Momentum-Resolved Electronic Structure for Quasicrystals: Full-Band Spectra and Chern Number
Donglin Yang, Huajie Chen, Dexuan Zhou +1
Quasicrystals lack the translational symmetry that underlies Bloch decomposition and Brillouin-zone integration, making full-band momentum-resolved electronic structure difficult t…
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…
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…
Mixed regularity and sparse grid approximations of -body Schrödinger evolution equation
Long Meng, Dexuan Zhou
In this paper, we present a mathematical analysis of time-dependent -body electronic systems and establish mixed regularity for the corresponding wavefunctions. Based on this, w…
