Anomalous charge transport in the sine-Gordon model
Frederik Møller, Botond C. Nagy, Márton Kormos +1
We conduct a comprehensive study of anomalous charge transport in the quantum sine--Gordon model. Employing the framework of Generalized Hydrodynamics, we compute Drude weights and…
Confinement and false vacuum decay on the Potts quantum spin chain
Octavio Pomponio, Anna Krasznai, Gábor Takács
We consider non-equilibrium dynamics after quantum quenches in the mixed-field three-state Potts quantum chain in the ferromagnetic regime. Compared to the analogous setting for th…
Sine-Gordon model at finite temperature: the method of random surfaces
M. Tóth, J. H. Pixley, D. Szász-Schagrin +2
We study the sine-Gordon quantum field theory at finite temperature by generalizing the method of random surfaces to compute the free energy and one-point functions of exponential…
Relaxation dynamics in the (double) sine-Gordon model: An open-system viewpoint
D. Szász-Schagrin, D. X. Horváth, G. Takács
We study the effects of integrability breaking on the relaxation dynamics of the (double) sine-Gordon model. Compared to previous studies, we apply an alternative viewpoint motivat…
Dynamical separation of charge and energy transport in one-dimensional Mott insulators
Frederik Møller, Botond C. Nagy, Márton Kormos +1
One-dimensional Mott insulators can be described using the sine-Gordon model, an integrable quantum field theory that provides the low-energy effective description of several one-d…
Non-equilibrium time evolution in the sine-Gordon model revisited
Dávid Szász-Schagrin, Izabella Lovas, Gábor Takács
We study the non-equilibrium dynamics of the quantum sine-Gordon model describing a pair of Josephson-coupled one-dimensional bosonic quasi-condensates. Motivated by experimentally…
