Block-block entanglement and quantum phase transitions in one-dimensional extended Hubbard model
Shu-Sa Deng, Shi-Jian Gu, Hai-Qing Lin
In this paper, we study block-block entanglement in the ground state of one-dimensional extended Hubbard model. Our results show that the phase diagram derived from the block-block…
Fermionic concurrence in the extended Hubbard dimer
Shu-Sa Deng, Shi-Jian Gu, Hai-Qing Lin
In this paper, we introduce and study the fermionic concurrence in a two-site extended Hubbard model. Its behaviors both at the ground state and finite temperatures as function of…
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…
Local entanglement and quantum phase transition in the Hubbard model
Shi-Jian Gu, You-Quan Li, Hai-Qing Lin
The local entanglement of the one-dimensional Hubbard model is studied on the basis of its Bethe-ansatz solution. The relationship between the local entanglement and the on-s…
