A universal time-of-arrival signature of Bose--Einstein condensation
Mathieu Beau, Timothey Szczepanski
We show that Bose--Einstein condensation produces a cusp in the time-of-arrival (TOA) statistics of a harmonically trapped gas released into free fall. In the semiclassical long ti…
Complementary Quantum Time Distributions from a Single Operational Protocol
Mathieu Beau
A single operational protocol based on free evolution and projective measurements yields inequivalent quantum time distributions through distinct post-processing procedures. We con…
Context-Dependent Time-Energy Uncertainty Relations from Projective Quantum Measurements
Mathieu Beau
We introduce a general framework for defining context-dependent time distributions in quantum systems using projective measurements. The time-of-flow (TF) distribution, derived fro…
Time-of-Flow Distributions in Discrete Quantum Systems: From Operational Protocols to Quantum Speed Limits
Mathieu Beau
We propose a general and experimentally accessible framework to quantify transition timing in discrete quantum systems via the time-of-flow (TF) distribution. Defined from the rate…
Quantum arrival times in free fall
Mathieu Beau, Timothey Szczepanski, Rafael Martellini +1
The probability distribution of a time measurement at position can be inferred from the probability distribution of a position measurement at time as given by t…
Time-of-arrival distributions for continuous quantum systems and application to quantum backflow
Mathieu Beau, Maximilien Barbier, Rafael Martellini +1
Using standard results from statistics, we show that for any continuous quantum system (Gaussian or otherwise) and any observable (position or otherwise), the distrib…
On the mutual exclusiveness of time and position in quantum physics and the corresponding uncertainty relation for free falling particles
Mathieu Beau, Lionel Martellini
The uncertainty principle is one of the characteristic properties of quantum theory, where it signals the incompatibility of two types of measurements. In this paper, we argue that…
Three-dimensional Quantum Slit Diffraction and Diffraction in Time
Mathieu Beau, T. C. Dorlas
We study the quantum slit diffraction problem in three dimensions. In the treatment of diffraction of particles by a slit, it is usually assumed that the motion perpendicular to th…
