The quantum Mpemba effect in symmetric random Clifford circuits

Shion Yamashika, Filiberto Ares, Pasquale Calabrese

The quantum Mpemba effect is the counterintuitive phenomenon whereby a quantum state initially farther from equilibrium relaxes faster than one initially closer to it. We demonstra…

Entanglement asymmetry and quantum Mpemba effect for Kramers-Wannier duality

Milo Vescovo, Pasquale Calabrese, Filiberto Ares

The Kramers-Wannier duality is the prototypical example of a non-invertible symmetry, yet little is known about its fate away from criticality and out of equilibrium. We introduce…

Universality of Measurement-Induced Criticality under Symmetry-Breaking Measurements

Angelo Russotto, Filiberto Ares, Pasquale Calabrese

We study the critical properties of random quantum circuits with a symmetry subject to local projective measurements that explicitly break this symmetry. We find that, at th…

Symmetry Resolved Entanglement Entropy: Equipartition under Driven and Non-unitary Evolution in a Compact Boson CFT

Filiberto Ares, Jayashish Das, Arnab Kundu

We study the evolution of symmetry-resolved entanglement entropy in bulk-driven Floquet conformal field theories (CFTs). Focusing on the two-dimensional free compact boson CFT, we…

An asymmetry lower bound on fermionic non-Gaussianity

Filiberto Ares, Michele Mazzoni, Sara Murciano +3

Fermionic Gaussian states are a fundamental tool in many-body physics, faithfully representing non-interacting quantum systems and allowing for efficient numerical simulations. Giv…

Probing Entanglement and Symmetries in Random States Using a Superconducting Quantum Processor

Jia-Nan Yang, Lata Kh Joshi, Filiberto Ares +3

Quantum many-body systems display an extraordinary degree of complexity, yet many of their features are universal: they depend not on microscopic details, but on a few fundamental…

Dynamics of entanglement fluctuations and quantum Mpemba effect in the QSSEP model

Angelo Russotto, Filiberto Ares, Pasquale Calabrese +1

We study the out-of-equilibrium dynamics of entanglement fluctuations in the Quantum Symmetric Simple Exclusion Process, a free-fermion chain with hopping amplitudes that are…

Quantum Mpemba effect in long-range spin systems

Shion Yamashika, Filiberto Ares

One of the manifestations of the quantum Mpemba effect (QME) is that a tilted ferromagnet exhibits faster restoration of the spin-rotational symmetry after a quantum quench when st…
