We study the slow quenching dynamics (characterized by an inverse rate τ− 1) of a one-
dimensional transverse Ising chain with nearest neighbor ferromagentic interactions across …

We study an integrable spin chain with three spin interactions and the staggered field (λ)
while the latter is quenched either slowly [in a linear fashion in time (t) as t/τ, where t goes …

We study if the interplay between dynamical localization and interactions in periodically
driven quantum systems can give rise to anomalous thermalization behavior. Specifically …

We study the fractional boundary charges (FBCs) occurring in nanowires in the presence of
periodically modulated chemical potentials and connect them to the FBCs occurring in a two …

We consider the one-dimensional XX model in a quasiperiodic transverse field described by
the Harper potential, which is equivalent to a tight-binding model of spinless fermions with a …

We review quantum phase transitions of spin systems in transverse magnetic fields taking
the examples of the spin-1/2 Ising and XY models in a transverse field. Beginning with an …

Recently it has been shown that the fidelity of the ground state of a quantum many-body
system can be used to detect its quantum critical points (QCPs). If g denotes the parameter …

We study nonequilibrium dynamics of the quantum Ising chain at zero temperature when the
transverse field is varied stochastically. In the equivalent fermion representation, the …

Non-equilibrium relaxation in a closed quantum system following a change of some
parameter (s) in the Hamiltonian is of recent interest, both experimentally and theoretically …
