Perturbative approach to the first law of quantum thermodynamics
Mario Reis, Maron F. Anka, Vinicius Gomes de Paula +1
In quantum thermodynamics, the decomposition of energy exchanges into heat and work remains an open problem beyond weak-coupling and slow-driving regimes. Recent formulations have…
Quantum Level-Crossing Induced by Anisotropy in Spin-1 Heisenberg Dimers: Applications to Quantum Stirling Engines
Bastian Castorene, Vinicius Gomez de Paula, Francisco J. Peña +3
This work explores the thermodynamic performance of a quantum Stirling heat engine implemented with an anisotropic spin-1 Heisenberg dimer as the working medium. Using the Hamilton…
Quantum caloric effects
Clebson Cruz, J. S. Amaral, Mario Reis
Quantum thermodynamics aims to explore quantum features to enhance energy conversion beyond classical limits. While significant progress has been made, the understanding of caloric…
Quantum Thermodynamics of a Power-Law Potential
Vinicius Gomes de Paula, Wanisson S. Santana, Clebson Cruz +1
Modeling quantum thermal machines provides a practical approach to describing the thermodynamic properties of quantum technologies and devices. For this purpose, power-law potentia…
Quantum Thermodynamics in Spin Systems: A Review of Cycles and Applications
Vinicius Gomes de Paula, Wanisson S. Santana, Clebson Cruz +1
Quantum thermodynamics is a powerful theoretical tool for assessing the suitability of quantum materials as platforms for novel technologies. In particular, the modeling of quantum…
