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…
Understanding two-photon double ionization of helium from the perspective of the characteristic time of dynamic transitions
Fei Li, Facheng Jin, Yujun Yang +4
By using the B-spline numerical method, we investigate a two-photon double-ionization (TPDI) process of helium in a high-frequency laser field with its frequency ranging from 1.6~a…
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…
Photoelectron angular distribution from the high-order above-threshold ionization process in IR+XUV two-color laser fields
Facheng Jin, Fei Li, Jing Chen +2
High-order above-threshold ionization (HATI) spectrum in IR+XUV two-color laser fields has been investigated. We found that the quantum features corresponding to the absorption of…
