Unitarity breaking in self-averaging spectral form factors
Apollonas S. Matsoukas-Roubeas, Mathieu Beau, Lea F. Santos +1
The complex Fourier transform of the two-point correlator of the energy spectrum of a quantum system is known as the spectral form factor (SFF). It constitutes an essential diagnos…
Large Deviations Beyond the Kibble-Zurek Mechanism
Federico Balducci, Mathieu Beau, Jing Yang +2
The Kibble-Zurek mechanism (KZM) predicts that the average number of topological defects generated upon crossing a continuous or quantum phase transition obeys a universal scaling…
Quantum delay in the time of arrival of free-falling atoms
Mathieu Beau, Lionel Martellini
Using standard results from statistics, we show that for Gaussian quantum systems the distribution of a time measurement at a fixed position can be directly inferred from the distr…
