Investigation of a quantum mechanical detector model for moving, spread-out particles

摘要: We investigate a fully quantum mechanical spin model for the detection of moving particle. This model, developed in earlier work, is based on collection spins at fixed locations and metastable state, with particle locally enhancing coupling to an environment bosons. The appearance bosons from particular signals presence location, first boson indicates its arrival. original used discrete modes. Here we treat continuum limit, under assumption Markov property, calculate arrival-time distribution reach specific region.
