Twisted Hubbard Model for Sr2IrO4: Magnetism and Possible High Temperature Superconductivity
Twisted Hubbard Model for Sr2IrO4 Magnetism Possible High Temperature Superconductivity
2010/11/23
Sr2IrO4 has been suggested as a Mott insulator from a single Jeff = 1/2 band, similar to the
cuprates. However this picture is complicated by the measured large magnetic anisotropy and
ferromagnetis...
Personal history of my engagement with cuprate superconductivity, 1986-2010
Personal history cuprate superconductivity
2010/11/22
Six months ago I was asked to write a personal history of my engagement with the high-Tc problem of the cuprate superconductors, in rather informal and autobiographical style. As the work proceeded I ...
Effect of charge ordering on superconductivity in high-temperature superconductors
charge ordering high-temperature superconductors
2010/11/19
It is shown that charge ordering in layered crystalline metals causes an increase in the normal
state energy of the conducting layers. If this increase in the energy exceeds the difference between th...
