Dissipation, the irreversible loss of energy and coherence, from a microsystem is the result
of coupling to a much larger macrosystem (or reservoir) that is so large that one has no …

Publisher Summary This chapter describes the coherent population trap** in laser
spectroscopy. Coherent population trap** may be also described as the pum** of the …

In this paper, we propose a quantum interference mediated control of switching between
magnon-atom entanglement and magnon blockade. A three-level Λ configuration atomic …

We use the phase difference of two lasers with equal frequencies for the control of
spontaneous emission in a four-level system. Effects such as extreme spectral narrowing …

We study optical bistability (OB) behavior based on intersubband transitions in asymmetric
double quantum wells (QWs) where tunneling-induced quantum inference can be observed …

We analyze hybrid absorptive-dispersive optical bistability (OB) and multistability (OM)
behavior in a generic N-type atomic system driven by a degenerate probe field and a …

A theoretical investigation is carried out into the effect of spontaneously generated
coherence on the Kerr nonlinearity of general three-level systems of Λ, ladder, and V-shape …

We report on the coherent optical excitation of electron spin polarization in the ground state
of charged GaAs quantum dots via an intermediate charged exciton (trion) state. Coherent …

We demonstrate how the anisotropy of the vacuum of the electromagnetic field can lead to
quantum interferences among the decay channels of close lying states. Our key result is that …

Near-degenerate lower levels in a Λ system have an additional coherence term due to
interaction with the vacuum of the radiation field. We report the effects of this spontaneously …
