A comparison of Fraunhofer-type diffraction from an atomic single-slit and a molecular double-slit
Jibak Mukherjee, Kamal Kumar, Harpreet Singh +6
We measured the Q-value and the scattering angle distributions for non-dissociative state selective single electron capture in collisions of 7.5 keV H and 15 keV H with H…
Laser based optical interferometer manometer design for primary pressure standard in India
Manoj Das, Sandip Kumar Ghosh, Kuldeep Kumar +3
The SI unit of pressure, i.e. Pascal is realized with mechanical devices such as ultrasonic interferometer manometers and pressure balances for the pressure range 1 Pa to 100 kPa.…
Continuous two-photon source using a single quantum dot in a photonic crystal cavity
Harmanpreet Singh, Manoj Das, P. K. Pathak
We propose methods for realization of continuous two photon source using coherently pumped quantum dot embedded inside a photonic crystal cavity. We analyze steady state population…
Generation of the superposition of mesoscopic states of nano-mechanical resonator by a single two-level system
Manoj Das, J. K. Verma, P. K. Pathak
We propose measurement based conditional generation of superposition of motional states of nanomechanical resonator. We consider a two level quantum mechanical system coupled with…
Frequency ratio of Yb and Sr clocks with uncertainty at 150 s averaging time
Nils Nemitz, Takuya Ohkubo, Masao Takamoto +4
Transition frequencies of atoms and ions are among the most accurately accessible quantities in nature, playing important roles in pushing the frontiers of science by testing funda…
Frequency ratios of Sr, Yb and Hg based optical lattice clocks and their applications
Masao Takamoto, Ichiro Ushijima, Manoj Das +8
This article describes the recent progress of optical lattice clocks with neutral strontium (Sr), ytterbium (Yb) and mercury (Hg) atoms. In particular, we pr…
