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…
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…
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…
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…
