A simple phenomenological model for describing the normal state single particle spectral function of high temperature superconductors
Kazue Matsuyama, Rohit Dilip, G. -H. Gweon
Describing the normal state single particle spectral function line shapes of high temperature superconductors remains an important goal in condensed matter physics. Recently, we ha…
A spectroscopic fingerprint of electron correlation in high temperature superconductors
G. -H. Gweon, G. -D. Gu, J. Schneeloch +2
The so-called "strange metal phase" [1] of high temperature (high Tc) superconductors remains at the heart of the high Tc mystery. Better experimental data and insightful theoretic…
Phenomenological model for the normal state ARPES line shapes of high temperature superconductors
Kazue Matsuyama, G. -H. Gweon
Fully describing the single particle spectral function observed for high temperature superconduc- tors in the normal state is an important goal, yet unachieved. Here, we present a…
Extremely Correlated Fermi Liquid Description of Normal State ARPES in Cuprates
G. -H. Gweon, B. S. Shastry, G. D. Gu
The normal state single particle spectral function of the high temperature superconducting cuprates, measured by the angle resolved photoelectron spectroscopy (ARPES), has been con…
Momentum-space electronic structures and charge orders of high-temperature superconductors Ca2-xNaxCuO2Cl2 and Bi2Sr2CaCu2O8+delta
Jianqiao Meng, M. Brunner, K. -H. Kim +6
We study the electronic structure of Ca2-xNaxCuO2Cl2 and Bi2Sr2CaCu2O8+d samples in a wide range of doping, using angle-resolved photoemission spectroscopy, with emphasis on on the…
Substrate-induced band gap opening in epitaxial graphene
S. Y. Zhou, G. -H. Gweon, A. V. Fedorov +6
