron self-trapping at quantum and classical critical points
M. I. Auslender, M. I. Katsnelson
Using Feynman path integral technique estimations of the ground state energy have been found for a conduction electron interacting with order parameter fluctuations near quantum cr…
Topological defects, pattern evolution, and hysteresis in thin magnetic films
P. A. Prudkovskii, A. N. Rubtsov, M. I. Katsnelson
Nature of the magnetic hysteresis for thin films is studied by the Monte-Carlo simulations. It is shown that a reconstruction of the magnetization pattern with external field occur…
