Quantum-Enhanced Sensing of Excited-State Dynamics with Correlated Photons

Jiahao Joel Fan, Feihong Liu, Dangyuan Lei +1

The squeezed photons, as a quantum-correlated light with reduced noise, have emerged as a great resource for sensing the structures of matter. Here we study the transient absorptio…

Fröhlich Condensation of Bosons: Graph texture of curl flux network for nonequilibrium properties

Feihong Liu, Chase Slowey, Xuanhua Wang +4

Nonequilibrium condensates of bosons subject to energy pump and dissipation are investigated, manifesting the Fröhlich coherence proposed in 1968. A quantum theory is developed to…

Quantum Fluctuations and Coherence of a Molecular Polariton Condensate

Zhedong Zhang, Shixuan Zhao, Dangyuan Lei

A full quantum theory beyond the mean-field regime is developed for an exciton polariton condensate, to gain a complete understanding of quantum fluctuations. We find analytical so…
