The inverse Mpemba effect demonstrated on a single trapped ion qubit

Published in PRL, 2024

Here we propose a quantum analog of the Mpemba effect, on the simplest quantum system, a qubit. Specifically, we show it exhibits an inverse effect, in which a cold qubit reaches a hot temperature faster than a hot qubit. Furthermore, in our system a cold qubit can heat up exponentially faster, manifesting the strong version of the effect. This occurs only for sufficiently coherent systems, making this effect quantum mechanical, i.e. due to interference effects.

Calibration of the momentum scale of a particle physics detector using the Armenteros-Podolanski plot

Published in Journal of Instrumentation, 2021

A method for calibrating the momentum scale in a particle physics detector is described. The method relies on the determination of the masses of the final state particles in two-body decays of neutral particles, which can then be used to obtain corrections in the momentum scale. A modified version of the Armenteros-Podolanski plot and the KS0 → π+ π- decay is used as a proof of principle for this method. A precision at the 10-6–10-8 level is achieved in simplified simulations.
