Enhanced Neural Quantum State via Annealed Gradient Descent
Shiwei Zhou, Yiming Huang, Xiao Yuan, Xiaoxia Cai
Neural quantum states offer expressive representations of quantum many-body wave functions, yet their practical accuracy can be limited by stochastic optimization rather than representational capacity. Here we identify a finite-sample instability, termed subspace trapping, in whi…
