We review selected advances in the theoretical understanding of complex quantum many-
body systems with regard to emergent notions of quantum statistical mechanics. We cover …

We consider the time evolution of order parameter correlation functions after a sudden
quantum quench of the magnetic field in the transverse field Ising chain. Using two novel …

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 consider the stationary state properties of the reduced density matrix as well as spin–
spin correlation functions after a sudden quantum quench of the magnetic field in the …

Preparing an integrable system in a mixed state described by a thermal density matrix, we
subject it to a sudden quench and explore the subsequent unitary dynamics. To address the …

In recent years, the out-of-time-order correlator (OTOC) has emerged as a diagnostic tool for
information scrambling in quantum many-body systems. Here, we present exact analytical …

Quantum nanodevices are fundamental systems in quantum thermodynamics that have
been the subject of profound interest in recent years. Among these, quantum batteries play a …

We construct the finite-temperature dynamical phase diagram of the fully connected
transverse-field Ising model from the vantage point of two disparate concepts of dynamical …

The Loschmidt echo is a purely quantum-mechanical quantity whose determination for large
quantum many-body systems requires an exceptionally precise knowledge of all eigenstates …

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 …
