Casimir Self-Entropy of an Electromagnetic Thin Sheet
Yang Li, K. A. Milton, Pushpa Kalauni +1
Casimir entropies due to quantum fluctuations in the interaction between electrical bodies can often be negative, either caused by dissipation or by geometry. Although generally su…
Operator description for thermal quantum field theories on an arbitrary path in the real time formalism
Ashok Das, Pushpa Kalauni
We develop an operator description, much like thermofield dynamics, for quantum field theories on a real time path with an arbitrary parameter . We point out new…
Negative Entropies in Casimir and Casimir-Polder Interactions
Kimball A. Milton, Li Yang, Pushpa Kalauni +5
It has been increasingly becoming clear that Casimir and Casimir-Polder entropies may be negative in certain regions of temperature and separation. In fact, the occurrence of negat…
Stress tensor for a scalar field in a spatially varying background potential: Divergences, "renormalization," anomalies, and Casimir forces
Kimball A. Milton, Stephen A. Fulling, Prachi Parashar +2
Motivated by a desire to understand quantum fluctuation energy densities and stress within a spatially varying dielectric medium, we examine the vacuum expectation value for the st…
