This presentation introduces my recent work in the fields of quantum sensing and quantum optics. First, nitrogen-vacancy (NV) centers in diamond have attracted attention as magnetic field sensors with high spatial resolution. more

The combination of artificial magnetic fields with strong repulsive interactions is predicted to give rise to bosonic fractional-chern-insulator (FCI) ground states in the Hofstadter-Hubbard model, corresponding more

We find a fast non-adiabatic protocol for the creation of spin squeezed ground states in a spin-1 Bose condensate and experimentally generate those states near the quantum critical point more

With new methods for quantum devices comes the need for portability. A key component of atomic sensors is the vapor cell containing the atomic source. The first part of the talk is on the microfabrication of mm-sized rubidium vapor cells using silicon micromachining tools and techniques. more

Spin dynamics has, so far, mostly been studied in systems with isotropic spin–spin interactions. Here we use ultracold atoms to realize the anisotropic Heisenberg model, with fully adjustable anisotropy of the nearest-neighbor spin–spin couplings (the XXZ model). more

Atom interferometers are instruments that promise to offer devices greater sensitivity in measuring observables such as rotation, speed, acceleration, magnetic field, etc: As these interferometers make use of quantum effects however, they typically utilise several technologies including ultra-high vacuum chambers, RF electronic servos, laser systems and more making them rather complex. To advance the development of future commercial quantum devices more

The photoacoustic imaging (PAI) technique has been gaining a lot of attention in the past two decades due to its high contrast, scalable resolution, and relatively high imaging depth. PAI can be used for structural and functional imaging as well as for investigating tissue hemodynamics. There are multiple categories of PAI, one of which is acoustic resolution photoacoustic microscopy (AR-PAM). This type of imaging system uses focused transducers to capture generated photoacoustic signals in depth from a focused line. more
