Far-from-equilibrium quantum dynamics

Achieving the quantum field theory limit in far-from-equilibrium quantum link models

Realizations of gauge theories in setups of quantum synthetic matter open up the possibility of probing salient exotic phenomena in condensed matter and high-energy physics, along with potential applications in quantum information and science …

Detecting quantum phase transitions in nonintegrable and long-range Ising chains using spatially minimal measurements

In a recent work [Dağ, Uhrich, and Halimeh, arXiv:2105.05986](https://arxiv.org/abs/2105.05986), single-site observables have been introduced as a versatile tool for the detection of equilibrium and dynamical criticality in short-range …

Universal equilibration dynamics of the Sachdev-Ye-Kitaev model

Equilibrium quantum many-body systems in the vicinity of phase transitions generically manifest universality. In contrast, limited knowledge has been gained on possible universal characteristics in the non-equilibrium evolution of systems in quantum …

Dynamical phase transitions in quantum spin models with antiferromagnetic long-range interactions

In recent years, dynamical phase transitions and out-of-equilibrium criticality have been at the forefront of ultracold gases and condensed matter research. Whereas universality and scaling are established topics in equilibrium quantum many-body …

Quantum quench dynamics of dipolar bosons in 2D optical lattices

We investigate the quench dynamics of the dipolar bosons in two dimensional optical lattice of square geometry using the time dependent Gutzwiller method. The system exhibits different density orders like the checkerboard and the striped pattern, …

Probing Equilibrium and Dynamical Criticality Through Single-Site Observables

Extracting critical behavior in the wake of quantum quenches has recently been at the forefront of theoretical and experimental investigations in condensed matter physics and quantum synthetic matter, with particular emphasis on experimental …

From non-Hermitian linear response to dynamical correlations and fluctuation–dissipation relations in quantum many-body systems

Quantum many-body systems are characterized by their correlations. While equal-time correlators and unequal-time commutators between operators are standard observables, the direct access to unequal-time anti-commutators poses a formidable …

Local measures of dynamical quantum phase transitions

In recent years, dynamical quantum phase transitions (DQPTs) have emerged as a useful theoretical concept to characterize nonequilibrium states of quantum matter. DQPTs are marked by singular behavior in an *effective free energy* $\lambda(t)$, …

Quantum aging and dynamical universality in the long-range $O(N\to\infty)$ model

Quantum quenches to or near criticality give rise to the phenomenon of *aging*, manifested by glassy-like dynamics at short times and far from equilibrium. The recent surge of interest in the dynamics of quantum many-body systems has rejuvenated …

Analog cosmological reheating in an ultracold Bose gas

Cosmological reheating describes the transition of the post-inflationary universe to a hot and thermal state. In order to shed light on the underlying dynamics of this process, we propose to quantum-simulate the reheating-like dynamics of a generic …
