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…
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…
Entropy-Seebeck ratio as a tool for elementary charge determination
Francisco J. Peña, Cesar Nuñez, Bastian Castorene +3
In this work, we investigate the relationship between the Seebeck coefficient , and the differential entropy per particle (DEP, ), as a tool for characterizing charge carri…
Magnonic Thermal Machines
N. Vidal-Silva, Francisco J. Peña, Roberto E. Troncoso +1
We propose a magnon-based thermal machine in two-dimensional (2D) magnetic insulators. The thermodynamical cycles are engineered by exposing a magnon spin system to thermal baths a…
