A Score-Based Model for Learning Neural Wavefunctions

no code implementations25 May 2023 Xuan Zhang, Shenglong Xu, Shuiwang Ji

Existing optimization approaches compute the energy by sampling local energy from an explicit probability distribution given by the wavefunction.

Lattice Convolutional Networks for Learning Ground States of Quantum Many-Body Systems

no code implementations15 Jun 2022 Cong Fu, Xuan Zhang, Huixin Zhang, Hongyi Ling, Shenglong Xu, Shuiwang Ji

Based on the proposed lattice convolutions, we design lattice convolutional networks (LCN) that use self-gating and attention mechanisms.

Hilbert Space Fragmentation and Exact Scars of Generalized Fredkin Spin Chains

no code implementations11 Feb 2021 Christopher M. Langlett, Shenglong Xu

In this work, based on the Fredkin spin chain, we introduce a family of spin-$1/2$ many-body Hamiltonians with a three-site interaction featuring a fragmented Hilbert space with coexisting quantum many-body scars.
