A quantum model of lasing without inversion
New Journal of Physics, 2022 Starting from a quantum description of multiple Λ-type three-level atoms driven with a coherent microwave field and incoherent optical pumping, we derive a microscopic model of lasing from which we move towards a consistent macroscopic picture.

A Note on Cumulant Technique in Random Matrix Theory
Entropy, 2023 We discuss the cumulant approach to spectral properties of large random matrices. In particular, we study in detail the joint cumulants of high traces of large unitary random matrices and prove Gaussian fluctuation for pair-counting statistics with non ...

Mitigating Large Background in Jet Substructure Observables [PDF]
EPJ Web of Conferences, 2020 We discuss a new approach for jet physics analysis by using subtraction between cumulants of jet substructure observables. The subtracted cumulants are insensitive to soft-particle background uncorrelated with the hard process and allow comparisons ...

Underground signal recognition method based on higher-order cumulants and DNN model
Gong-kuang zidonghua, 2020 In view of complex and heterogeneous wireless environment of mine, an underground signal recognition method based on higher-order cumulants and DNN model was proposed to realize automatic modulation recognition of underground digital signals of BPSK ...

Photographing the wave function of the Universe [PDF]
, 1999 We show that density fluctuations in standard inflationary scenarios may take the most general non-Gaussian distribution if the wave function of the Universe is not in the ground state.

Multicyclic D‐Stereospecific Hydrolase Dimer With High Sustained Activity
Angewandte Chemie, EarlyView.Protein macrocyclization was applied to a thermally unstable D‐stereospecific hydrolase using in situ cyclization of proteins (INCYPRO). This site‐specific cross‐linking approach enhanced the resistance of the enzyme to heat and cosolvents.
