Poster Competition (Graduate Student) / Compétition affiches (Étudiant(e) 2e ou 3e cycle)

We propose to investigate the breakdown of superfluidity in strongly correlated Li Fermi superfluids in a new trap geometry that allows for a long coherence time: a homogenous box with one periodic boundary condition. We will achieve this by trapping on the surface of a cylinder and introducing flexible barriers to superfluid flow. We report progress toward this new trap and prospects for...

Poster not-in-competition (Graduate Student) / Affiche non-compétitive (Étudiant(e) du 2e ou 3e cycle)

We revisit and expand upon previous results (1) related to He2+-Ne2 collisions to analyse electron-removal processes resulting in dimer fragmentation. The standard independent-electron multinomial analysis of single- and multi- electron transitions is compared to a Slater-determinant-based analysis that accounts for the Pauli principle. Given the orientation of a projectile travelling parallel...

The development of Photonic Crystal Fibers in the 1990s has led to considerable research on Supercontinuum generation, in which nonlinear effects play a big role. The majority of simulation work done to model the nonlinear Raman effect has been using the Generalized Nonlinear Schrödinger Equation (GNLSE) - which is computationally efficient but lacks accuracy in broadband modelling due to its...

4342. (G*) (POS-51) Deployable quantum memory systems in optical communications

Poster Competition (Graduate Student) / Compétition affiches (Étudiant(e) 2e ou 3e cycle)

A quantum internet of connected nodes requires the ability to send single photons across vast distances, something not possible with current fiber optic technology. A solution to this is the utilization of quantum repeater nodes which are reliant on a trustworthy quantum memory (QM) device. We will present a deployable quantum memory system that utilizes Electromagnetically Induced...

4328. (G) (POS-50) Nonrelativistic Eigenvalues and QED Effects for the High-$n$ Rydberg States of Helium

Poster not-in-competition (Graduate Student) / Affiche non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Variational calculations readily produce high precision energies and wave functions for the ground state, but typically the accuracy rapidly deteriorates with increasing principal quantum number n. The current limit is n = 10 [1,2]. We will report the results of new variational calculations based on the use of triple basis sets in Hylleraas coordinates. The basis sets are "tripled" in that...

Blood disorders, such as low iron anemia, affect almost one-third of Canadians. The symptoms range from extreme fatigue to shortness of breath. Considering these situations, early detection is paramount. A common diagnostic test for anemia is red blood cell count, but this process must be done at a lab and does not have an immediate turnaround time. High costs and less availably of equipment...

Canada plans to use a deep geological repository (DGR) system consisting of corrosion-resistant used fuel containers (UFCs) and other barriers to store spent nuclear fuel safely. Concerns arise regarding potential fuel exposure to groundwater, leading to fuel oxidation and dissolution due to water radiolysis by residual fuel radioactivity. Radionuclides within spent fuel, primarily located in...

Formation of microporous structures on a polymer surface leads to improved surface properties such as self-cleaning, anti-fogging, antibacterial characteristics, and strengthened adhesion with metals. Femtosecond laser-induced microporous structures (fs-LIMS) are microscale features created using laser technology for subsequent metal deposition. However, their quality is heavily influenced by...

The titanium oxide surface is responsible for many of the properties associated with the metal because it creates a hard, uniform, and thermodynamically stable protective coating over metallic titanium. Because of the characteristics of the oxide film, titanium has found uses in biomedical implants, aerospace engineering, industrial piping for corrosive environments, and other areas where high...

Many fundamental science processes and engineering designs are affected by the presence of hydrogen, e.g. hydrogen embrittlement. In order to understand fundamental issues in these materials and devices, quantifying the amount of hydrogen is needed. A method with high sensitivity is critical to improve current hydrogen analysis techniques to understand hydrogen related processes. To overcome...
