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…
Minimal Hamiltonian deformations as bulk probes of effective non-Hermiticity in Dirac materials
Sergio Pino-Alarcón, Juan Pablo Esparza, Vladimir Juričić
Non-Hermitian (NH) Dirac semimetals describe open gain--loss systems. Yet at charge neutrality, models featuring real spectrum often look Hermitian-like, with NH effects absorbed i…
