TLDR
It is experimentally and theoretically demonstrated that the atomic coherence can be completely transferred or arbitrarily contributed among the different levels in a four-level atomic (tripod) scheme by a group of coupled pulse sequences.Abstract:
We experimentally and theoretically demonstrate that the atomic coherence can be completely transferred or arbitrarily contributed among the different levels in a four-level atomic (tripod) scheme by a group of coupled pulse sequences. This technique can be applied to the information conversion in slow-light storage, quantum logical gates, and so on, which is based on the atomic coherence effect.read more

Tunneling control of cavity linewidth narrowing via quantum interference in triangular quantum dot molecules
TL;DR: In this paper, a scheme for tunneling control of cavity linewidth narrowing by quantum interference in triangular-type triple quantum dots (TQDs) is proposed, which can result in the appearance of two transparency windows and a steep dispersion.

Coherence generation and population transfer in a three-level ladder system
TL;DR: In this article, the effect of spontaneous emission on coherence generation and population transfer in a three-level ladder atomic system driven by two pulses in counterintuitive order was explored, and it was shown that a large number of coherence and population transfers can be achieved even with spontaneous decay rate.

Electromagnetically Induced Transparency
TL;DR: Electromagnetic induced transparency is a technique for eliminating the effect of a medium on a propagating beam of electromagnetic radiation EIT may also be used, but under more limited conditions, to eliminate optical self-focusing and defocusing and to improve the transmission of laser beams through inhomogeneous refracting gases and metal vapors, as figure 1 illustrates.

Coherent population transfer among quantum states of atoms and molecules
TL;DR: In this paper, the authors discuss the technique of stimulated Raman adiabatic passage (STIRAP), a method of using partially overlapping pulses (from pump and Stokes lasers) to produce complete population transfer between two quantum states of an atom or molecule.
