Title: Universality vs materials-dependence in cuprates: ARPES studies
of the model cuprate Hg1201
Abstract: The cuprate superconductors exhibit the highest
ambient-pressure superconducting transition temperatures (T c ), and
after more than three decades of extraordinary research activity,
continue to pose formidable scientific challenges. A major
experimental obstacle has been to distinguish universal phenomena from
materials- or technique-dependent ones. Angle-resolved photoemission
spectroscopy (ARPES) measures momentum-dependent single-particle
electronic excitations and has been invaluable in the endeavor to
determine the anisotropic momentum-space properties of the cuprates.
HgBa 2 CuO 4+d (Hg1201) is a single-layer cuprate with a particularly
high optimal T c and a simple crystal structure; yet there exists
little information from ARPES about the electronic properties of this
model system. I will present recent ARPES studies of doping-,
temperature-, and momentum-dependent systematics of near-nodal
dispersion anomalies in Hg1201. The data reveal a hierarchy of three
distinct energy scales which establish several universal phenomena,
both in terms of connecting multiple experimental techniques for a
single material, and in terms of connecting comparable spectral
features in multiple structurally similar cuprates.
