Finite-size reliability of homothetic quantum Otto engines
Gabriella G. Damas, Clebson Cruz, Norton G. de Almeida +2
Homothetic quantum Otto engines---where all populated energy gaps are rescaled by a common factor---provide a reference model in which the quasistatic stochastic efficiency is traj…
Collective Mpemba-Type Relaxation in Degenerate Bosonic Modes Coupled to a Common Thermal Reservoir
I. M. de Araújo, H. Sanchez, L. F. Alves da Silva +2
We investigate collective Mpemba-type relaxation in a degenerate family of bosonic modes coupled to a common thermal reservoir. Starting from a fully symmetric M-mode description a…
Visibility-Engineered Multiparameter Sensing in Dispersive Quantum Interferometry: Identifiability, Noise Robustness, and Hardware Emulation
Lucas Ferreira R. de Moura, Daniel Y. Akamatsu, G. D. de Moraes Neto +1
We propose a dispersive interferometric protocol for simultaneously estimating the dimensionless inverse temperature of a thermal two-level ancilla and the dispersive…
Exploring the role of criticality in the quantum Otto cycle fueled by the anisotropic quantum Rabi-Stark model
He-Guang Xu, Jiasen Jin, Norton G. de Almeida +1
Quantum heat machines, encompassing heat engines, refrigerators, heaters, and accelerators, represent the forefront of quantum thermodynamics, offering a novel paradigm for convert…
