Correspondence Principle for Many-Body Scars in Ultracold Rydberg Atoms
Physical Review X, 2021 The theory of quantum scarring—a remarkable violation of quantum unique ergodicity—rests on two complementary pillars: the existence of unstable classical periodic orbits and the so-called quasimodes, i.e., the nonergodic states that strongly overlap ...

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.Just as fingerprints reveal identity, spectroscopic fingerprints reveal molecular secrets. In this article, we show parts of the unique fingerprint of the sulfur–aromatic interaction. By measuring how this force alters the electronic structure of gas‐phase peptides, we provide a fundamental understanding of interactions that give insights into the ...

Stochastic switching in the Rydberg atomic ensemble
Optics Express, 2020 We demonstrated stochastic switching in a bistable system implemented with the Rydberg atomic ensemble, which is realized by cascaded Rydberg excitation in a cesium vapor cell. Measurement of Rydberg state’s population by means of the electromagnetically induced transparency allows us to investigate the nonlinear behavior in Rydberg atomic ensemble ...

Excited state spatial distributions in a cold strontium gas [PDF]
, 2012 This thesis describes the development of a new technique for measuring the spatial distribution of Rydberg atoms in a cold strontium gas. Strontium atoms are cooled and trapped in a magneto-optical trap and coherently excited to Rydberg states in a two ...

Probing state-to-state reaction dynamics using H-atom Rydberg tagging time-of-flight spectroscopy
, 2011 Probing state-to-state reaction dynamics using H-atom Rydberg tagging time-of-flight spectroscopyIn the last decade or so, the H-atom Rydberg tagging time-of-flight (HRTOF) technique has made a significant impact in the study of state-to-state reaction ...

Trapping potentials and quantum gates for microwave-dressed Rydberg atoms on an atom chip
Physical Review ResearchRydberg atoms in dc electric fields acquire static dipole moments. When the atoms are close to a surface producing an inhomogeneous electric field, such as by the adsorbates on an atom chip, depending on the sign of the dipole moment of the Rydberg-Stark

Exploring the vibrational series of pure trilobite Rydberg molecules
Nature Communications, 2023 In trilobite Rydberg molecules, an atom in the ground state is bound by electron-atom scattering to a Rydberg electron that is in a superposition of high angular momentum states.

Magnetic Polaronic Exciton in A‐Type 2D van der Waals Bulk Material CrSBr
Aggregate, Volume 7, Issue 6, June 2026.Schematic of the excitonic landscape in CrSBr. Multiple excitonic channels emerge below the charge‐transfer band edge (∼500 nm): isolated Cr3+ d–d excitons (PL1 ∼720 nm), magnetically activated dark excitons (PL1a ∼850 nm), ferromagnetically coupled excitons (PL2 ∼920 nm, maximum near 140 K), and interlayer excitons (PL3 ∼990 nm, vanishing above the ...

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media
Chemistry – A European Journal, Volume 32, Issue 21, 1 June 2026.This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...
