Sorted Mutability as an Entropic Functional: Theory and Two Applications
Michel Aguilera, Eugenio E. Vogel, Francisco J. Peña +2
We investigate sorted mutability, , as an information-based quantity with an explicit entropic character. We show that is directly proportional to the diversity of a dat…
Quantum Statistical Thermal Engine at the BCS-BEC crossover
Santiago Henríquez Lira, Felipe Isaule, Martín HvE Groves +3
We propose a quantum heat engine based on a two-component Fermi gas with s-wave contact interaction, operating across the BCS-BEC crossover. The work is extracted from the statisti…
Equilibrium Thermodynamics of Non-Hermitian Dirac Fermions: Caloric and Magnetic Responses
Francisco J. Peña, Bastian Castorene, Juan Pablo Esparza +2
We establish scaling relations governing the equilibrium thermodynamics of real-spectrum non-Hermitian Dirac fermions in a magnetic field. Assuming thermalization with respect to t…
Thermodynamic signatures of spectral compression in weakly non-Hermitian Dirac fermions
Juan Pablo Esparza, Francisco J. Peña, Patricio Vargas +1
Non-Hermitian band descriptions capture how loss, gain, and environmental coupling reshape quantum matter, yet most experimental probes remain wave based or dynamical. Here we deve…
Bosonic Working Media in a Frustrated Rhombi Chain: Otto and Stirling Cycles from Flat Bands, Caging, and Flux Control
Francisco J. Peña, Rafael García-Zamora, Gabriele De Chiara +5
We demonstrate that flat-band engineering provides a direct route to control and optimize the thermodynamic performance of quantum heat engines. We consider noninteracting bosons o…
Caloric Phenomena and Stirling-Cycle Performance in Heisenberg- Kitaev Magnon Systems
Bastian Castorene, Martin HvE Groves, Francisco J. Peña +5
We investigate the Stirling-cycle performance of a Heisenberg--Kitaev magnonic medium with Dzyaloshinskii--Moriya (DM) interactions. Using linear spin-wave theory, we show the DM i…
Thermal Hofstadter Butterflies
Natalia Cortés, Bastian Castorene, Francisco J. Peña +3
Fractal electronic spectra arising from the competition between lattice periodicity and magnetic flux are a fundamental hallmark of two-dimensional quantum systems. While the spect…
