Collective Dynamics in Spin Chains with Constrained Dissipation: Classically Fragile but Quantum Robust
Pietro Brighi, Gianluca Frazzei, Igor Lesanovsky +2
Collective non-equilibrium phenomena in many-body systems are strongly influenced by fluctuations, particularly in the vicinity of phase transitions, where the interplay between cl…
Pairing-induced phase transition in the non-reciprocal Kitaev chain
Pietro Brighi, Andreas Nunnenkamp
Investigating the robustness of non-reciprocity in the presence of competing interactions is central to understanding non-reciprocal quantum matter. In this work, we use reservoir…
Dissipative quantum North-East-Center model: steady-state phase diagram, universality and nonergodic dynamics
Pietro Brighi, Alberto Biella
In this work we study the dissipative quantum North-East-Center (NEC) model: a two-dimensional spin-1/2 lattice subject to chiral, kinetically constrained dissipation and coherent…
Finite steady-state current defies non-Hermitian many-body localization
Pietro Brighi, Marko Ljubotina, Federico Roccati +1
Non-Hermitian many-body localization (NH MBL) has emerged as a possible scenario for stable localization in open systems, as suggested by spectral indicators identifying a putative…
Probing the many-body localized spin-glass phase through quench dynamics
Pietro Brighi, Marko Ljubotina, Maksym Serbyn
Eigenstates of quantum many-body systems are often used to define phases of matter in and out of equilibrium; however, experimentally accessing highly excited eigenstates is a chal…
Restoring thermalization in long-range quantum magnets with staggered magnetic fields
Lucas Winter, Pietro Brighi, Andreas Nunnenkamp
Quantum systems with strong long-range interactions are thought to resist thermalization because of their discrete energy spectra. We show that applying a staggered magnetic field…
Anomalous transport in the kinetically constrained quantum East-West model
Pietro Brighi, Marko Ljubotina
We study a chaotic particle-conserving kinetically constrained model, with a single parameter which allows us to break reflection symmetry. Through extensive numerical simulations…
Non-reciprocal dynamics and the non-Hermitian skin effect of repulsively bound pairs
Pietro Brighi, Andreas Nunnenkamp
We study the dynamics of a Bose-Hubbard model coupled to an engineered environment which in the non-interacting limit is described by the celebrated Hatano-Nelson model. At strong…
Many-body localization proximity effect in two-species bosonic Hubbard model
Pietro Brighi, Marko Ljubotina, Dmitry A. Abanin +1
The many-body localization (MBL) proximity effect is an intriguing phenomenon where a thermal bath localizes due to the interaction with a disordered system. The interplay of therm…
Hilbert space fragmentation and slow dynamics in particle-conserving quantum East models
Pietro Brighi, Marko Ljubotina, Maksym Serbyn
Quantum kinetically constrained models have recently attracted significant attention due to their anomalous dynamics and thermalization. In this work, we introduce a hitherto unexp…
Localization of a mobile impurity interacting with an Anderson insulator
Pietro Brighi, Alexios A. Michailidis, Kristina Kirova +2
Thermalizing and localized many-body quantum systems present two distinct dynamical phases of matter. Recently, the fate of a localized system coupled to a thermalizing system view…
Propagation of Many-body Localization in an Anderson Insulator
Pietro Brighi, Alexios A. Michailidis, Dmitry A. Abanin +1
Many-body localization (MBL) is an example of a dynamical phase of matter that avoids thermalization. While the MBL phase is robust to weak local perturbations, the fate of an MBL…
Stability of mobility edges in disordered interacting systems
Pietro Brighi, Dmitry Abanin, Maksym Serbyn
Many-body localization provides a mechanism to avoid thermalization in isolated interacting quantum systems. The breakdown of thermalization may be complete, when all eigenstates i…
Effect of the Anomalous Diffusion of Fluctuating Cooper Pairs in the Density of States of Superconducting NbN Thin Films
Pietro Brighi, Marco Grilli, Brigitte Leridon +1
Recent scanning tunnelling microscopy experiments in NbN thin disordered superconducting films found an emergent inhomogeneity at the scale of tens of nanometers. This inhomogeneit…
