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 ...

Coherent atom-light interactions in multi-level systems [PDF]
This thesis presents work on experiments performed using electromagnetically induced transparency (EIT) in Rubidium vapour cells. Starting with a simple three-level Λ-system, extra complexity is introduced by adding an additional control beam. This makes

Stochastic switching in the Rydberg atomic ensemble
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 ...

Energy Landscapes in Chemical Reactions and Transport
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

We experimentally investigate trap-loss spectra of the cesium 6S1/2(F = 4) → 71P3/2 Rydberg transition by combining the cesium atomic magneto-optical trap with the narrow-linewidth, continuously tunable 318.6 nm ultraviolet laser. Specifically, the atoms

High-order correction calculation for survival of Rydberg atoms in intense laser fields
Using a method based on the Magnus expansion, the survival of Rydberg atoms in intense laser fields is studied. Usually, for atoms in intense laser fields, effects beyond the electric dipole approximation need to be considered.

Rydberg dark states in external fields [PDF]
We initially discuss the theory of three-level systems using the dressed state formalism. One of the dressed states, containing a ground state and a Rydberg state, does not couple with the probe laser; thus, the medium becomes transparent to the latter ...

Correlations between interacting Rydberg atoms [PDF]
This paper is a short introduction to Rydberg physics and quantum nonlinear optics using Rydberg atoms. It has been prepared as a compliment to a series of lectures delivered during the Latin American School of Physics "Marcos Moshinsky" 2017. We provide

Magnetic Polaronic Exciton in A‐Type 2D van der Waals Bulk Material CrSBr
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 ...

Experimental Study of Cs Isotropic and Anisotropic Polyatomic Rydberg Molecules [PDF]
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.
