Electromagnetic induced transparency and slow light in interacting quantum degenerate atomic gases

, 2012
We systematically develop the full quantum theory for the electromagnetic induced transparency (EIT) and slow light properties in ultracold Bose and Fermi gases.

Coupled cavities for enhancing the cross-phase modulation in electromagnetically induced transparency [PDF]

, 2000
We propose an optical double-cavity resonator whose response to a signal is similar to that of an Electromagnetically Induced Transparency (EIT) medium. A combination of such a device with a four-level EIT medium can serve for achieving large cross-Kerr ...

Double-EIT ground-state laser cooling without blue-sideband heating

, 2004
We discuss a laser cooling scheme for trapped atoms or ions which is based on double electromagnetically induced transparency (EIT) and makes use of a four-level atom in tripod configuration.

Mixing and Interpenetration in a Three-Dimensional Buoyancy-Driven Flow of Two Immiscible Liquids: A GPU Based LBM Approach

Journal of Applied Fluid Mechanics, 2021
The Buoyancy-driven flow of two immiscible liquids having varying density and viscosity is studied in a three-dimensional inclined confined channel. Initially, the heavier/lighter liquids occupy the upper/lower parts of the channel, respectively, which ...

High contrast D$_{1}$ line electromagnetically induced transparency in nanometric-thin rubidium vapor cell

, 2011
Electromagnetically induced transparency (EIT) on atomic D$_{1}$ line of rubidium is studied using a nanometric-thin cell with atomic vapor column length in the range of L= 400 - 800 nm. It is shown that the reduction of the cell thickness by 4 orders as
