Zero Point Density Fluctuations and Electron Brownian Motion
L. H. Ford, G. O. Heymans, N. F. Svaiter
The fluctuations in the phonon vacuum state can lead to zero point density fluctuations in a material, which in turn lead to local zero point fluctuations of the dielectric propert…
The weak and strong disorder regimes in the continuous random field Ising model
G. O. Heymans, N. F. Svaiter, B. F. Svaiter +1
We present a nonperturbative analysis of the weak- and strong-disorder regimes of the continuous random-field Ising model using the distributional zeta-function method. By performi…
Analog model for Euclidean wormholes: Bose-Einstein condensate with dirty surfaces
Isaque P. de Freitas, Nami F. Svaiter, Gustavo O. Heymans
We study a Bose-Einstein condensate under the effects of the non-condensate atomic cloud. We model the resulting linear interaction of the condensate with the atomic gas as a quenc…
The generalized second law in Euclidean Schwarzschild black hole
G. O. Heymans, G. Scorza, N. F. Svaiter +1
We discuss the Bekenstein generalized entropy of a Schwarzschild black hole, with the contribution of an external matter field affected by degrees of freedom near the event horizon…
The Casimir-Lifshitz formula for rectangular dielectric waveguide
E. Arias, G. O. Heymans, N. F. Svaiter
We analyze the Casimir-Lifshitz effect associated with the electromagnetic field in the presence of a rectangular waveguide consisting of two distinct dielectric materials in a $(3…
