The innuence of static disorder on the optical properties of microcavity-embedded quantum wells is studied by means of a microscopic model. Both the exciton-photon coupling and the exciton-disorder interaction are treated non-perturbatively. Despite the nonconservation of the in-plane momentum due to disorder, the Rabi splitting is still present. Moreover, the lower polari-ton is subject to mot...

For a transition Fe = 0 ↔ Fg = 1 driven by a linearly polarized light and probed by a circularly light, quantum coherence effects are investigated. Due to the coherence between the drive Rabi frequency and Zeeman splitting, electromagnetically induced transparency, electromagnetically induced absorption, and the transition from positive to negative dispersion are obtained, as well as the popula...

The ability to prepare, optically read out and coherently control single quantum states is a key requirement for quantum information processing. Optically active solid-state emitters have emerged as promising candidates with their prospects for on-chip integration as quantum nodes and sources of coherent photons connecting these nodes. Under a strongly driving resonant laser field, such quantum...

Although Josephson junction qubits show great promise for quantum computing, the origin of dominant decoherence mechanisms remains unknown. Improving the operation of a Josephson junction based phase qubit has revealed microscopic two-level systems or resonators within the tunnel barrier that cause decoherence. We report spectroscopic data that show a level splitting characteristic of coupling ...

The paper is a review of results on the asymptotic behavior of Markov processes generated by i.i.d. iterates of monotone maps. Of particular importance is the notion of splitting introduced by Dubins and Freedman (1966). Some extensions to more general frameworks are outlined, and, finally, a number of applications are indicated. *This paper is primarily based on my research with Professor Rabi...

A homogeneously broadened unidirectonal ring laser can emit in several longitudinal modes for large enough pump and cavity length because of Rabi splitting induced gain. This is the so called Risken-Nummedal–Graham-Haken (RNGH) instability. We investigate numerically the properties of the multi–mode solution. We show that this solution can coexist with the single–mode one, and its stability dom...

We discuss the quantum phase transition which separates a vacuum state with fully-gapped fermion spectrum from a vacuum state with topologically-protected Fermi points (gap nodes). In the context of condensed-matter physics, such a quantum phase transition with Fermi point splitting may occur for a system of ultra-cold fermionic atoms in the region of the BCS–BEC crossover, provided the Cooper ...

Here we demonstrate the optical features of fabricated inorganic-organic hybrid multiple quantum well (IO-MQW) structure, Cyclohexenyl ethyl ammonium lead iodide, (C6H9C2H4NH3)2PbI4 (CHPI). These hybrids possess strongly-resonant optical features, thermally stable and are compatible with hybrid photonics assembly. Room-temperature strong-coupling is observed when these hybrids are straightforwa...
