Test of Causal Non-Linear Quantum Mechanics by Ramsey Interferometry on the Vibrational Mode of a Trapped Ion
Joseph Broz, Bingran You, Sumanta Khan +3
Kaplan and Rajendran have recently demonstrated that non-linear and state-dependent terms can be consistently added to quantum field theory to yield causal non-linear time evolutio…
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…
Observation of CPT for the ground hyperfine interval in Cs
Sumanta Khan, Vineet Bharti, Vasant Natarajan
We use the technique of coherent population trapping (CPT) to access the ground hyperfine interval (clock transition) in Cs. The probe and control beams required for CPT ar…
Coherent population pumping in a bright state
Sumanta Khan, Vineet Bharti, Vasant Natarajan
We demonstrate resonances due to coherent population pumping in a bright state (CBS), using magnetic sublevels of the closed transition in Rb…
Role of dressed-state interference in electromagnetically induced transparency
Sumanta Khan, Vineet Bharti, Vasant Natarajan
Electromagnetically induced transparency (EIT) in three-level systems uses a strong control laser on one transition to modify the absorption of a weak probe laser on a second trans…
Coherent population trapping (CPT) versus electromagnetically induced transparency (EIT)
Sumanta Khan, Molahalli Panidhara Kumar, Vineet Bharti +1
We discuss the differences between two well-studied and related phenomena---coherent population trapping (CPT) and electromagnetically induced transparency (EIT). Many differences…
