Calculating strongly correlated ground states from the non-Markovian dissipative dynamics of Gaussian fermions
Giuliano Chiriacò
We introduce a mapping between the ground state of interacting fermionic Hamiltonians and the non-equilibrium steady state of a purely dissipative open quantum system. Within the f…
Local vs global dynamics in a dissipative qubit-impurity system
Giuseppe Emanuele Chiatto, Giuliano Chiriacó, Elisabetta Paladino +1
We analyse the dynamics of a qubit coupled to a dissipative impurity by comparing local and global derivation schemes of a Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) master equat…
Entanglement transition in unitary system-bath dynamics
Bo Xing, Giuliano Chiriacò, Paola Cappellaro +2
The evolution of a system coupled to baths is commonly described by a master equation that, in the long-time limit, yields a steady-state density matrix. However, when the same evo…
Computable measures of non-Markovianity for Gaussian free fermion systems
Giuliano Chiriacò
We investigate measures of non-Markovianity in open quantum systems governed by Gaussian free fermionic dynamics. Standard indicators of non-Markovian behavior, such as the BLP and…
Dissipation and non-thermal states in cryogenic cavities
Zeno Bacciconi, Giulia Piccitto, Alessandro Maria Verga +3
We study the properties of photons in a cryogenic cavity, made by cryo-cooled mirrors surrounded by a room temperature environment. We model such a system as a multimode cavity cou…
Entanglement behavior and localization properties in monitored fermion systems
Giulia Piccitto, Giuliano Chiriacò, Davide Rossini +1
We study the asymptotic bipartite entanglement in various integrable and nonintegrable models of monitored fermions. We find that, for the integrable cases, the entanglement versus…
Entanglement enhancement induced by noise in inhomogeneously monitored systems
Cristiano Muzzi, Mikheil Tsitsishvili, Giuliano Chiriacò
We study how stronger noise can enhance the entanglement in inhomogeneously monitored quantum systems. We consider a free fermions model composed of two coupled chains - a system c…
Measurement induced transitions in non-Markovian free fermion ladders
Mikheil Tsitsishvili, Dario Poletti, Marcello Dalmonte +1
Recently there has been an intense effort to understand measurement induced transitions, but we still lack a good understanding of non-Markovian effects on these phenomena. To that…
Diagrammatic method for many-body non-Markovian dynamics: memory effects and entanglement transitions
Giuliano Chiriacò, Mikheil Tsitsishvili, Dario Poletti +2
We study the quantum dynamics of a many-body system subject to coherent evolution and coupled to a non-Markovian bath. We propose a technique to unravel the non-Markovian dynamics…
Dissipative Floquet Dynamics: from Steady State to Measurement Induced Criticality in Trapped-ion Chains
Piotr Sierant, Giuliano Chiriacò, Federica M. Surace +5
Quantum systems evolving unitarily and subject to quantum measurements exhibit various types of non-equilibrium phase transitions, arising from the competition between unitary evol…
