Narrow absorptive resonances in a four-level atomic system

M. G. Bason, A. K. Mohapatra, K. J. Weatherill +1

We study the effect of a control beam on a Lambda electromagnetically induced transparency (EIT) system in 87Rb. The control beam couples one ground state to another excited state…

Entanglement genesis under continuous parity measurement

Nathan S. Williams, Andrew N. Jordan

We examine the stochastic dynamics of entanglement for an uncoupled two-qubit system, undergoing continuous parity measurement. Starting with a fully mixed state, the entanglement…

Two-Pulse Propagation in a Partially Phase-Coherent Medium

B. D. Clader, J. H. Eberly

We analyze the effects of partial coherence of ground state preparation on two-pulse propagation in a three-level medium, in contrast to previous treastments that have consider…

Approximate quantum cloaking and almost trapped states

A. Greenleaf, Y. Kurylev, M. Lassas +1

We describe families of potentials which act as approximate cloaks for matter waves, i.e., for solutions of the time-independent Schrödinger equation at energy , with applicatio…

Electromagnetically induced transparency of an interacting cold Rydberg ensemble

K. J. Weatherill, J. D. Pritchard, R. P. Abel +3

We study electromagnetically induced transparency (EIT) of a weakly interacting cold Rydberg gas. We show that the onset of interactions is manifest as a depopulation of the Rydber…

Diagrammatic calculation of energy spectrum of quantum impurity in degenerate Bose-Einstein condensate

Alexey Novikov, Mikhail Ovchinnikov

In this paper we considered a quantum particle moving through delute Bose-Einstein condensate at zero temperature. In our formulation the impurity particle interacts with the gas o…

Giant electro-optic effect using polarizable dark states

A. K. Mohapatra, M. G. Bason, B. Butscher +2

The electro-optic effect, where the refractive index of a medium is modified by an electric field, is of central importance in non-linear optics, laser technology, quantum optics a…
