We review recent theoretical work on two closely related issues: excitation of an isolated
quantum condensed matter system driven adiabatically across a continuous quantum phase …

The transverse field Ising and XY models (the simplest quantum spin models) provide the
organising principle for the rich variety of interconnected subjects which are covered in this …

This short review explores the physics journey of Professor Amit Dutta, illuminating his
collaborative contributions with students and peers. We mainly focus on standard …

We explore the nonequilibrium response of Chern insulators. Focusing on the Haldane
model, we study the dynamics induced by quantum quenches between topological and …

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 quenching dynamics of a one-dimensional transverse Ising chain with nearest
neighbor antiferromagnetic interactions in the presence of a longitudinal field which renders …

When a system is driven across a quantum critical point at a constant rate, its evolution must
become nonadiabatic as the relaxation time τ diverges at the critical point. According to the …

We discuss the quench dynamics near a quantum critical point focusing on the sine-Gordon
model as a primary example. We suggest a unified approach to sudden and slow quenches …

The discovery of nonlocal order parameters in real space provides a feasible scheme for
studying dynamical critical behavior in topological systems. We study the critical phenomena …

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 …
