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

Quantum sensors based on cold atoms have demonstrated unprecedented sensitivity, accuracy, and long-term stability that outcompetes “classical” sensors presently used for GPS-free positioning, navigation, and timing (PNT) systems. A crucial part of autonomous navigation is an accurate map of the local gravitational field. Portable absolute quantum gravimeters will enable higher-resolution...

45. Quantum quenches in the two-component Bose-Hubbard model

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

Cold atoms in optical lattices can be used as quantum simulators to study the temporal evolution of quantum systems, which has lead to increasing interest in the out-of-equilibrium dynamics of bosons in optical lattices. Adding a second species of bosons introduces a wide range of novel quantum phases and provides a platform to explore analogues of spin systems. We study the Bose-Hubbard model...

167. Tri-Modal Mosquito Bite Needle Endoscopy (MBNE) for Breast Cancer Diagnostics

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)

Purpose and Hypothesis: To lessen patient discomfort and improve breast cancer biopsy efficacy, a smaller, acupuncture sized needle should be used for core needle biopsies. Minimally invasive Mosquito Bite Needle Endoscopy (MBNE) using a 34-gauge acupuncture-sized needle with WAR tri-modal imaging could improve diagnostic accuracy and reduce unnecessary biopsies.

Methods: An 85-micron...

166. Confocal Microscopy and Tri-modal Optical Imaging for Breast and Thyroid Cancer Detection

Alex D'Ippolito (Toronto Metropolitan University)

09/06/2025, 15:00

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)

Purpose and Hypothesis:
A confocal microscope capable of accurate tissue pathology classification using a WAR tri-modal optical diagnosis system (White-light imaging, Autofluorescence imaging, and Raman spectroscopy) has the potential to improve the specificity and sensitivity to reliably diagnose breast cancer and thyroid cancer. The device will be used to build a database for Raman...

48. Painted optical potentials for rapid evaporative cooling of neutral atoms

Cristian Ramirez Rodriguez (University of New Brunswick)

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)

A coherent source of ultra-cold neutral atoms is a crucial prerequisite for state-of-the-art quantum sensors based on matter-wave interferometry, such as quantum gravimeters. Evaporative cooling is typically a slow process, often requiring tens of seconds, hence rapid cooling schemes are desirable to increase measurement rates. We present a numerical model for the evaporative cooling of...
