Measurement of the g factor of ground-state 87Sr at the parts-per-million level using co-trapped ultracold atoms
Premjith Thekkeppatt, Digvijay, Alexander Urech +2
We demonstrate nuclear magnetic resonance of optically trapped ground-state ultracold 87Sr atoms. Using a scheme in which a cloud of ultracold 87Rb is co-trapped nearby, we improve…

Confinement-induced resonances for the creation of quasi-one-dimensional ultra cold gases of alkali--alkaline-earth dimers
Lorenzo Oghittu, Premjith Thekkeppatt, Nirav P. Mehta +4
We theoretically investigate the role of confinement-induced resonances (CIRs) in low-dimensional ultracold atomic mixtures for the formation of weakly bound dimers. To this end, w…

High-power RF amplifier for ultracold atom experiments
Premjith Thekkeppatt, Edwin Baaij, Tijs van Roon +2
We report on the design and characterization of a high-power amplifier with an output power of 36.5 dBm for a frequency range of 50 MHz to 1000 MHz with a total gain of 40 dB. The…
