Quantum Ghost Spectroscopy Reveals Hidden Electronic Coherence in Molecular Aggregates
Mingran Zhang, Yihe Xu, Vladislav V. Yakovlev +1
Ultrafast spectroscopy of molecular systems is fundamentally constrained by the Fourier uncertainty principle: high temporal resolution smears out electronic state signatures, whil…
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-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…
Photon-resolved Floquet theory approach to spectroscopic quantum sensing
Georg Engelhardt, Konstantin Dorfman, Zhedong Zhang
Spectroscopic methods play a vital role in quantum sensing, which uses the quantized nature of atoms or molecules to reach astonishing precision for sensing of, e.g., electric or m…
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…
