Quantum Flux from a Moving Spherical Mirror
نویسنده
چکیده
We calculate the flux from a spherical mirror which is expanding or contracting with nearly uniform acceleration. The flux at an exterior point (which could in principle be a functional of the mirror’s past history) is actually found to be a local function, depending on the first and second time derivatives of acceleration at the retarded time. 03.65.Pm,03.70.+k,11.15.Bt Typeset using REVTEX

Quantum radiation from a partially reflecting moving mirror
We consider the quantum radiation from a partially reflecting moving mirror for the massless scalar field in 1+1 Minkowski space. Partial reflectivity is achieved by localizing a δ-type potential at the mirror’s position. The radiated flux is exactly obtained for arbitrary motions as an integral functional of the mirror’s past trajectory. Partial reflectivity corrections to the perfect mirror r...
متن کاملQuantum Purity at a Small Price: Easing a Black Hole Paradox
Following Hawking, it is usual to mimic the effect of collapse space-time geometry on quantum fields in a semi-classical approximation by imposing suitable boundary conditions at the origin of coordinates, which effectively becomes a moving mirror. Suitable mirror trajectories induces a close analogue to the radiance of black holes, including a flux of outgoing radiation that appears accurately...
متن کاملBerry phase for a particle in an infinite spherical potential well with moving wall
In this paper we calculate the Berry phase for a wave function of a particle in an infinite spherical potential well with adiabatically varying. In order to do this, we need the solutions of the corresponding Schrödinger equation with a time dependent Hamiltonian. Here, we obtain these solutions for the first time. In addition, we calculate the Berry phase in one dimensional case for an infinit...
متن کاملDecaying D-branes and Moving Mirrors
We present an exact time-dependent solution to the effective D-brane worldvolume theory which describes an inhomogeneous decay of a brane-antibrane system. We compute the quantum energy flux induced by the particle creation in this inhomogeneous and time-dependent background. We find that this calculation is essentially equivalent to that of the moving mirror system. In the initial stage, the e...
متن کاملEfficient fluorescence collection from trapped ions with an integrated spherical mirror
Efficient collection of fluorescence from trapped ions is crucial for quantum optics and quantum computing applications, specifically for qubit state detection and in generating single photons for ion-photon and remote ion entanglement. In a typical setup, only a few percent of the ion fluorescence is intercepted by the aperture of the imaging optics. We employ a simple metallic spherical mirro...
