Intimate relations between electronic nematic, d-density wave and d-wave superconducting states
Hae-Young Kee, Hyeonjin Doh, Thomas Grzesiak
This paper consists of two important theoretical observations on the interplay between l = 2 condensates; d-density wave (ddw), electronic nematic and d-wave superconducting states…

A Direct Probe of Electronic Nematic Order; Symmetry Information in Scanning Tunneling Microscope Images
Hyeonjin Doh, Hae-Young Kee
An electronic nematic state spontaneously breaks a point-group symmetry of an underlying lattice. As a result, the nematic-isotropic transition accompanies a Fermi surface distorti…

Study of Harper's Equation for the 2-D Systems of Antiferromagnetically Correlated Electrons in an External Magnetic Field
Seung-Pyo Hong, Hyeonjin Doh, Sung-Ho Suck Salk
Considering interacting (antiferromagnetically correlated) electrons, we derive a generalized Harper's equation for the square lattice of infinite size. We obtain an analytic expre…
