Signatures of associative memory behavior in a multi-mode spin-boson model
Eliana Fiorelli, Matteo Marcuzzi, Pietro Rotondo +2
Spin-boson models can describe a variety of physical systems, such as atoms in a cavity or vibrating ion chains. In equilibrium these systems often feature a radical change in thei…
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…
Critical slowing down and entanglement protection
Eliana Fiorelli, Alessandro Cuccoli, Paola Verrucchi
We consider a quantum device interacting with a quantum many-body environment which features a second-order phase transition at . Exploiting the description of the cri…
Two-qubits in a large-S environment
Eliana Fiorelli, Alessandro Cuccoli, Paola Verrucchi
We analytically express the loss of entanglement between the components of a quantum device due to the generation of quantum correlations with its environment, and show that such l…
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…
