Prototype Superfluid Gravitational Wave Detector
V. Vadakkumbatt, M. Hirschel, J. Manley +3
We study a cross-shaped cavity filled with superfluid He as a prototype resonant-mass gravitational wave detector. Using a membrane and a re-entrant microwave cavity as a sensi…
Effect of AC-Stark shift in optical dipole trap on absorption imaging of trapped atoms
K Bhardwaj, S P Ram, S Singh +2
In the present work, the effect of AC-Stark shift (i.e. light-shift) in optical dipole trap on in-situ absorption probe imaging of the trapped atoms has been investigated. We have…
Observation of dual electromagnetically induced transparencies in cold atoms
Charu Mishra, A. Chakraborty, S. P. Ram +3
We have observed two dual electromagnetically induced transparency (EIT) spectra in probe transmission through cold atoms trapped in a magneto-optical trap (MOT). These d…
Distribution of current fluctuations in a bistable conductor
S. Singh, J. T. Peltonen, I. M. Khaymovich +3
We measure the full distribution of current fluctuations in a single-electron transistor with a controllable bistability. The conductance switches randomly between two levels due t…
Electromagnetically induced absorption in metastable 83Kr atoms
Y. B. Kale, V. B. Tiwari, S. R. Mishra +2
We report electromagnetically induced absorption (EIA) resonances of sub-natural linewidth (FWHM) in metastable noble gas 83Kr* atoms using degenerate two level schemes (DTLSs). Th…
Coupling nanomechanical cantilevers to dipolar molecules
S. Singh, M. Bhattacharya, O. Dutta +1
We investigate the coupling of a nanomechanical oscillator in the quantum regime with molecular (electric) dipoles. We find theoretically that the cantilever can produce single-mod…
