  author={Souvik Bandyopadhyay and Anatoli Polkovnikov and Amit Kumar Dutta},
In recent times it has been observed that signatures of equilibrium quantum criticality surprisingly show up in many-body systems which are manifestly far from equilibrium. We explore such scenarios in interacting spin systems subject to a quench and develop a robust method to systematically probe ground state critical physics through nonequilibrium post-quench dynamics. Analyzing late-time behavior of finite string-like observables, we find emerging sharp signatures of equilibrium criticality… 



Signatures of Quantum Phase Transitions after Quenches in Quantum Chaotic One-Dimensional Systems

Quantum phase transitions are central for the understanding of the equilibrium low-temperature properties of quantum matter. Locating them can be challenging both by means of theoretical techniques

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

Nonequilibrium Criticality in Quench Dynamics of Long-Range Spin Models.

A prototype of infinite-range interacting models known as the Lipkin-Meshkov-Glick model is considered describing the collective interaction of N spins and the dynamical properties of fluctuations and correlations after a sudden quench of the Hamiltonian are investigated.

Dynamics after quenches in one-dimensional quantum Ising-like systems

We study the out-of-equilibrium dynamics of one-dimensional quantum Ising-like systems, arising from sudden quenches of the Hamiltonian parameter $g$ driving quantum transitions between disordered

Probing Ground-State Phase Transitions through Quench Dynamics.

It is demonstrated that this method can be used to approximately locate the quantum critical point near integrability and the continued existence of a dynamical critical point detectable at prethermal timescales is demonstrated.

Determination of Dynamical Quantum Phase Transitions in Strongly Correlated Many-Body Systems Using Loschmidt Cumulants

Dynamical phase transitions extend the notion of criticality to non-stationary settings and are characterized by sudden changes in the macroscopic properties of time-evolving quantum systems.

Dynamical phase transitions after quenches in nonintegrable models

We investigate the dynamics following sudden quenches across quantum critical points belonging to different universality classes. Specifically, we use matrix product state methods to study the

Unconventional critical exponents at dynamical quantum phase transitions in a random Ising chain

Dynamical quantum phase transitions (DQPTs) feature singular temporal behavior in transient quantum states during nonequilibrium real-time evolution. In this work we show that DQPTs in random Ising

Finding the phase diagram of strongly correlated disordered bosons using quantum quenches

The question of how the low-energy properties of disordered quantum systems may be connected to exotic localization phenomena at high energy is a key open question in the context of quantum glasses
