Abstract: Abstract We discuss the novel idea for direct terahertz pulse emission as a result of implementation of Purcell and Dicke effects simultaneously in the Nd 3+ heavily doped LaF 3 crystals after femtosecond near IR… read more here.

Abstract: Dicke superrandiance is a cooperative phenomenon which arises from the collective coupling of an ensemble of atoms to the electromagnetic radiation. Here we discuss the quantifying of quantum coherence for the Dicke model of superradiance… read more here.

DOI: 10.1364/oe.25.002790
Abstract: In 1954, Dicke predicted that a system of quantum emitters confined to a subwavelength volume would produce a superradiant burst. For such a burst to occur, the emitters must be in the special Dicke state… read more here.
