Charge-dipole-dipole interactions in cold gases
Academia QuantumCharge-dipole interactions are very common interactions among atoms and molecules, especially materials that can emit light or contain free charges. The second-order charge-dipole interactions, proportional to

Dipolar Rydberg-atom gas prepared by adiabatic passage through an avoided crossing
New Journal of Physics, 2015 The passage of cold cesium 49S $_{1/2}$ Rydberg atoms through an electric-field-induced multi-level avoided crossing with nearby hydrogen-like Rydberg levels is employed to prepare a cold, dipolar Rydberg atom gas.

Experimental Study of Cs Isotropic and Anisotropic Polyatomic Rydberg Molecules [PDF]
, 2019 In this thesis, we investigate few-body physics and many-body physics of ultralong-range Rydberg molecules. Ultralong-range Rydberg molecules are formed through scattering processes between Rydberg electrons and ground state atoms.

Error-robust quantum signal processing using Rydberg atoms
Physical Review ResearchRydberg atom arrays have recently emerged as one of the most promising platforms for quantum simulation and quantum information processing. However, as is the case for other experimental platforms, the longer-term success of the Rydberg atom arrays in ...

Scanning electron microscopy of Rydberg-excited Bose–Einstein condensates
New Journal of Physics, 2014 We report on the realization of high resolution electron microscopy of Rydberg-excited ultracold atomic samples. The implementation of an ultraviolet laser system allows us to excite the atom, with a single-photon transition, to Rydberg states.

Collective Quantum Jumps of Rydberg Atoms
Physical Review Letters, 2012 We study an open quantum system of atoms with long-range Rydberg interaction, laser driving, and spontaneous emission. Over time, the system occasionally jumps between a state of low Rydberg population and a state of high Rydberg population. The jumps are inherently collective and in fact exist only for a large number of atoms.

Quadruple Bonding of Alkaline Earth Atoms in AeCLi4 (Ae = Be − Ba) Complexes
Journal of Computational Chemistry, Volume 47, Issue 18, July 5, 2026.Quantum chemical calculations of the complexes AeCLi4 (Ae = Be—Ba) show that the molecules have strong Ae‐Cli4 bonds, which consist of four dative bonds. The best signature of the chemical bonds is Ae CLi4. ABSTRACT The results of quantum chemical calculations of the complexes AeCLi4 (Ae = Be − Ba) are reported at the BP86‐D3(BJ)/def2‐QZVPP and CCSD(T)/

Tunable VUV photochemistry using Rydberg H-atom time-of-flight spectroscopy
, 2008 In this article, we report an experimental method for studying tunable vacuum ultraviolet (VUV) photochemistry using the H-atom Rydberg tagging technique. In this method, two VUV laser light beams were generated using nonlinear four-wave mixing scheme in
