Quantum noise and correlations in resonantly enhanced wave mixing based on atomic coherence

M. D. Lukin, A. B. Matsko, M. Fleischhauer +1

We investigate the quantum properties of fields generated by resonantly enhanced wave mixing based on atomic coherence in Raman systems. We show that such a process can be used for…

Optical pumping in dense atomic media: Limitations due to reabsorption of spontaneously emitted photons

Michael Fleischhauer

Resonant optical pumping in dense atomic media is discussed, where the absorption length is less than the smallest characteristic dimension of the sample. It is shown that reabsorp…

Coherent population transfer beyond the adiabatic limit: generalized matched pulses and higher-order trapping states

M. Fleischhauer, R. Unanyan, B. W. Shore +1

We show that the physical mechanism of population transfer in a 3-level system with a closed loop of coherent couplings (loop-STIRAP) is not equivalent to an adiabatic rotation of…

Long-time dynamics of spontaneous parametric down-conversion and quantum limitations of conversion efficiency

Michael Fleischhauer, Oliver Veits

We analyze the long-time quantum dynamics of degenerate parametric down-conversion from an initial sub-harmonic vacuum (spontaenous down-conversion). Standard linearization of the…

Radiative atom-atom interactions in optically dense media: Quantum corrections to the Lorentz-Lorenz formula

Michael Fleischhauer, Susanne F. Yelin

Generalized single-atom Maxwell-Bloch equations for optically dense media are derived taking into account non-cooperative radiative atom-atom interactions. Applying a Gaussian appr…

Interacting Dark Resonances: Interference Effects Induced by Coherently Altered Quantum Superpositions

M. D. Lukin, S. F. Yelin, M. Fleischhauer +1

We predict the possibility of sharp, high-contrast resonances in the optical response of a broad class of systems, wherein interference effects are generated by coherent perturbati…

Theory of atomic diffraction from evanescent waves

Carsten Henkel, Hartmut Wallis, Nathalie Westbrook +4

We review recent theoretical models and experiments dealing with the diffraction of neutral atoms from a reflection grating, formed by a standing evanescent wave. We analyze diffra…

Photon trains and lasing : The periodically pumped quantum dot

C. Wiele, F. Haake, C. Rocke +1

We propose to pump semiconductor quantum dots with surface acoustic waves which deliver an alternating periodic sequence of electrons and holes. In combination with a good optical…

The Casimir force for passive mirrors

A. Lambrecht, M. -T. Jaekel, S. Reynaud

We show that the Casimir force between mirrors with arbitrary frequency dependent reflectivities obeys bounds due to causality and passivity properties. The force is always smaller…

Hypersurface Bohm-Dirac models

D. Duerr, S. Goldstein, K. Muench-Berndl +1

We define a class of Lorentz invariant Bohmian quantum models for N entangled but noninteracting Dirac particles. Lorentz invariance is achieved for these models through the incorp…
