Efficient simulation of infinite tree tensor network states on the Bethe lattice
Wei Li, Jan von Delft, Tao Xiang
We show that the simple update approach proposed by Jiang et. al. [H.C. Jiang, Z.Y. Weng, and T. Xiang, Phys. Rev. Lett. 101, 090603 (2008)] is an efficient and accurate method for…
Green functions and correlation functions of a solvable S=1 quantum Ising spin model with dimerization
Zhi-Hua Yang, Li-Ping Yang, Hai-Na Wu +2
This is a supplementary material of our recent paper\cite{yangPRB}, where a class of exactly solvable S=1 quantum Ising spin models were studied based on the hole decomposition sch…
Exact solutions of a class of S=1 quantum Ising spin models
Zhi-Hua Yang, Li-Ping Yang, Hai-Na Wu +2
We propose a hole decomposition scheme to exactly solve a class of spin-1 quantum Ising models with transverse or longitudinal single-ion anisotropy. In this scheme, the spin-1 mod…
Density matrix renormalization group study of a quantum impurity model with Landau-Zener time-dependent Hamiltonian
Cheng Guo, Andreas Weichselbaum, Stefan Kehrein +2
We use the adaptive time-dependent density matrix renormalization group method (t-DMRG) to study the nonequilibrium dynamics of a benchmark quantum impurity system which has a time…
Universal linear-temperature dependence of static magnetic susceptibility in iron-pnictides
Guang-Ming Zhang, Yue-Hua Su, Zhong-Yi Lu +3
A universal linear-temperature dependence of the uniform magnetic susceptibility has been observed in the nonmagnetic normal state of iron-pnictides. This non-Pauli and non-Curie-W…
Maximized string order parameters in the valence bond solid states of quantum integer spin chains
Hong-Hao Tu, Guang-Ming Zhang, Tao Xiang
We propose a set of maximized string order parameters to describe the hidden topological order in the valence bond solid states of quantum integer spin-S chains. These optimized st…
