A non-Hermitian Ground State Searching Algorithm Enhanced by Variational Toolbox
Yu-Qin Chen, Shi-Xin Zhang, Chang-Yu Hsieh +1
Ground-state preparation for a given Hamiltonian is a common quantum-computing task of great importance and has relevant applications in quantum chemistry, computational material m…
Classification on the Computational Complexity of Spin Models
Shi-Xin Zhang
In this note, we provide a unifying framework to investigate the computational complexity of classical spin models and give the full classification on spin models in terms of syste…
Automatic Differentiation for Complex Valued SVD
Zhou-Quan Wan, Shi-Xin Zhang
In this note, we report the back propagation formula for complex valued singular value decompositions (SVD). This formula is an important ingredient for a complete automatic differ…
Strong and Weak Many-Body Localizations
Shi-Xin Zhang, Hong Yao
Many aspects of many-body localization (MBL), including dynamic classification of MBL phases, remain elusive. Here, by performing real-space renormalization group (RSRG) analysis w…
Universal properties of many-body localization transitions in quasiperiodic systems
Shi-Xin Zhang, Hong Yao
Precise nature of MBL transitions in both random and quasiperiodic (QP) systems remains elusive so far. In particular, whether MBL transitions in QP and random systems belong to th…
