Fluctuation and dissipation within a deformed holographic model with backreaction
Nathan G. Caldeira, Eduardo Folco Capossoli, Carlos A. D. Zarro +1
In this work we study the fluctuation and dissipation of a string attached to a brane in a deformed and backreated AdS-Schwarzschild spacetime. This space is a solution of Einstein…
Uniformly accelerated quantum counting detector in Minkowski and Fulling vacuum states
M. S. Soares, N. F. Svaiter, C. A. D. Zarro +1
In this work we discuss the process of measurements by a detector in an uniformly accelerated rectilinear motion, interacting linearly with a massive scalar field. The detector mod…
Fluctuation and Dissipation from a Deformed String/Gauge Duality Model
Nathan G. Caldeira, Eduardo Folco Capossoli, Carlos A. D. Zarro +1
Using a Lorentz invariant deformed string/gauge duality model at finite temperature we calculate the thermal fluctuation and the corresponding linear response, verifying the fluctu…
Functional equations for regularized zeta-functions and diffusion processes
Alexis Saldivar, Nami F. Svaiter, Carlos A. D. Zarro
We discuss modifications in the integral representation of the Riemann zeta-function that lead to generalizations of the Riemann functional equation that preserves the symmetry $s\…
A time-dependent harmonic oscillator with two frequency jumps: an exact algebraic solution
D. M. Tibaduiza, L. Pires, A. L. C. Rego +3
We consider a harmonic oscillator (HO) with a time dependent frequency which undergoes two successive abrupt changes. By assumption, the HO starts in its fundamental state with fre…
Radiative Processes of Entangled Detectors in Rotating Frames
Gabriel Picanço Costa, Nami Fux Svaiter, Carlos Augusto Domingues Zarro
We investigate the radiative processes of accelerated entangled two-level systems. Using first-order perturbation theory, we evaluate transition rates of two entangled Unruh-DeWitt…
