Lorentz-Covariant Spectral Bounds from Thermal Quantum Field Theory
Alisher Sanetullaev, Sarbinaz Bazarbaeva, Marhabo Beymamatova +1
We derive rigorous Lorentz-covariant bounds on relaxation spectra directly from the analytic structure of retarded Green's functions in thermal quantum field theory, using only cau…

Lorentz-Covariant Spectral Bounds from Thermal Quantum Field Theory: Retarded Green's Functions, Kubo Relations, and Holographic Constraints
Alisher Sanetullaev, Sarbinaz Bazarbaeva, Marhabo Beymamatova +1
We extend the recently established framework of Lorentz-covariant relaxation bounds from linearized classical kinetic and rheological theories to the full quantum setting of therma…
