Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Cold-atom-based inertial sensors employ ultra-cold neutral atoms to improve sensitivity and accuracy. Evaporative cooling is a widely used process to reach ultra-cold temperatures, and dynamic optical dipole traps (ODTs) have demonstrated <100 nano-Kelvin in evaporation timescales of 1 s. We previously developed a numerical model that predicted the evolution of temperature and atom number...

850. Temperature-Dependent Absorption Spectroscopy of a 87 87 Rb Vapor Cell for EIT-Based Quantum Memory

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Electromagnetically induced transparency (EIT)–based quantum memories require an atomic ensemble with sufficient optical depth and stable frequency detuning conditions. In this work, we characterize a Rb-87 atomic vapor cell by measuring near-resonant absorption (transmission) spectra under controlled temperature settings, aiming to identify suitable operating conditions for subsequent EIT...

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Magneto-optical traps (MOTs) are a central tool for producing and confining ultracold atomic gases. Most experiments rely on type-I MOTs, which exploit closed cycling transitions to provide strong radiation-pressure forces and efficient cooling. More recently, however, type-II MOTs, in which closed cycling transitions are absent, have been used in several laser cooling...

961. Ultracold radioactive atoms in an optical lattice

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Radioactive atoms and molecules are a new frontier in atomic physics currently being explored in cutting edge precision measurements. $^{221}$Fr’s nuclear octupole deformation gives ultracold FrAg molecules enhanced ability to detect hadronic CP violation. We are currently working towards studying atomic francium’s scattering properties through photoassociation spectroscopy. Toward this end,...

864. Design of an Untrapped Three-Photon Optical Clock with Bosonic Yb

Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Atomic clocks provide the most precise time and frequency standards, with applications in navigation, telecommunications, and precision tests of fundamental physics. We present the design and ongoing implementation of an optical clock architecture based on a three-photon transition in untrapped bosonic ytterbium. By interrogating ballistic Yb atoms using a coherent three-photon transition and...
