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…
Ultrafast creation of overlapping Rydberg electrons in an atomic BEC and Mott-insulator lattice
Michiteru Mizoguchi, Yichi Zhang, Masaya Kunimi +13
An array of ultracold atoms in an optical lattice (Mott insulator) excited to a state where single electron wave-functions spatially overlap would represent a new and ideal platfor…
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…
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…
Wavelength mismatch effect in electromagnetically induced absorption
Vineet Bharti, Ajay Wasan, Vasant Natarajan
We present a theoretical investigation of the phenomenon of electromagnetically induced absorption (EIA) in a 4-level system consisting of vee and ladder subsystems. The four level…
