Many-body parametric resonances in the driven sine-Gordon model
Izabella Lovas, Roberta Citro, Eugene Demler +3
We study a quantum many-body variant of the parametric oscillator, by investigating the driven sine-Gordon model with a modulated tunnel coupling via a semi-classical Truncated Wig…
Fractional corner charges in a 2D super-lattice Bose-Hubbard model
Julian Bibo, Izabella Lovas, Yizhi You +2
We study a two dimensional super-lattice Bose-Hubbard model with alternating hoppings in the limit of strong on-site interactions. We evaluate the phase diagram of the model around…
Non-local emergent hydrodynamics in a long-range quantum spin system
Alexander Schuckert, Izabella Lovas, Michael Knap
Generic short-range interacting quantum systems with a conserved quantity exhibit universal diffusive transport at late times. We employ non-equilibrium quantum field theory and se…
Non-equilibrium time evolution and rephasing in the quantum sine-Gordon model
D. X. Horvath, I. Lovas, M. Kormos +2
We discuss the non-equilibrium time evolution of the phase field in the sine-Gordon model using two very different approaches: the truncated Wigner approximation and the truncated…
Entanglement and entropy production in coupled single-mode Bose-Einstein condensates
Izabella Lovas, József Fortágh, Eugene Demler +1
We investigate the time evolution of the entanglement entropy of coupled single-mode Bose-Einstein condensates in a double well potential at temperature, by combining numeric…
Quantum correlations at infinite temperature: the dynamical Nagaoka effect
Marton Kanasz-Nagy, Izabella Lovas, Fabian Grusdt +3
Do quantum correlations play a role in high temperature dynamics of many-body systems? A common expectation is that thermal fluctuations lead to fast decoherence and make dynamics…
Full counting statistics of time of flight images
Izabella Lovas, Balázs Dóra, Eugene Demler +1
Inspired by recent advances in cold atomic systems and non-equilibrium physics, we introduce a novel characterization scheme, the time of flight full counting statistics. We benchm…
Quantum fluctuation induced time of flight correlations of an interacting trapped Bose gas
Izabella Lovas, Balázs Dóra, Eugene Demler +1
We investigate numerically the momentum correlations in a two dimensional, harmonically trapped interacting Bose system at temperature, by using a particle number preserving…
