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…
Thermal Purcell effect and cavity-induced renormalization of dissipations
Giuliano Chiriacò
In recent years there has been great interest towards optical cavities as a tool to manipulate the properties and phases of embedded quantum materials. Due to the Purcell effect, a…
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…
First-order photon condensation in magnetic cavities: A two-leg ladder model
Zeno Bacciconi, Gian Marcello Andolina, Titas Chanda +3
We consider a model of free fermions in a ladder geometry coupled to a nonuniform cavity mode via Peierls substitution. Since the cavity mode generates a magnetic field, no-go theo…
Elastic stripes formation at electronic transitions
Giuliano Chiriacò, Andrew J. Millis
We investigate the possibility of a striped inhomoegenous phase occurring as an electronic system with an order parameter linearly coupled to the elastic degrees of freedom is tune…
Critical light-matter entanglement at cavity mediated phase transition
Giuliano Chiriacò, Marcello Dalmonte, Titas Chanda
We consider a model of a light-matter system, in which a system of fermions (or bosons) is coupled to a photonic mode that drives a phase transitions in the matter degrees of freed…
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…
Polarity dependent heating at the phase interface in metal-insulator transitions
Giuliano Chiriacò, Andrew Millis
Current-driven insulator-metal transitions are in many cases driven by Joule heating proportional to the square of the applied current. Recent nano-imaging experiments in CaRuO…
Negative absolute conductivity in photoexcited metals
Giuliano Chiriacò, Andrew J. Millis, Igor L. Aleiner
We show that in a model of a metal photoexcited by a transient pump pulse resonant with a phonon mode the absolute dc conductivity may become negative, depending on the interplay b…
Voltage induced metal-insulator transition in a one dimensional charge density wave
Giuliano Chiriacò, Andrew J. Millis
We present a theoretical investigation of the voltage-driven metal insulator transition based on solving coupled Boltzmann and Hartree-Fock equations to determine the insulating ga…

Giuliano Chiriacò, Andrew J. Millis, Igor L. Aleiner
Recent experiments on KC and layered copper-oxide materials have reported substantial changes in the optical response following application of an intense THz pulse. Thes…
Thermal drag in electronic conductors
Bibek Bhandari, Giuliano Chiriacò, Paolo A. Erdman +2
We study the electronic thermal drag in two different Coulomb-coupled systems, the first one composed of two Coulomb blockaded metallic islands and the second one consisting of two…
