Stable Recovery of Matrix Gauge Classes from Pointwise Invariants
Dexuan Zhou, Huajie Chen, Bernie Hsu +1
A parameterized matrix family on a configuration domain is determined by its physical content only up to a constant orthogonal change of basis. This gauge ambiguity…

Nearsightedness in Materials with Indirect Band Gaps
Huajie Chen, Juerong Feng, Christoph Ortner +1
We investigate the nearsightedness property in the linear tight binding model at zero Fermi-temperature. We focus on the decay property of the density matrix for materials with ind…

Stochastic Reconfiguration with Warm-Started SVD
Dexuan Zhou, Huajie Chen, Cheuk Hin Ho +2
The combination of the variational Monte Carlo (VMC) method with deep learning wave function architectures has led to several successes in ground-state calculations of quantum many…
