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…
Symmetries, Conservation Laws and Entanglement in Non-Hermitian Fermionic Lattices
Rafael D. Soares, Youenn Le Gal, Chun Y. Leung +3
Non-Hermitian quantum many-body systems feature steady-state entanglement transitions driven by the competition between unitary dynamics and dissipation. In this work, we reveal th…
Entanglement growth in the dark intervals of a locally monitored free-fermion chain
Giovanni Di Fresco, Youenn Le Gal, Davide Valenti +3
We consider a free fermionic chain with monitoring of the particle density on a single site of the chain and study the entanglement dynamics of quantum jump trajectories. We show t…
Entanglement Transition due to particle losses in a monitored fermionic chain
Rafael D. Soares, Youenn Le Gal, Marco Schirò
Recently, there has been interest in the dynamics of monitored quantum systems using linear jump operators related to the creation or annihilation of particles. Here, we study the…
