Active Quantum Particles from Engineered Dissipation
Jeanne Gipouloux, Matteo Brunelli, Leticia Cugliandolo +2
We introduce and characterize different models for an active quantum particle where activity arises from engineered dissipation-- specifically, from a suitably coupled nonequilibri…
Dissipative phase transition of interacting non-reciprocal fermions
Rafael D. Soares, Matteo Brunelli, Marco Schirò
While non-reciprocal couplings are ubiquitous in classical systems, their impact on quantum many-body criticality and entanglement remains largely unexplored. Using exact numerical…
Replica Field Theory of Quantum Jumps Monitoring: Application to the Ising Chain
Youenn Le Gal, Marco Schirò
In this work we derive the replica field theory for monitored quantum many-body systems evolving under the quantum jumps protocol, corresponding to a non-Hermitian evolution inters…
Non-Stabilizerness of Sachdev-Ye-Kitaev Model
Surajit Bera, Marco Schirò
We study the non-stabilizerness or quantum magic of the Sachdev-Ye-Kitaev () model, a prototype example of maximally chaotic quantum matter. We show that the Majorana spec…
Time-dependent Variational Principles for Hybrid Non-Unitary Dynamics: Application to Driven-Dissipative Superconductors
Pasquale Filice, Marco Schirò, Giacomo Mazza
We introduce time-dependent variational principles to study the non-unitary dynamics of open quantum many-body systems, including dynamics described by the full Lindblad master equ…
Many-Body Open Quantum Systems
Rosario Fazio, Jonathan Keeling, Leonardo Mazza +1
These Lecture Notes discuss the recent theoretical advances in the understanding of open quantum many-body physics in platforms where both dissipative and coherent processes can be…
