Phys. Rev. A 83, 013819 (2011) [7 pages]Photon creation in a resonant cavity with a nonstationary plasma mirror and its detection with Rydberg atomsReceived 9 November 2010; published 21 January 2011 We investigate the dynamical Casimir effect and its detection with Rydberg atoms. The photons are created in a resonant cavity with a plasma mirror of a semiconductor slab which is irradiated by periodic laser pulses. The canonical Hamiltonian is derived for the creation and annihilation operators, showing the explicit time variation in the couplings, which originates from the external configuration such as a nonstationary plasma mirror. The number of created photons is evaluated as squeezing from the Heisenberg equations with the Hamiltonian. Then the detection of the photons as the atomic excitations is examined through the atom-field interaction. Some consideration is made for a feasible experimental realization with a semiconductor plasma mirror. © 2011 American Physical Society URL:
