Superconductivity and competing orders in honeycomb $t$ - $J$ model: interplay of lattice geometry and next-nearest-neighbor hopping

Zhi Xu, Hong-Chen Jiang, Yi-Fan Jiang

We investigate the extended $t$ - $J$ model on honeycomb lattices with next-nearest-neighbor (NNN) electron hopping $t^{'}$ and superexchange coupling $J^{'} = (t^{'} / t)^{2} J$ using large-scale…

Pair density wave, infinite-length stripes, and holon Wigner crystal in single-band Hubbard model on diagonal square lattice

Zhi Xu, Gui-Xin Liu, Yi-Fan Jiang

We employ large-scale density-matrix renormalization group (DMRG) simulations to investigate the quantum phase diagram of the hole-doped Hubbard model on square lattices. By implem…

Superconductivity enhancement and particle-hole asymmetry: interplay with electron attraction in doped Hubbard model

Zhi Xu, Hong-Chen Jiang, Yi-Fan Jiang

The role of near-neighbor electron attraction $V$ in strongly correlated systems has been at the forefront of recent research of unconventional superconductivity. However, its impl…
