Collective thermalization, work reliability, and resource bounds in a population-inverted Dicke Otto engine
Cler T. Garcez, Gabriella G. Damas, Norton G. de Almeida +1
Population inversion and collective relaxation can both enhance the performance of a quantum heat engine, but through distinct mechanisms. We study a quantum Otto engine whose work…
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…
Shortcut-error signatures in coherence-retaining endpoint work quasistatistics
Gabriella G. Damas, G. D. de Moraes Neto
Quantum work statistics differ from classical ones because initial energy coherence matters. The standard two-point measurement (TPM) gives a positive distribution but erases phase…
Coherence-Preserving Fluctuation Diagnostics for an Engineered Population-Inverted Qubit Otto Engine
Gabriella G. Damas, Norton G. de Almeida, Gao Xianlong +1
Finite-time quantum thermal machines require diagnostics beyond average work and efficiency, because microscopic engines operate in regimes where fluctuations, incomplete thermaliz…
Engineered Kerr Nonlinearities for Precise Quantum Control of Fock States
Gabriella G. Damas, Ciro Micheletti Diniz, Norton G. de Almeida +2
We present a practical design framework for high-fidelity quantum control in coupled Kerr-nonlinear oscillators, directly addressing the challenge of spectral crowding. We show tha…
Probing the Limits of Dispersive Quantum Thermometry with a Nonlinear Mach-Zehnder-Based Quantum Simulator
Daniel Y. Akamatsu, Lucas Ferreira R. de Moura, Gabriella G. Damas +3
Temperature estimation, known as thermometry, is a critical sensing task for physical systems operating in the quantum regime. Indeed, thermal fluctuations can significantly degrad…
Quantum Features of the Thermal Two-Qubit Quantum Rabi Model in Ultra- and Deep-Strong Regimes
Ciro Micheletti Diniz, Gabriella G. Damas, Norton G. de Almeida +2
Quantum correlations and non-classical states are indispensable resources for advancing quantum technologies, and their resilience at finite temperatures is crucial for practical e…
Entropy production and efficiency enhancement in quantum Otto engines operating at negative temperatures
Aryadine F. de Sousa, Gabriella G. Damas, Norton G. de Almeida
Cyclic classical and quantum thermal machines show higher efficiency when the strokes are carried out quasi-statically. Recent theoretical and experimental work on figures of merit…
Cooling with fermionic reservoir
Gabriella G. Damas, Rogério J. de Assis, Norton G. de Almeida
Recently, much emphasis has been given to genuinely quantum reservoirs generically called fermionic reservoirs. These reservoirs are characterized by having finite levels, as oppos…
Negative temperature is cool for cooling
Gabriella G. Damas, Rogério J. de Assis, Norton G. de Almeida
In this work, we study an autonomous refrigerator composed of three qubits [Phys. Rev. Lett. 105, 130401 (2010)] operating with one of the reservoirs at negative temperatures, whic…
