Probing nonequilibrium transport and density profiles in tilted interacting fermion chains with local reservoirs

Andrea Nava, N. Aucar Boidi, Reinhold Egger +2

We investigate how local particle reservoirs can probe transport and density profiles in tilted spinless fermion chains with nearest-neighbor interactions. Using finite-chain Lindb…

Exponential Speedup of Entanglement Generation by Quantum Mpemba Effects

Sara M. Benjadi, Reinhold Egger, Igor Gornyi +1

Entanglement is a key resource for quantum technologies. We show that protocols employing quantum Mpemba effects allow one to exponentially accelerate the generation of entanglemen…

Dissipation Mechanisms and Dissipative Phase Transitions of two coupled Fully Connected Quantum Ising models

Bidyut Dey, Andrea Nava, Domenico Giuliano

We study dissipative phase transitions in a system of two coupled fully-connected quantum Ising models interacting with an environment. The dynamics is governed by a Lindblad maste…

Optimal speed-up of multi-step Pontus-Mpemba protocols

Marco Peluso, Reinhold Egger, Andrea Nava

The classical Mpemba effect is the counterintuitive phenomenon where hotter water freezes faster than colder water due to the breakdown of Newton's law of cooling after a sudden te…

Information transport and transport-induced entanglement in open fermion chains

Andrea Nava, Claudia Artiaco, Yuval Gefen +4

Understanding the entanglement dynamics in quantum many-body systems under steady-state transport conditions is an actively pursued challenging topic. Hydrodynamic equations, akin…

Post-quench relaxation dynamics of Gross-Neveu lattice fermions

Domenico Giuliano, Reinhold Egger, Bidyut Dey +1

We study the quantum relaxation dynamics for a lattice version of the one-dimensional (1D) -flavor Gross-Neveu (GN) model after a Hamiltonian parameter quench. Allowing for a sy…

Speeding up Pontus-Mpemba effects via dynamical phase transitions

Andrea Nava, Reinhold Egger, Bidyut Dey +1

We demonstrate that open quantum systems exhibiting dynamical phase transitions (DPTs) allow for efficient protocols implementing the Pontus-Mpemba effect. The relaxation speed-up…

Pontus-Mpemba effects

Andrea Nava, Reinhold Egger

Mpemba effects occur after a sudden quench of control parameters if for ''far'' (or ''hot'') initial states with respect to a final target state, the relaxation time toward the tar…

Green's Function Approach to Josephson Dot Dynamics and Application to Quantum Mpemba Effects

Kateryna Zatsarynna, Andrea Nava, Reinhold Egger +1

We develop a Green's function approach for the nonequilibrium dynamics of multi-level quantum dots coupled to multiple fermionic reservoirs in the presence of a bosonic environment…

Numerical Study of Disordered Noninteracting Chains Coupled to a Local Lindblad Bath

Viktor Berger, Andrea Nava, Jens H. Bardarson +1

Disorder can prevent many-body quantum systems from reaching thermal equilibrium, leading to a many-body localized phase. Recent works suggest that nonperturbative effects caused b…

Mpemba effects in open nonequilibrium quantum systems

Andrea Nava, Reinhold Egger

We generalize the classical thermal Mpemba effect (where an initially hot system relaxes faster to the final equilibrium state than a cold one) to open quantum systems coupled to s…

Many-body quantum dynamics of spin-orbit coupled Andreev states in a Zeeman field

Kateryna Zatsarynna, Andrea Nava, Alex Zazunov +1

We provide a theoretical framework to describe the quantum many-body dynamics of Andreev states in Josephson junctions with spin-orbit coupling and a magnetic Zeeman field. In such…
