Lecture Notes on Quantum Many-Body Theory: A Pedagogical Introduction
Fabrizio Tafuri, Carmine Antonio Perroni, Giulio De Filippis
In these notes, we present a rigorous and self-contained introduction to the fundamental concepts and methods of quantum many-body theory. The text is designed to provide a solid t…
Geometry and restoration of the quantum Mpemba effect beyond weak-coupling regime in the spin-boson model
P. Chirico, G. Di Bello, G. De Filippis +1
Understanding relaxation dynamics in open quantum systems is a central problem in nonequilibrium quantum physics. Here we investigate the quantum Mpemba effect in the spin-boson mo…
Kibble-Zurek Mechanism in the Open Quantum Rabi Model
T. Pirozzi, G. Di Bello, V. Cataudella +2
The Kibble-Zurek mechanism provides a universal framework for predicting defect formation in non-equilibrium phase transitions. While Markovian dissipation typically degrades unive…
Quantum Brownian Motion: proving that the Schmid transition belongs to the Berezinskii-Kosterlitz-Thouless universality class
Francesco G. Capone, Antonio de Candia, Vittorio Cataudella +4
We investigate the equilibrium properties of a quantum Brownian particle moving in a periodic potential, specifically addressing the nature of the dissipation-driven Schmid transit…
Inhomogeneous superconductivity in (001), (110), and (111) KTaO two-dimensional electronic gases: effect of electronic confinement on the transition temperature
Mattia Trama, Matta Trama, Roberta Citro +1
Experimental observations on KTaO superconductivity report widely different critical temperatures with a clear hierarchy among different crystallographic orientations. Accounti…
Spin Hall and Edelstein effects in a ballistic quantum dot with Rashba spin-orbit coupling
Alfonso Maiellaro, Francesco Romeo, Mattia Trama +11
We study spin-resolved transport in a ballistic quantum dot with Rashba spin-orbit coupling, focusing on charge-to-spin conversion and spin Hall effect. In the regime where the dot…
