Probing cosmic expansion through small anisotropies in a Bose-Einstein condensate analogue
Miguel Citeli de Freitas, Thaïs Nivaille, Caio C. Holanda Ribeiro
In this letter, it is shown that by measuring quantities like density variance in the present state of an analogue universe one can assess information about its history due to the…

Analytical solutions for the quantum Brownian motion of a particle during a quantum quench
Ygor de Oliveira Souza, Caio C. Holanda Ribeiro, Vitorio A. De Lorenci
A particle subjected to a fluctuating force originated from its interaction with an external quantum system undergoes quantum Brownian motion. This phenomenon is investigated in de…
