Spectrum and low-temperature bulk properties of triangular quantum spin liquid candidate NaYbSe
A. O. Scheie, Minseong Lee, Kevin Wang +18
We report neutron scattering, pressure-dependent AC calorimetry, and AC magnetic susceptibility measurements of triangular lattice NaYbSe. We observe a continuum of scattering,…
Simulating superconductivity in mixed-dimensional -- bilayers with neural quantum states
Hannah Lange, Ao Chen, Antoine Georges +3
Motivated by the recent discovery of superconductivity in the bilayer nickelate LaNiO (LNO) under pressure, we study a mixed-dimensional (mixD) bilayer -$J…
lrux: Fast low-rank updates of determinants and Pfaffians in JAX
Ao Chen, Christopher Roth
We present lrux, a JAX-based software package for fast low-rank updates of determinants and Pfaffians, targeting the dominant computational bottleneck in various quantum Monte Carl…
Superconductivity in the two-dimensional Hubbard model revealed by neural quantum states
Christopher Roth, Ao Chen, Anirvan Sengupta +1
Whether the ground state of the square lattice Hubbard model exhibits superconductivity remains a major open question, central to understanding high temperature cuprate superconduc…
Neural Network-Augmented Pfaffian Wave-functions for Scalable Simulations of Interacting Fermions
Ao Chen, Zhou-Quan Wan, Anirvan Sengupta +2
Developing accurate numerical methods for strongly interacting fermions is crucial for improving our understanding of various quantum many-body phenomena, especially unconventional…
