Oral (Non-Student) / Orale (non-étudiant(e))

In superconductors with multiple pairing channels, collective excitations known as "clapping modes" can arise in channels whose angular momenta differ from that of the pair condensate. Crystal symmetries often impose selection rules which keep these modes optically dark. We show that if pairing occurs around a single Fermi surface, trigonal warping renders clapping modes visible in the...

Oral (Non-Student) / Orale (non-étudiant(e))

The isolation of graphene with its remarkable electronic, optical, mechanical and chemical properties has led to the emergence of a range of two-dimensional (2D) materials with unique properties. A variety of metallic, semiconducting and insulating 2D materials have been discovered and are being explored for a diverse range of applications. Many of these materials can be produced at high...

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

Graphite, a stable allotrope of carbon, boasts unique properties including high electrical conductivity, and excellent thermal and chemical stability. Currently, the demand for graphite in both research and development is rapidly increasing. Despite the abundance of high quality of natural graphite, synthetic graphite remains attractive due to scalable production, controlled property tuning,...

Oral (Non-Student) / Orale (non-étudiant(e))

In the search for exotic entangled states in quantum magnets, understanding how disorder affects the stability and properties of quantum ground states remains an open problem. Quantum dimer magnets, where neighboring spins form entangled singlet pairs, provide a particularly clean platform for addressing this question.
Our study centers on the rare-earth dimer magnet BiYbGeO₅, previously...

973. Resonant X-ray Reflectometry of a Mn3Ge-based Quantum Heterostructure

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

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

Topological materials offer many interesting quantum phenomena such as anomalous Hall effect(AHE), topological Hall effect (THE), quantum spin liquid state, and skyrmion lattice. Among thesematerials, Mn3+xGe is one of the interesting materials as it has a triangular spin-lattice in the kagomenetwork. Due to this arrangement, collinear antiferromagnetic (AFM) alignment is impossible...

788. Visualizing Moiré Patterns and Lattice Reconstruction in Twisted Multilayer Graphene with Scanning Tunnelling Microscopy

Advancing Quantum Simulation based on 2 Dimensional Materials Through Canadian Collaboration / Faire progresser la simulation quantique basée sur les matériaux bidimensionnels grâce à une collaboration canadienne

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

Recent studies have proposed devices consisting of multiple graphene layers with near magic-angle twists as a promising platform for experimentally realizing correlated topological states. In such systems, moiré superlattices originating from consecutive layers are expected to experience lattice relaxation that significantly modifies the electronic band structure of the device.
Here we...

1019. Investigation of the role of Microstructural Refinement on Hydrogen Storage behavior of the γ-Mg17Al12 Intermetallic

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

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

Large-scale use of hydrogen is limited by storage and transport constraints due to its very low volumetric density as a diatomic gas at ambient conditions. Compression and cryogenic liquefaction increase density, but liquefaction requires cooling to ~20 K, consumes a notable fraction of the energy content, and is prone to boil-off and leakage. Metal hydrides offer solid-state storage by...
