Velocity of a Quantum Particle in a Classically Forbidden Region
Christian Beck, Sheldon Goldstein, Dustin Lazarovici +2
Recently, Sharoglazova et al. [Nature 643, 67 (2025)] proposed a procedure for determining the speed of a quantum particle in the classically forbidden region of a potential step,…
On the foundations of statistical mechanics
Marco Baldovin, Giacomo Gradenigo, Angelo Vulpiani +1
Although not as wide, and popular, as that of quantum mechanics, the investigation of fundamental aspects of statistical mechanics constitutes an important research field in the bu…
Arrival Times Versus Detection Times
Sheldon Goldstein, Roderich Tumulka, Nino Zanghì
How to compute the probability distribution of a detection time, i.e., of the time which a detector registers as the arrival time of a quantum particle, is a long-debated problem.…
On the Measurement of the Unruh Effect Through Extended Quantum Thermometers
M. Cardi, P. Solinas, N. Zanghì
The Unruh effect, predicting a thermal reservoir for accelerating systems, calls for a more refined understanding of measurement processes involving quantum systems as thermometers…
