Abstract: We show that for optical cavities with any finite dissipation, the term "cavity mode" should be understood as a solution to the Helmholtz equation with outgoing wave boundary conditions. Thi...

Abstract: The concept of photon lifetime in a cavity is shown to be non-relevant in the case where the cavity round-trip group delay is negative due to the presence of a strong intracavity negative di...

We propose a novel scheme for the preparation of a maximally entangled state of two atoms in an optical cavity. Starting from an arbitrary initial state, a singlet state is prepared as the unique fixe...

We propose to turn two distant resonant cavities e ectively into one by coupling them via an
optical ber which is coated with two-level atoms [Franson et al., Phys. Rev. A 70, 062302 (2004)].The len...
