Manipulating the ground rotational state of a polar molecules still remains a challenge. The ground rotational state of a polar molecule is always a high field seeking state in DC fields and hence, challenging to be manipulated using DC Stark decelerator and static traps. Development of a microwave trap will enable us to trap the ground state of polar polyatomic molecules [1]. These ground state molecules are best suited for sympathetic cooling with ultra-cold atomic gases due to their low losses during the thermalization process.
In this work, we demonstrated that an unloaded quality factor of up to 1.1 × 106 at 24.087 GHz was achieved in a Fabry-Perot cavity coated with a superconducting material when cooled to 2.24 K [2]. With such strong microwave fields, we have detected the AC Stark shift of the |J, K >= |1, 1 > rotational levels of NH3. Experimental details and their results will be discussed.
