The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

In this review, after providing the basic physical concept behind quantum annealing (or
adiabatic quantum computation), we present an overview of some recent theoretical as well …

The many-body physics at quantum phase transitions shows a subtle interplay between
quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we …

The number of topological defects created in a system driven through a quantum phase
transition exhibits a power-law scaling with the driving time. This universal scaling law is the …

Phase transitions represent a compelling tool for classical and quantum sensing
applications. It has been demonstrated that quantum sensors can in principle saturate the …

We review the effects of excited-state quantum phase transitions (ESQPTs) in interacting
many-body systems with finite numbers of collective degrees of freedom. We classify typical …

Quantum metrology refers to the use of quantum resources in parameter-estimation
protocols, aiming at enhancing its precision. The quantum Fisher information is a key …

We propose that a broad class of excited-state quantum phase transitions (ESQPTs) gives
rise to two different excited-state quantum phases. These phases are identified by means of …

Phase transitions have recently been formulated in the time domain of quantum many-body
systems, a phenomenon dubbed dynamical quantum phase transitions (DPTs), whose …

We study the quantum dynamics of many-body systems, in the presence of dissipation due
to the interaction with the environment, under Kibble-Zurek (KZ) protocols in which one …
