Measuring post-quench entanglement entropy through density correlations
Adrian Del Maestro, Hatem Barghathi, Bernd Rosenow
Following a sudden change of interactions in an integrable system of one-dimensional fermions, we analyze the dependence of the static structure factor on the observation time afte…
Theory of Non-Interacting Fermions and Bosons in the Canonical Ensemble
Hatem Barghathi, Jiangyong Yu, Adrian Del Maestro
We present a self-contained theory for the exact calculation of particle number counting statistics of non-interacting indistinguishable particles in the canonical ensemble. This g…
Equivalence of Spatial and Particle Entanglement Growth After a Quantum Quench
Adrian Del Maestro, Hatem Barghathi, Bernd Rosenow
We analyze fermions after an interaction quantum quench in one spatial dimension and study the growth of the steady state entanglement entropy density under either a spatial mode o…
Extinction phase transitions in a model of ecological and evolutionary dynamics
Hatem Barghathi, Skye Tackkett, Thomas Vojta
We study the non-equilibrium phase transition between survival and extinction of spatially extended biological populations using an agent-based model. We especially focus on the ef…
Contact process with temporal disorder
Hatem Barghathi, Jose A. Hoyos, Thomas Vojta
We investigate the influence of time-varying environmental noise, i.e., temporal disorder, on the nonequilibrium phase transition of the contact process. Combining a real-time reno…
Random field disorder at an absorbing state transition in one and two dimensions
Hatem Barghathi, Thomas Vojta
We investigate the behavior of nonequilibrium phase transitions under the influence of disorder that locally breaks the symmetry between two symmetrical macroscopic absorbing state…
Enhanced rare region effects in the contact process with long-range correlated disorder
Ahmed K. Ibrahim, Hatem Barghathi, Thomas Vojta
We investigate the nonequilibrium phase transition in the disordered contact process in the presence of long-range spatial disorder correlations. These correlations greatly increas…
Contact process on generalized Fibonacci chains: infinite-modulation criticality and double-log periodic oscillations
Hatem Barghathi, David Nozadze, Thomas Vojta
We study the nonequilibrium phase transition of the contact process with aperiodic transition rates using a real-space renormalization group as well as Monte-Carlo simulations. The…
Random fields at a nonequilibrium phase transition
Hatem Barghathi, Thomas Vojta
We investigate nonequilibrium phase transitions in the presence of disorder that locally breaks the symmetry between two equivalent macroscopic states. In low-dimensional equilibri…
Infinite-randomness criticality in a randomly layered Heisenberg magnet
Fawaz Hrahsheh, Hatem Barghathi, Thomas Vojta
We study the ferromagnetic phase transition in a randomly layered Heisenberg magnet using large-scale Monte-Carlo simulations. Our results provide numerical evidence for the infini…
