High-resolution spectroscopy of barium monofluoride: Odd isotopologues, hyperfine structure and isotope shifts
Felix Kogel, Yuly Chamorro, Mangesh Bhattarai +5
Barium monofluoride (BaF) is a promising molecular species for precision tests of fundamental symmetries and interactions. We present a combined theoretical and experimental study…
Magnetic hyperfine structure constants of BaF in the and excited states
Yuly Chamorro, Felix Kogel, Tim Langen +1
High-precision molecular experiments testing the Standard Model of particle physics require an accurate understanding of the molecular structure at the hyperfine level, both for th…
Observation of electromagnetically induced absorption in a vee + ladder system
Mangesh Bhattarai, Vineet Bharti, Sambit Banerjee +1
We experimentally demonstrate electromagnetically induced absorption (EIA) in a vee + ladder system. The experiment is done using the low-lying energy levels of Rb. A theore…
Study of EIT resonances in an anti-relaxation coated Rb vapor cell
Mangesh Bhattarai, Vineet Bharti, Vasant Natarajan +2
We demonstrate---experimentally and theoretically---that resonances obtained in electromagnetically induced transparency (EIT) can be both bright and dark. The experiments are done…
Finding the number density of atomic vapor by studying its absorption profile
Harish Ravi, Mangesh Bhattarai, Vasant Natarajan
We demonstrate a technique for obtaining the density of atomic vapor, by doing a fit of the resonant absorption spectrum to a density-matrix model. In order to demonstrate the usef…
