Lossy Micromaser Battery: Almost Pure States in the Jaynes-Cummings Regime
Vahid Shaghaghi, Varinder Singh, Matteo Carrega +2
We consider a micromaser model of a quantum battery, where the battery is a single mode of the electromagnetic field in a cavity, charged via repeated interactions with a stream of…
Thermodynamic uncertainty relation in nondegenerate and degenerate maser heat engines
Varinder Singh, Vahid Shaghaghi, Özgür E. Müstecaplıoğlu +1
We investigate the thermodynamic uncertainty relation (TUR), \textit{i.e.} a trade-off between entropy production rate and relative power fluctuations, for nondegenerate three-leve…
Entanglement dynamics and classical complexity
Jiaozi Wang, Barbara Dietz, Dario Rosa +1
We study the dynamical generation of entanglement for a two-body interacting system, starting from a separable coherent state. We show analytically that in the quasiclassical regim…
Delayed Thermalization in Mass-Deformed SYK
Dillip Kumar Nandy, Tilen Cadez, Barbara Dietz +2
We study the thermalizing properties of the mass-deformed SYK model, in a regime of parameters where the eigenstates are ergodically extended over just portions of the full Fock sp…
Micromasers as Quantum Batteries
Vahid Shaghaghi, Varinder Singh, Giuliano Benenti +1
We show that a micromaser is an excellent model of quantum battery. A highly excited, pure, and effectively steady state of the cavity mode, charged by coherent qubits, can be achi…
Replica Symmetry Breaking in Random Non-Hermitian Systems
Antonio M. García-García, Yiyang Jia, Dario Rosa +1
Recent studies have revealed intriguing similarities between the contribution of wormholes to the gravitational path integral and the phenomenon of replica symmetry breaking observ…
Replica Symmetry Breaking for the Integrable Two-Site Sachdev-Ye-Kitaev Model
Yiyang Jia, Dario Rosa, Jacobus J. M. Verbaarschot
We analyze a two-body nonhermitian two-site Sachdev-Ye-Kitaev model with the couplings of one site complex conjugated to the other site. This model, with no explicit coupling betwe…
Quantum Chaos and Circuit Parameter Optimization
Joonho Kim, Yaron Oz, Dario Rosa
We explore quantum chaos diagnostics of variational circuit states at random parameters and study their correlation with the circuit expressibility and the optimization of control…
