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…
