Evaporative cooling by pulse width modulation (PWM) of optical dipole traps
S. Sagar Maurya, Joel M. Sunil, Monu Bhartiya +4
We introduce a method for cooling atoms in an optical dipole trap using pulse-width modulation (PWM) technique, without reducing the laser power of the dipole trap. The PWM techniq…
Detection of radiatively open systems using an optical cavity
V. I. Gokul, Arun Bahuleyan, Raghuveer Singh Yadav +4
We experimentally demonstrate a cavity-based detection scheme for a cold atomic ensemble with a radiatively open transition. Our method exploits the collective strong coupling of a…
Thermalization of a Trapped Single Atom with an Atomic Thermal Bath
Rahul Sawant, Anna Maffei, Giovanni Barontini
We studied a single atom trapped in an optical tweezer interacting with a thermal bath of ultracold atoms of a different species. Because of the collisions between the trapped atom…
Controlling the ac Stark effect of RbCs with dc electric and magnetic fields
Jacob A. Blackmore, Rahul Sawant, Philip D. Gregory +4
We investigate the effects of static electric and magnetic fields on the differential ac Stark shifts for microwave transitions in ultracold bosonic RbCs molecules,…
Collisional cooling of light ions by co-trapped heavy atoms
Sourav Dutta, Rahul Sawant, S. A. Rangwala
We experimentally demonstrate cooling of trapped ions by collisions with co-trapped, higher mass neutral atoms. It is shown that the lighter K ions, created by ionizin…
Optical control of resonant light transmission for an atom-cavity system
Arijit Sharma, Tridib Ray, Rahul V. Sawant +3
We demonstrate the manipulation of transmitted light through an optical Fabry-Perot cavity, built around a spectroscopy cell containing enriched rubidium vapor. Light resonant with…
