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…
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…
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…
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…
Dynamical Spectra of Spin Supersolid States in Triangular Antiferromagnets
Runze Chi, Jiahang Hu, Hai-Jun Liao +1
We employ tensor network renormalization to explore the dynamical spectra of the easy-axis triangular-lattice antiferromagnet (TLAF) in a magnetic field. Our analysis identifies tw…
