Spatio-temporal Monte Carlo modeling of loading and decay dynamics in an optical dipole trap
Sankalp Shandilya, Gunjan Verma, Kavish Bhardwaj +3
Here, we present our studies on intra-trap dynamics of an optical dipole trap (ODT) loaded from a Magneto-optical trap (MOT) of Rb atoms. A spatio-temporal Monte Carlo (MC)…
On damping of Rabi oscillations in two-photon Raman excitation in cold Rb atoms
Vijay Kumar, S. P. Ram, S. Singh +3
Two-photon Raman excitation between the ground hyperfine states and of Rb atom has been experimentally studied.…
Measurement of gravitational acceleration in a single laser operated atomic fountain
Kavish Bhardwaj, S. Singh, S. P. Ram +6
We present measurements on Earth's gravitational acceleration (g) using an in-house developed cold atom gravimeter (CAG) in an atomic fountain geometry. In the setup, the laser coo…
On trapping geometry for cold atoms in a radio-frequency (rf) dressed potential
Sourabh Sarkar, S. P. Ram, Kavish Bhardwaj +3
We have investigated the atom trapping geometry for trapping of atoms in a radio-frequency (rf) dressed potential generated after superposing a strong linearly polarize…
Pulsed loading of a magneto-optical trap on atom chip for fast pressure recovery in ultrahigh vacuum environment
Vivek Singh, V. B. Tiwari, A. Chaudhary +2
This study presents investigations on pulsed loading of a magneto-optical trap (MOT) on an atom chip in an UHV environment. Using three parallel resistively heated Rb-metal dispens…
Ultra-high vacuum pressure measurement using cold atoms
S. Supakar, Vivek Singh, V. B. Tiwari +1
In this work, we have measured the background pressure in an ultra-high vacuum (UHV) chamber by measuring the collisional loss rates in a Rb atom magneto-optical trap (MOT) on an a…
