Structure of the Alkali-metal-atom-Strontium molecular ions: towards photoassociation and formation of cold molecular ions

, 2011
The potential energy curves, permanent and transition dipole moments, and the static dipolar polarizability, of molecular ions composed of one alkali-metal atom and a Strontium ion are determined with a quantum chemistry approach.

Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

Advanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

Narrow-line-mediated Sisyphus cooling in the ^{3}P_{2} metastable state of strontium

Physical Review Research
We demonstrate narrow-line-mediated Sisyphus cooling of magnetically trapped strontium (Sr) in the 5s5p^{3}P_{2} state. A 641nm standing-wave, blue detuned from the 5s4d^{3}D_{3}→ 5p4d^{3}F_{4} transition, creates a dissipative optical lattice in the ^{3}

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.

Phase-modulation detection of a strontium-atom-interferometer gyroscope

Physical Review Applied
We demonstrate a strontium thermal beam atom interferometer gyroscope (AIG) on a rotation table using the $^{1\!}S_0$-$ ^{3\!}P_1$ intercombination line, and measure large rotation rates exceeding 6 rad/s. Our demonstration relies upon a transit-time-resonant (TTR), phase modulation technique for detecting the AIG phase which rejects signal background ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
