The formation of coherent macroscopic states and the manipulation of their entanglement
using external stimuli are essential for emerging quantum applications. However, the …

The research topic of air lasing is of fundamental and practical importance, which has grown
rapidly in the past decade. Air lasing, or a laser‐like emission from air species including …

Light–matter interactions can create and manipulate collective many-body phases in solids,–
, which are promising for the realization of emerging quantum applications. However, in …

Stand-off magnetometry allows measuring magnetic field at a distance, and can be
employed in geophysical research, hazardous environment monitoring, and security …

We investigated the superfluorescent decay process of dense rubidium atomic vapor in a
cell. Using a femtosecond laser pulse, the atoms were excited from the 5 S ground state to …

Temporal spiking of directional infrared and ultraviolet cooperative emission from sodium
vapors excited to the 4 D 5/2 level with a continuous-wave resonant laser pump is analyzed …

Picosecond and femtosecond superfluorescent beatings are observed from a dense atomic
vapor. Cesium atoms are excited by femtosecond laser pulses via two-photon processes …

In this paper, we study the propagation and time-evolution behavior of superfluorescence in
an overdamped semiconductor ring microcavity. By introducing a re-coupling mechanism …

Intriguing collective spontaneous cascade emissions have recently been realized. In despite
of much success, a depth understanding of the complexity is still lacking. With this …

We study backward cooperative emissions from a dense sodium atomic vapor. Ultrashort
pulses produced from a conventional amplified femtosecond laser system with an optical …
