Concerning two-gap ARPES data, the pseudogap, 2-q striping and magnetc circular dichroism from the negative-U HTSC perspective

Abstract

Recent photoemission work on underdoped cuprates between Tc and T*, the pseudogap temperature, are interpreted within the framework of a previously developed negative-U scenario. From this exposition, incorporating a developed 2q diagonal striping model, detailed understanding follows of the ARPES results, together with certain STM and far infrared optical data. Identification of the origin of the magnetic circular dichroism and related effects exhibited by such materials below T* also appears to have been achieved.
