Dynamical non-ergodic scaling in continuous finite-order quantum phase transitions
Shusa Deng, Gerardo Ortiz, Lorenza Viola
We investigate the emergence of universal dynamical scaling in quantum critical spin systems adiabatically driven out of equilibrium, with emphasis on quench dynamics which involve…
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…
