Spectroscopy and Conformer‐Selective Photoelectron Circular Dichroism of Chiral Molecules
Chemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.Photoelectron circular dichroism (PECD) is a forward–backward asymmetry in the angular distribution of the electrons emitted by a chiral molecule ionized by a circularly polarized light (CPL). Its sensitivity to conformation is studied by one‐photon or resonance‐enhanced two‐photon ionization, the latter being conformer‐selective.

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.

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems
Laser &Photonics Reviews, Volume 20, Issue 10, 22 May 2026.This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

Insights Into Bifenthrin Stereoisomers and Their Regulatory Implications
ChemistryOpen, Volume 15, Issue 5, May 2026.Bifenthrin is a pyrethroid insecticide with two stereogenic centers, generating four stereoisomers with distinct physicochemical and electronic properties. A combined crystallographic and density functional theory study, supported by Hirshfeld surface, quantum theory of atoms in molecules, natural bond orbital, and reactivity descriptor analyses ...

Journal of Physics: Conference Series, 2014 The local position invariance of a physical system is examined using a Rydberg atom and the universality of free fall is found to be invalid for a quantum system. A Rydberg atom is analysed in Newtonian gravity and curved space. The energy is found to vary as n2 for very large values of the principal quantum number n. The change in energy is calculated

Rydberg Molecules and Circular Rydberg states in Cold Atom Clouds. [PDF]
, 2015 In this dissertation I investigate cold Rydberg atoms and molecules in which the angular-momentum character of the quantum states involved strongly influences their properties and dynamics.

MICROWAVE AND SURFACE ELECTROMETRY WITH RYDBERG ATOMS [PDF]
, 2016 Measurements of microwave electric fields in rubidium vapor cells, and of static electric fields near quartz with cold rubidium are presented. The measurements are performed using electromagnetically induced transparency (EIT) with Rydberg atoms.

Study on the dissociative recombination of HeH+ by multi-channel quantum defect theory
EPJ Web of Conferences, 2015 The dissociative recombination of HeH+ is studied using multi-channel quantum defect theory. We investigated how the partial waves of incident electrons affect the DR cross section.
