Decoherence and relaxation of topological states in extended quantum Ising models
Hannes Weisbrich, Wolfgang Belzig, Gianluca Rastelli
We study the decoherence and the relaxation dynamics of topological states in an extended class of quantum Ising chains which can present a manyfold ground state subspace. The lead…
Decoherence in the quantum Ising model with transverse dissipative interaction in the strong coupling regime
Hannes Weisbrich, C. Saussol, Wolfgang Belzig +1
We study the decoherence dynamics of a quantum Ising lattice of finite size with a transverse dissipative interaction, namely the coupling with the bath is assumed perpendicular to…
Optical and spectral properties of quantum domain-walls in the generalized Wigner lattice
S. Fratini, G. Rastelli
We study the spectral properties of a system of electrons interacting through long-range Coulomb potential on a one-dimensional chain. When the interactions dominate over the elect…
Wigner crystallization in a polarizable medium
G. Rastelli, S. Ciuchi
We present a variational study of the 2D and 3D Wigner crystal phase of large polarons. The method generalizes that introduced by S. Fratini,P.\ Qu{é}merais [Mod. Phys. Lett. B {\b…
