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

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

In recent years, Neural (network) Quantum States (NQS) emerged as powerful and reliable variational ansätze for studying strongly correlated quantum many-body systems. Since then, architectures such as restricted Boltzmann machines, recurrent neural networks, and convolutional neural networks, have been employed as wave function ansätze in variational Monte Carlo approaches to finding ground...

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)

Cross-linked polyethylene (PEX) pipes are being used increasingly for water transport and heating applications. The pipes are exceptionally reliable but sometimes unexpected failures occur. We are using infrared microscopy, accelerated aging and machine learning analysis techniques to understand the mechanisms of pipe aging, degradation and failure [1-3]. In previous studies, we implemented...

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

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

In chaotic dynamics, the eigenstate thermalization hypothesis (ETH) posits that quantum systems evolve toward an equilibrium state over time, regardless of their initial state. Equivalently, the expectation value of an observable with few degrees of freedom will relax towards a thermal value despite the wavefunction evolving through time [1]. However, there exist quantum mechanical phenomena...

616. Exploring Alternative Layered Materials as Gate Dielectrics for 2D Material Based Devices

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)

The performance and scalability of two-dimensional (2D) materials based quantum electronics devices critically depends on the choice of gate dielectric. In gate-defined quantum devices, high-κ dielectrics enhance electrostatic control and reduce gate leakage. Hexagonal boron nitride (hBN), a 2D layered material, has become a widely used dielectric due to the clean interface it forms with 2D...
