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…
Collective Quantum Entanglement in Molecular Cavity Optomechanics
Jian Huang, Dangyuan Lei, Girish S. Agarwal +1
We propose an optomechanical scheme for reaching quantum entanglement in vibration polaritons. The system involves molecules, whose vibrations can be fairly entangled with plas…
Multidimensional Coherent Spectroscopy of Molecular Polaritons: Langevin Approach
Zhedong Zhang, Xiaoyu Nie, Dangyuan Lei +1
We present a microscopic theory for nonlinear optical spectroscopy of N molecules in an optical cavity. A quantum Langevin analytical expression is derived for the time- and freque…
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…
Intrinsic Superflat Bands in General Twisted Bilayer Systems
Hongfei Wang, Shaojie Ma, Shuang Zhang +1
Twisted bilayer systems with discrete magic angles, such as twisted bilayer graphene featuring moiré superlattices, provide a versatile platform for exploring novel physical proper…
Phyllotaxis-inspired Nanosieves with Multiplexed Orbital Angular Momentum
Zhongwei Jin, David Janoschka, Junhong Deng +15
Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge as miniaturized, ultracompact and kaleidoscopic optical vortex ge…
