Matter-Wave Squeezing from Gouy Phase: Toward a New Tool for Quantum Technology
Thiago M. S. Oliveira, Lucas S. Marinho, F. C. V. de Brito +2
We investigate the Gouy phase emerging from the time evolution of confined matter waves in a harmonic potential. Specifically, we analyze the quantum dynamics of a Gaussian wavepac…

Temperature and non-Markovian parameter estimation in quantum Brownian motion
João C. P. Porto, Carlos H. S. Vieira, Irismar G. da Paz +2
We investigate a quantum metrological protocol operating in a non-Markovian environment by employing the quantum Brownian motion (QBM) model, in which the system is linearly couple…
