Efficient computation of cumulant evolution and full counting statistics: application to infinite temperature quantum spin chains
Angelo Valli, Cătălin Paşcu Moca, Miklós Antal Werner +4
We propose a numerical method to efficiently compute quantum generating functions (QGF) for a wide class of observables in one-dimensional quantum systems at high temperature. We o…
Spectroscopic evidence for engineered hadron formation in repulsive fermionic Hubbard Models
Miklós Antal Werner, Cătălin Paşcu Moca, Márton Kormos +3
Particle formation represents a central theme in various branches of physics, often associated to confinement. Here we show that dynamical hadron formation can be spectroscopically…
Bloch oscillations and the lack of the decay of the false vacuum in a one-dimensional quantum spin chain
O. Pomponio, M. A. Werner, G. Zarand +1
We consider the decay of the false vacuum, realised within a quantum quench into an anti-confining regime of the Ising spin chain with a magnetic field opposite to the initial magn…
Spin fluctuations after quantum quenches in the S=1 Haldane chain: numerical validation of the semi-semiclassical theory
Miklós Antal Werner, Cătălin Paşcu Moca, Örs Legeza +2
We study quantum quenches in the Heisenberg spin chain and show that the dynamics can be described by the recently developed semi-semiclassical method based on particles prop…
On Generalized Gibbs Ensembles with an infinite set of conserved charges
B. Pozsgay, E. Vernier, M. A. Werner
We revisit the question of whether and how the steady states arising after non-equilibrium time evolution in integrable models (and in particular in the XXZ spin chain) can be desc…
Quenching the XXZ spin chain: quench action approach versus generalized Gibbs ensemble
M. Mestyan, B. Pozsgay, G. Takacs +1
Following our previous work [PRL 113 (2014) 09020] we present here a detailed comparison of the quench action approach and the predictions of the generalized Gibbs ensemble, with t…
Correlations after quantum quenches in the XXZ spin chain: Failure of the Generalized Gibbs Ensemble
B. Pozsgay, M. Mestyán, M. A. Werner +3
We study the nonequilibrium time evolution of the spin-1/2 anisotropic Heisenberg (XXZ) spin chain, with a choice of dimer product and Neel states as initial states. We investigate…
