Sign structure of the $t$ - $t^{'}$ - $J$ model and its physical consequences

Xin Lu, Jia-Xin Zhang, Shou-Shu Gong +2

Understanding the doped Mott insulator is a central challenge in condensed matter physics. In this work, we first explicitly identify a new sign structure in the $t$ - $t^{'}$ - $J$ model…

Crossover from Fermi Arc to Full Fermi Surface

Jia-Xin Zhang, Zheng-Yu Weng

The Fermi surface as a contour of the gapless quasiparticle excitation in momentum space is studied based on a mean-field theory of the doped Mott insulator, where the underlying p…
