Topological and Trivial Valence-Bond Orders in Higher-Spin Kitaev Models
Xing-Yu Zhang, Qi Yang, Philippe Corboz +2
We investigate the quantum phases of higher-spin Kitaev models using tensor network methods. Our results reveal distinct bond-ordered phases for spin-1, spin-, and sp…
Efficient iPEPS Simulation on the Honeycomb Lattice via QR-based CTMRG
Qi Yang, Philippe Corboz
We develop a QR-based corner transfer matrix renormalization group (CTMRG) framework for contracting infinite projected entangled-pair states (iPEPS) on honeycomb lattices. Our met…
Hydrodynamics of ultralight complex scalar field dark matter and its impact on the growth of structure
Qi Yang, Bohua Li, Paul R. Shapiro
The mass window of ultralight axion dark matter motivated by suppressing the growth of structure on subgalactic scales, , is now severely constrained b…
Alternating and Gaussian fermionic Isometric Tensor Network States
Yantao Wu, Zhehao Dai, Sajant Anand +5
Isometric tensor networks in two dimensions enable efficient and accurate study of quantum many-body states, yet the effect of the isometric restriction on the represented quantum…
Real-space recipes for general topological crystalline states
Zhida Song, Chen Fang, Yang Qi
Topological crystalline states are short-range entangled states jointly protected by onsite and crystalline symmetries. While the non-interacting limit of these states, e.g., the t…
