Electromagnetically Induced transparency with Laguerre-Gaussian laser modes in ultracold rubidium
(2015-05)
We demonstrate electromagnetically induced transparency (EIT) using lasers in the Laguerre- Gaussian mode. The probe transmission is studied in an ultracold gas for the D2 line in both 85Rb and 87Rb. We consider the Lambda ...
Spectrum Formation at Late Times in Type Ia Supernovae
(2015-05-08)
I present a study of radiative transfer effects in type Ia supernovae ranging from 3-4 months to nearly 2 years post-maximum light. I explore several components of spectrum formation, beginning with a semi-analytic model ...
DETECTION OF "TRILOBITE" AND "BUTTERFLY" RYDBERG MOLECULES IN CESIUM WITH KILODEBYE DIPOLE MOMENTS
(2015-04-06)
The detection and characterization of two classes of ultralong-range Rydberg molecules known as "trilobite" and "butterfly" molecules is presented. These molecules are a subset of a class of Rydberg molecules which ...
Microwave Electrometry with Rydberg Eletromagnetically Induced Transparency in Vapor Cells
(2016-07-20)
An atom-based approach is presented to detect absolute microwave (MW) electric fields (E-fields). The approach uses Rydberg atoms in vapor cells at room temperature. The MW E-field measurements utilize a bright resonance ...
