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…

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…
