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…
