Phase Diagram, $d$ -Wave Superconductivity, and Pseudogap of the $t$ - $t^{'}$ - $J$ Model at Finite Temperature

Dai-Wei Qu, Qiaoyi Li, Shou-Shu Gong +3

Recently, robust $d$ -wave superconductive (SC) order has been unveiled in the ground state of the 2D $t$ - $t^{'}$ - $J$ model -- with both nearest-neighbor ( $t$ ) and next-nearest-neighbo…

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…
