Phase-Sensitive Heterodyne Detection of MW using EIT Harmonics in Rydberg Atoms
Mangesh Bhattarai, Rishav Hui, Sumanta Khan +3
We investigate the generation and characterization of higher-order harmonics in the probe-laser absorption arising from nonlinear interactions in an electromagnetically induced tra…
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…
Laser interferometry based on atomic coherence
Mangesh Bhattarai, Sumanta Khan, Vasant Natarajan +1
We demonstrate laser interferometry based on phase difference between the two arms of the interferometer. The experiments are done with a Cs atomic vapor cell at room temperature a…
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…
Tuning of the Hanle effect from EIT to EIA using spatially separated probe and control beams
Mangesh Bhattarai, Vineet Bharti, Vasant Natarajan
We demonstrate a technique for continuous tuning of the Hanle effect from electromagnetically induced transparency (EIT) to electromagnetically induced absorption (EIA) by changing…
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…
Polarization dependent tuning of the Hanle effect in the ground state of Cs
Harish Ravi, Mangesh Bhattarai, Vineet Bharti +1
We demonstrate that the Hanle effect can be tuned between magnetically induced absorption (MIA) and magnetically induced transmission (MIT) simply by changing the polarization of t…
Permanent EDM measurement in Cs using nonlinear magneto-optic rotation
Harish Ravi, Mangesh Bhattarai, Abhilash Y D +2
We use the technique of chopped nonlinear magneto-optic rotation (NMOR) in a room temperature Cs vapor cell to measure the permanent electric dipole moment (EDM) in the ato…
