Thermodynamics and fractal Drude weights in the sine-Gordon model
Botond C. Nagy, Márton Kormos, Gábor Takács
The sine-Gordon model is a paradigmatic quantum field theory that provides the low-energy effective description of many gapped 1D systems. Despite this fact, its complete thermodyn…
Simulating Lindbladian evolution with non-abelian symmetries: Ballistic front propagation in the Hubbard model with a localized loss
Cătălin Paşcu Moca, Miklós Antal Werner, Örs Legeza +3
We develop a non-Abelian time evolving block decimation (NA-TEBD) approach to study of open systems governed by Lindbladian time evolution, while exploiting an arbitrary number of…
Local dynamics and thermal activation in the transverse-field Ising chain
Jiahao Yang, Weishi Yuan, Takashi Imai +3
There has been considerable recent progress in identifying candidate materials for the transverse-field Ising chain (TFIC), a paradigmatic model for quantum criticality. Here, we s…
Inhomogeneous quantum quenches in the sine-Gordon theory
D. X. Horváth, M. Kormos, S. Sotiriadis +1
We study inhomogeneous quantum quenches in the attractive regime of the sine-Gordon model. In our protocol, the system is prepared in an inhomogeneous initial state in finite volum…
Cascade of singularities in the spin dynamics of a perturbed quantum critical Ising chain
Xiao Wang, Haiyuan Zou, Kristóf Hódsági +3
When the quantum critical transverse-field Ising chain is perturbed by a longitudinal field, a quantum integrable model emerges in the scaling limit with massive excitations descri…
Spectra of Quasi-one-dimensional Antiferromagnet BaCoVO under Transverse Field
Haiyuan Zou, Y. Cui, X. Wang +16
We report V nuclear magnetic resonance (NMR) and inelastic neutron scattering (INS) measurements on a quasi-1D antiferromagnet BaCoVO under transverse field alon…
