Coherent three-photon excitation of the strontium clock transition
Physical Review ResearchWe demonstrate coherent three-photon excitation of the strontium clock transition with a contrast of 51(12)% using a Bose-Einstein condensate. We follow it up with a demonstration of three-photon STIRAP-like transfer, overcoming the typical limitations ...

Quantum-Assisted Measurement of Atomic Diamagnetism
Physical Review X, 2020 We report the first measurement of ground-state diamagnetism of isolated neutral atoms in an atomic beam. We realize this measurement using magnetic deflection of fringes in a long-baseline matter-wave interferometer.

Laser cooling with adiabatic transfer on a Raman transition
New Journal of Physics, 2019 Sawtooth Wave Adiabatic Passage (SWAP) laser cooling was recently demonstrated using a narrow-linewidth single-photon optical transition in atomic strontium and may prove useful for cooling other atoms and molecules.

Ultracold atomic gases of strontium
, 2020 The thesis describes the design and construction of a new versatile strontium quantum gas machine with envisioned quantum gas microscope capability. The relevant theory for the operation of a quantum gas experiment in general is presented, as well as the peculiarities of working with strontium, and the calculation of a single-site single-atom detection

Single strontium atoms in optical tweezers
, 2023 This thesis shows our work towards trapping single strontium atoms inside tightly focused off-resonant laser beams, known as optical tweezers. More specifically, we demonstrate high-fidelity imaging of single strontium atoms using its narrow (7.4 kHz-wide) 1S0 - 3P1 transition. The atoms are trapped in non-magic-wavelength tweezers for this transition.
