Competing $s$ -wave pairing in overdoped $t$ - $J$ model

Wayne Zheng, Tao Cheng, Zheng-Yuan Yue +3

The $d$ -wave pairing symmetry has long been considered a defining feature of high-temperature superconductivity in cuprates. In this work, we reveal that $s$ -wave pairing states ex…

Evolution from intralayer to interlayer superconductivity in a bilayer $t$ - $J$ model

Yuan Yang, Xin Lu, Yuan Wan +2

Motivated by the bilayer cuprate superconductors and nickelate superconductor La $_{3}$ Ni $_{2}$ O $_{7}$ , we investigate the evolution from intralayer to interlayer superconductivity based…

$Z_{2}$ order fractionalization, topological phase transition, and odd frequency pairing in an exactly solvable spin-charge ladder

Jian-Jian Miao, Wei-Qiang Chen

Motivated by the order fractionalization in Kitaev-Kondo model, we propose an exactly solvable spin-charge ladder model to study the order fractionalization with discrete symmetry.…
