Approaching the Inverse Neutron Scattering Problem with Neural Networks
Jingyi Luo, Fletcher Williams, Ang-Kun Wu +3
Determining the microscopic Hamiltonian of a quantum magnet from inelastic neutron scattering measurements remains a central challenge in condensed matter physics. While the dynami…
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…
Electronic anisotropy and rotational symmetry breaking at a Weyl semimetal/spin ice interface
Tsung-Chi Wu, Yueqing Chang, Ang-Kun Wu +10
In magnetic pyrochlore materials, the interplay of spin-orbit coupling, electronic correlations, and geometrical frustration gives rise to exotic quantum phases, including topologi…
Vacancy-induced tunable Kondo effect in twisted bilayer graphene
Yueqing Chang, Jinjing Yi, Ang-Kun Wu +5
In single sheets of graphene, vacancy-induced states have been shown to host an effective spin-1/2 hole that can be Kondo-screened at low temperatures. Here, we show how these vaca…
Disentangling Interacting Systems with Fermionic Gaussian Circuits: Application to Quantum Impurity Models
Ang-Kun Wu, Benedikt Kloss, Wladislaw Krinitsin +3
Tensor network quantum states are powerful tools for strongly correlated systems, tailored to capture local correlations such as in ground states with entanglement area laws. When…
The Aubry-Andre Anderson model: Magnetic impurities coupled to a fractal spectrum
Ang-Kun Wu, Daniel Bauernfeind, Xiaodong Cao +3
The Anderson model for a magnetic impurity in a one-dimensional quasicrystal is studied using the numerical renormalization group (NRG). The main focus is elucidating the physics a…
Fractal x-ray edge problem at the critical point of the Aubry-André model
Angkun Wu, Sarang Gopalakrishnan, J. H. Pixley
We study the Anderson orthogonality catastrophe, and the corresponding x-ray edge problem, in systems that are at a localization transition driven by a deterministic quasiperiodic…
