Absence of Domain Wall Roughening in a Transverse Field Ising Model with Long-Range Interactions
George I. Mias, S. M. Girvin
We investigate roughening transitions in the context of transverse-field Ising models. As a modification of the transverse Ising model with short range interactions, which has been…
A many-fermion generalization of the Caldeira-Leggett model
Florian Marquardt, D. S. Golubev
We analyze a model system of fermions in a harmonic oscillator potential under the influence of a dissipative environment: The fermions are subject to a fluctuating force deriving…
Reentrant Phenomenon in Quantum Phase Diagram of Optical Boson Lattice
H. Kleinert, S. Schmidt, A. Pelster
We calculate the location of the quantum phase transitions of a bose gas trapped in an optical lattice as a function of effective scattering length $a_{\eff}$ and temperature .…
Evolution of the macroscopically entangled states in optical lattices
Anatoli Polkovnikov
We consider dynamics of boson condensates in finite optical lattices under a slow external perturbation which brings the system to the unstable equilibrium. It is shown that quantu…
