Dirac-semimetal phase diagram of two-dimensional black phosphorus
Hyeonjin Doh, Hyoung Joon Choi
Black phosphorus (BP), a layered van der Waals material, reportedly has a band gap sensitive to external perturbations and manifests a Dirac-semimetal phase when its band gap is cl…
Analytic approach to the edge state of the Kane-Mele Model
Hyeonjin Doh, Gun Sang Jeon, Hyoung Joon Choi
We investigate the edge state of a two-dimensional topological insulator based on the Kane-Mele model. Using complex wave numbers of the Bloch wave function, we derive an analytica…
Bifurcation of the Edge-State Width in the Two-Dimensional Topological Insulator
Hyeonjin Doh, Gun Sang Jeon
We examine the properties of edge states in a two-dimensional topological insulator. Based on the Kane-Mele model, we derive two coupled equations for the energy and the effective…
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…
Meta-nematic transitions in a bilayer system: Application to the bilayer ruthenate
Christoph Puetter, Hyeonjin Doh, Hae-Young Kee
It was suggested that the two consecutive metamagnetic transitions and the large residual resistivity discovered in SrRuO can be understood via the nematic order and it…
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…
