DOI: 10.1016/j.jlumin.2016.08.058

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.

DOI: 10.1088/1402-4896/ae01f8

Abstract: A theoretical scheme is proposed to simulate the quantum phase transitions (QPTs) of the three-level Dicke model. In this designed hybrid system, an ensemble of solid-state spins can simultaneously couple to a superconducting microwave (MW)… read more here.

DOI: 10.1103/physreva.102.053716

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: 10.1103/xcxr-sm9c

Abstract: We show that idealized Dicke superradiant decay from a fully inverted state can at all times be described by a positive statistical mixture of coherent spin states (CSS). Since CSS are separable, this implies that… 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.
