Alok Kumar Singh

Research Fellow

Dr Alok Kumar Singh is an experimental Optical and Atomic Physicist and he works at precision hyperfine frequency measurements, coherent population trapping/oscillation, Bose-Fermi mixture, dipole-dipole/quadrupole Forster resonance transitions in Rydberg atoms and cold atoms for atomic clock. He has published on the impact of cold atoms, precision frequency measurements and coherent population trapping/oscillation. His recent research focuses on atomic optical lattice clock in cold Sr atoms. He works on atomics module of Miniature Optical Lattice Clock project and on iqClock- Integrated Quantum Clock project.
