Radiatively Induced Lorentz and CPT Violation in QED at Finite Temperature
J. R. S. Nascimento, R. F. Ribeiro, N. F. Svaiter
In this paper we evaluate the induced Lorentz and CPT violating Chern-Simons term in the QED action at finite temperature. We do this using the method of derivative expansion of fe…

A Rotating Vacuum and the Quantum Mach's Principle
R. D. M. De Paola, N. F. Svaiter
In this work we consider a quantum analog of Newton's bucket experiment in a flat spacetime: we take an Unruh-DeWitt detector in interaction with a real massless scalar field. We c…
