Optimized Tensor-Network Renormalization for Quantum Dynamics: Resolving the Spectral Function of
Jiahang Hu, Runze Chi, B. Normand +2
Tensor-network methods have opened a powerful route for the study of dynamical spectral functions in two-dimensional quantum systems. However, existing approaches within the framew…
Exact Neural-Network Representations of the Motzkin States
Runde Zha, Yuntian Gu, Chaohui Fan +3
Motzkin spin chains are paradigmatic frustration-free one-dimensional quantum systems whose ground states feature exactly solvable combinatorial structures and exotic, area-law-vio…
Statistical mechanics of the -queens problem
Zong-Yue Liu, Hai-Jun Liao, Lei Wang
We investigate the -queens problem as a lattice gas -- a model in which queens are placed on an chessboard with pairwise repulsive interactions along shared row…
Dynamical Spectral Function of the Kagome Quantum Spin Liquid
Jiahang Hu, Runze Chi, Yibin Guo +3
Quantum spin liquids (QSLs) host exotic fractionalized magnetic and gauge-field excitations whose microscopic origins and experimental verification remain frustratingly elusive. In…
Possible Observation of Quadrupole Waves in Spin Nematics
Jieming Sheng, Jiahang Hu, Lei Xu +15
Discovery of new states of matter is a key objective in modern condensed matter physics, which often leads to revolutionary technological advancements such as superconductivity. Qu…
Thermodynamics of the Hubbard Model on the Bethe Lattice
Jia-Lin Chen, Zhen Fan, Bo Zhan +6
We investigate the thermodynamic properties of the Hubbard model on the Bethe lattice with a coordination number of 3 using the thermal canonical tree tensor network method. Our fi…
