Controlling the ac Stark effect of RbCs with dc electric and magnetic fields (2020)
Journal Article
Blackmore, J. A., Sawant, R., Gregory, P. D., Bromley, S. L., Aldegunde, J., Hutson, J. M., & Cornish, S. L. (2020). Controlling the ac Stark effect of RbCs with dc electric and magnetic fields. Physical Review A, 102(5), Article 053316. https://doi.org/10.1103/physreva.102.053316

We investigate the effects of static electric and magnetic fields on the differential ac Stark shifts for microwave transitions in ultracold bosonic 87Rb133Cs molecules, for light of wavelength λ=1064nm. Near this wavelength we observe unexpected two... Read More about Controlling the ac Stark effect of RbCs with dc electric and magnetic fields.

Sticky collisions of ultracold RbCs molecules (2019)
Journal Article
Gregory, P. D., Frye, M. D., Blackmore, J. A., Bridge, E. M., Sawant, R., Hutson, J. M., & Cornish, S. L. (2019). Sticky collisions of ultracold RbCs molecules. Nature Communications, 10(1), Article 3104. https://doi.org/10.1038/s41467-019-11033-y

Understanding and controlling collisions is crucial to the burgeoning field of ultracold molecules. All experiments so far have observed fast loss of molecules from the trap. However, the dominant mechanism for collisional loss is not well understood... Read More about Sticky collisions of ultracold RbCs molecules.

Detection of ultracold molecules using an optical cavity (2018)
Journal Article
Sawant, R., Dulieu, O., & Rangwala, S. (2018). Detection of ultracold molecules using an optical cavity. Physical Review A, 97(6), Article 063405. https://doi.org/10.1103/physreva.97.063405

We theoretically study nondestructive detection of ultracold molecules, using a Fabry-Pérot cavity. Specifically, we consider vacuum Rabi splitting where we demonstrate the use of collective strong coupling for detection of molecules with many partic...

Lasing by driven atoms-cavity system in collective strong coupling regime (2017)
Journal Article
Sawant, R., & Rangwala, S. (2017). Lasing by driven atoms-cavity system in collective strong coupling regime. Scientific Reports, 7(1), Article 11432. https://doi.org/10.1038/s41598-017-11799-5

The interaction of laser cooled atoms with resonant light is determined by the natural linewidth of the excited state. An optical cavity is another optically resonant system where the loss from the cavity determines the resonant optical response of t...
