Quantum Properties of Solitons in and Models
Gabriel H. Flores, N. F. Svaiter
Recently we constructed two new -dimensional scalar field theory models that posses solitonic solutions. They are the and the mode…
Vacuum Polarization of a Scalar Field in a Rectangular Waveguide
R. B. Rodrigues, N. F. Svaiter
An analysis of the one-loop vacuum fluctuations associated with a scalar field confined in the interior of a infinite waveguide of rectangular cross section is presented. We first…
Vacuum Stress Tensor of a Scalar Field in a Rectangular Waveguide
R. B. Rodrigues, N. F. Svaiter, R. D. M. De Paola
Using the heat kernel method and the analytic continuation of the zeta function, we calculate the canonical and improved vacuum stress tensors, and ${Θ_{μν}(\ve…
Constructing Bidimensional Scalar Field Theory Models From Zero Mode Fluctuations
Gabriel H. Flores, N. F. Svaiter
In this paper we review how to reconstruct scalar field theories in two dimensional spacetime starting from solvable Schrodinger equations. Three different Schrodinger potentials a…
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…
