Multiple pathway quantum beat spectroscopy
Frontiers in Physics, 2022 We investigate quantum beats by monitoring cooperative emission from rubidium vapor and demonstrate correlated beats via coupled emission channels. We develop a theoretical model, and our simulations are in good agreement with experimental results.

Emission of Nonclassical Radiation by Inelastic Cooper Pair Tunneling [PDF]
Physical Review Letters, 2017 We show that a properly dc-biased Josephson junction in series with two microwave resonators of different frequencies emits photon pairs in the resonators. By measuring auto- and inter-correlations of the power leaking out of the resonators, we demonstrate two-mode amplitude squeezing below the classical limit.

Inter-Organizational Control of Low-Carbon Production in a Supply Chain
IEEE Access, 2019 Increasing consumers' environmental awareness has drawn more firms' attention to low-carbon production. CO2 emission management control is a critical factor in the process of low-carbon production in a supply chain.

Enhanced robustness and dimensional crossover of superradiance in cuboidal nanocrystal superlattices
Physical Review Research, 2023 Cooperative emission of coherent radiation from multiple emitters (known as superradiance) has been predicted and observed in various physical systems, most recently in CsPbBr_{3} nanocrystal superlattices. Superradiant emission is coherent and occurs on

Cooperative torus mode emission of O-ring lasers
AIP Advances, 2020 Deformable ring lasers were fabricated by dispersing fluorescent dye (rhodamine 6G) in silicone rubber rings, i.e., the so-called O-rings. When excited with a pulsed green laser, an O-ring of 750 µm diameter exhibited a stimulated emission with a ...

Blue cooperative emission in Yb3+ - doped GeO2 - PbO glasses
Materials Research, 2006 Investigation of the blue cooperative luminescence in a binary composition of GeO2-PbO glasses with different Yb3+ concentrations is reported. High refractive index (1.96) and large transmission window (0.4 up to 5.0 µm) are characteristics of this ...
