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…
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…
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…
