Transfer-matrix functions for algebraically decaying interactions in variational infinite matrix product states
Qi Yang
Variational infinite matrix product state (iMPS) calculations usually make Hamiltonians with algebraically decaying interactions compatible with standard MPO algorithms by first re…
Stringy Effects on Holographic Complexity: The Complete Volume in Dynamical Spacetimes
Qi Yang, Yu-Xiao Liu
We investigate the stringy effects on holographic complexity in -dimensional Gauss-Bonnet gravity using the ``complete volume'' proposal for higher-curvature theories. Our a…
Accelerating two-dimensional tensor network contractions using QR decompositions
Yining Zhang, Qi Yang, Philippe Corboz
Infinite projected entangled-pair states (iPEPS) provide a powerful tool for studying strongly correlated systems directly in the thermodynamic limit. A core component of the algor…
Accelerating two-dimensional tensor network optimization by preconditioning
Xing-Yu Zhang, Qi Yang, Philippe Corboz +2
We revisit gradient-based optimization for infinite projected entangled pair states (iPEPS), a tensor network ansatz for simulating many-body quantum systems. This approach is hind…
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…
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…
