Two-point measurement energy statistics from particle scattering
arXiv:2302.06516 · doi:10.1103/PhysRevResearch.5.043160
Abstract
We show that the energy statistics resulting from a two-point measurement of an isolated quantum system subject to a time-dependent driving protocol can be probed by subjecting the same system to a collision with a suitably prepared incoming particle. This means that the particle acts both as an external drive and as an energy measurement device for the quantum system and that energy fluctuations can be defined within a fully autonomous setting.
