Escape-rate formalism, decay to steady states, and divergences in the entropy-production rate
Juergen Vollmer, Laszlo Matyas, Tamas Tel
In summer 1997 we were sitting with Bob Dorfman and a few other friends interested in chaotic systems and transport theory on a terrace close to Oktogon in Budapest. While taking o…
Quantum criticalities in a two-leg antiferromagnetic S=1/2 ladder induced by a staggered magnetic field
Y. -J. Wang, F. H. L. Essler, M. Fabrizio +1
We study a two-leg antiferromagnetic spin-1/2 ladder in the presence of a staggered magnetic field. We consider two parameter regimes: strong (weak) coupling along the legs and wea…
Exact Time Autocorrelation Function of the N-Spin Classical Heisenberg Equivalent Neighbor Model
Richard A. Klemm, Marco Ameduri
We reduce the autocorrelation function of the equivalent neighbor model of classical spins exhibiting Heisenberg dynamics and exchange coupling to quadrature. A…
Tunneling of quantum rotobreathers
J. Dorignac, S. Flach
We analyze the quantum properties of a system consisting of two nonlinearly coupled pendula. This non-integrable system exhibits two different symmetries: a permutational symmetry…
Dewetting of thin films on heterogeneous substrates: Pinning vs. coarsening
Lutz Brusch, Heiko Kuehne, Uwe Thiele +1
We study a model for a thin liquid film dewetting from a periodic heterogeneous substrate (template). The amplitude and periodicity of a striped template heterogeneity necessary to…
Density Matrix of a Bose--Einstein Condensate: Steady--State versus Mean--Field Approach
S. J. Wang, M. C. Nemes, A. N. Salgueiro +1
We compare the equilibrium solution for the condensate obtained in the mean--field approximation to the master equation for sympathetic cooling with the one obtained by Scully for…
