Disorder enhanced quantum many-body scars in Hilbert crystals
Bart van Voorden, Matteo Marcuzzi, Kareljan Schoutens +1
We consider a model arising in facilitated Rydberg chains with positional disorder which features a Hilbert space with the topology of a -dimensional hypercube. This allows for…
Dynamics of strongly coupled disordered dissipative spin-boson systems
Eliana Fiorelli, Pietro Rotondo, Federico Carollo +2
Spin-boson Hamiltonians are an effective description for numerous quantum many-body systems such as atoms coupled to cavity modes, quantum electrodynamics in circuits and trapped i…
Strong zero modes in a class of generalised Ising spin ladders with plaquette interactions
Loredana M. Vasiloiu, Federico Carollo, Matteo Marcuzzi +1
We study a class of spin- quantum ladder models with generalised plaquette interactions in the presence of a transverse field. We show that in certain parameter regimes these…
Discrete time crystals in the absence of manifest symmetries or disorder in open quantum systems
F. M. Gambetta, F. Carollo, M. Marcuzzi +2
We establish a link between metastability and a discrete time-crystalline phase in a periodically driven open quantum system. The mechanism we highlight requires neither the system…
Quantum accelerated approach to the thermal state of classical spin systems with applications to pattern-retrieval in the Hopfield neural network
Eliana Fiorelli, Pietro Rotondo, Matteo Marcuzzi +2
We explore the question as to whether quantum effects can yield a speedup of the non-equilibrium evolution of spin systems towards a classical thermal state. In our approach we exp…
Singularities in large deviations of work in quantum quenches
P. Rotondo, J. Minar, J. P. Garrahan +2
We investigate large deviations of the work performed in a quantum quench across two different phases separated by a quantum critical point, using as example the Dicke model quench…
