Thermodynamic signatures of non-Hermiticity in Dirac materials via quantum capacitance
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 tests rely on wave-based or dynamical probes. Here…

Exceptional flat bands in bipartite non-Hermitian lattices
Juan Pablo Esparza, Vladimir Juričić
Flat bands, in which kinetic energy is quenched and quantum states become macroscopically degenerate, host a rich variety of correlated and topological phases, from unconventional…

Topological versus conventional superconductivity in a Weyl semimetal: A microscopic approach
Enrique Muñoz, Juan Pablo Esparza, José Braun +1
Starting from a microscopic model for the particle-particle interactions in a Weyl semimetal, we analyzed the possibility for conventional as well as monopole Cooper pairing betwee…
