The Role of Chaos in One-Dimensional Heat Conductivity
Jun-Wen Mao, You-Quan Li, Yong-Yun Ji
We investigate the heat conduction in a quasi 1-D gas model with various degree of chaos. Our calculations indicate that the heat conductivity is independent of system size whe…
Entanglement of degenerate ground state for spin 1 and 1/2 pair
You-Quan Li, Guo-Qiang Zhu, Xue-An Zhao
We study the entanglement feature of the ground state of a system composed of spin 1 and 1/2 parts. The concurrence vector is shown to be consistent with the measurement of von Neu…
Medium effects on the selection of sequences folding into stable proteins in a simple model
You-Quan Li, Yong-Yun Ji, Jun-Wen Mao +1
We study the medium effects on the selection of sequences in protein folding by taking account of the surface potential in HP-model. Our analysis on the proportion of H and P monom…
Charge Ordered RVB States in the Doped Cuprates
Huai-Xiang Huang, You-Quan Li, Fu-Chun Zhang
We study charge ordered d-wave resonating valence bond states (dRVB) in the doped cuprates, and estimate the energies of these states in a generalized model by using a renor…
On the ground state and excitations of a four-component fermion model
You-Quan Li, Guan-Shan Tian, Michael Ma +1
The properties of the ground state and excitations of a four-component Hubbard-like model are studied by the Lieb-Schultz-Mattis approach. It is proven rigorously that the ground s…
Entanglement and quantum phase transition in the extended Hubbard model
Shi-Jian Gu, Shu-Sa Deng, You-Quan Li +1
We study quantum entanglement in one-dimensional correlated fermionic system. Our results show, for the first time, that entanglement can be used to identify quantum phase transiti…
