    "abstract": "We propose and investigate a procedure to measure, at least in principle, a\npositive quantum version of the local kinetic energy density. This procedure is\nbased, under certain idealized limits, on the detection rate of photons emitted\nby moving atoms which are excited by a localized laser beam. The same type of\nexperiment, but in different limits, can also provide other non\npositive-definite versions of the kinetic energy density. A connection with\nquantum arrival time distributions is discussed.",
