Compact Spin-Charge Separated Neural Quantum States for Valence-Bond States
Ang-Kun Wu, Louis Primeau, Yixin Zhang +3
Neural-network quantum states (NQS) provide a flexible nonlinear representation of quantum many-body wavefunctions, but their efficiency depends sensitively on whether the architec…
Modeling Quantum Geometry for Fractional Chern Insulators with unsupervised learning
Ang-Kun Wu, Louis Primeau, Jingtao Zhang +3
Fractional Chern insulators (FCIs) in moire materials present a unique platform for exploring strongly correlated topological phases beyond the paradigm of ideal quantum geometry.…
Non-covalent Interactions at cm Accuracy: Data Efficient Physics-Informed Distillation for Machine Learning Interatomic Potentials
Yulin Shen, Shahzad Akram, Louis Primeau +4
Foundation models in atomistic machine learning encode interaction physics across diverse atomic environments, but whether that structure can be transferred when building specialis…
Angle-Resolved Berry Curvature via Nonlinear Hall Effect of Ballistic Electrons
Louis Primeau, Qiong Ma, Yang Zhang
Berry curvature fundamentally dictates the topological ground state, anomalous transport and optical properties of quantum materials. However, directly mapping its momentum-space d…
Interaction-Driven Topological Transitions in Monolayer TaIrTe
Jiangxu Li, Jian Tang, Louis Primeau +9
Discovering materials that combine topological phenomena with correlated electron behavior is a central pursuit in quantum materials research. Monolayer TaIrTe has recently eme…
Direct observation of a photoinduced topological phase transition in Bi-doped (Pb,Sn)Se
