Observation of effects of inter-atomic interaction on Autler–Townes splitting in cold Rydberg atoms
New Journal of PhysicsWe demonstrate the effect of inter-atomic interaction in highly excited Rydberg atoms via Autler–Townes (AT) splitting in cold atoms. We measure the AT splitting of the $\{5S_{1/2}, F = 2\} \rightarrow \{5P_{3/2}, F^{^{\prime}} = 3\}$ transition of ^87 ...

Stability and Raman analysis of 1D carbon-boron nitride van der Waals heterostructure [PDF]
E3S Web of ConferencesIn this work, we investigate the one dimensional van der Waals heterostructures formed by single-walled carbon nanotubes (SWCNTs) trapped inside single-walled boron nitride nanotubes (SWBNNTs) by a combination of molecular dynamics, the bond ...

Magnetic field dependence of Raman coupling in Alkali atoms
, 2013 We calculate the magnetic field dependence of Rabi rates for two-photon optical Raman processes in alkali atoms. Due to a decoupling of the nuclear and electronic spins, these rates fall with increasing field.

From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage
Advanced Functional Materials, EarlyView.This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.

HESS J1809-193: Gamma-Ray Emission by Cosmic Rays from a Past Explosion
The Astrophysical JournalThe very-high-energy γ -ray source HESS J1809-193 has been detected by the LHAASO and HAWC observatory beyond 100 TeV energy. It is an interesting candidate for exploring the underlying mechanisms of γ -ray production due to the presence of supernova ...

State detection using coherent Raman repumping and two-color Raman transfers
, 2011 We demonstrate state detection based on coherent Raman repumping and a two-color Raman state transfer. The Raman coupling during detection selectively eliminates unwanted dark states in the fluorescence cycle without compromising the immunity of the ...
