Variational optimization of the amplitude of neural-network quantum many-body ground states

no code implementations18 Aug 2023 Jia-Qi Wang, Rong-Qiang He, Zhong-Yi Lu

Here, we split a quantum many-body variational wave function into a multiplication of a real-valued amplitude neural network and a sign structure, and focus on the optimization of the amplitude network while keeping the sign structure fixed.

A simple framework for contrastive learning phases of matter

no code implementations11 May 2022 Xiao-Qi Han, Sheng-Song Xu, Zhen Feng, Rong-Qiang He, Zhong-Yi Lu

A main task in condensed-matter physics is to recognize, classify, and characterize phases of matter and the corresponding phase transitions, for which machine learning provides a new class of research tools due to the remarkable development in computing power and algorithms.
