Gap anisotropy in the angle-resolved photoemission spectroscopy of Bi_2Sr_2CaCu_2O_{8+δ}

Tulika Maitra, A. Taraphder

The gap anisotropy in Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ is revisited in the framework of a d-wave scenario in view of the recent angle-resolved photoemission experiment. Based on a tig…
