Collective resonance of states in rubidium atoms probed by optical two-dimensional coherent spectroscopy
Danfu Liang, Yifu Zhu, Hebin Li
Collective resonance of interacting particles has important implications in many-body quantum systems and their applications. Strong interactions can lead to a blockade that prohib…
Normal-mode splitting of four-level atom-cavity system under collective strong coupling
Zheng Tan, Liyong Wang, Min Liu +3
We investigate the transmission spectrum of an optical cavity coupled with four-level atoms. Multiple normal-mode splitting peaks of the strongly coupled atom-cavity system are obt…
Long range dipole-dipole interaction in atomic vapors probed by double-quantum two-dimensional coherent spectroscopy
Shaogang Yu, Michael Titze, Yifu Zhu +2
Optical double-quantum two-dimensional coherent spectroscopy (2DCS) was implemented to probe interatomic dipole-dipole interactions in both potassium and rubidium atomic vapors. Th…
Observation of scalable and deterministic multi-atom Dicke states in an atomic vapor
Shaogang Yu, Michael Titze, Yifu Zhu +2
Dicke state, a coherent state of multiple particles, is fundamentally responsible for various intriguing collective behaviors of many-body systems. Experimental access to Dicke sta…
Interference control of perfect photon absorption in cavity quantum electrodynamics
Liyong Wang, Ke Di, Yifu Zhu +1
We propose and analyze a scheme for controlling coherent photon transmission and reflection in a cavity-quantum-electrodynamics (CQED) system consisting of an optical resonator cou…
Perfect photon absorption in nonlinear regime of cavity quantum electrodynamics
G. S. Agarwal, Ke Di, Liyong Wang +1
It has been shown that perfect photon absorption can occur in the linear excitation regime of cavity quantum electrodynamics (CQED), in which photons from two identical light field…
