Quantized Conductance through Surface States in High Quality Three-Dimensional Dirac Semimetal CdAs Nanowire/Nanoribbon p-n Junctions
Sungjin An, Zhuo Bin Siu, Vardan Kaladzhyan +8
We report the observation of quantized conductance in high-mobility three-dimensional Dirac semimetal CdAs nanowire and nanoribbon p-n junctions. By employing suspended dev…
RKKY interaction at helical edges of topological superconductors
Katharina Laubscher, Dmitry Miserev, Vardan Kaladzhyan +2
We study spin configurations of classical magnetic impurities placed close to the edge of a two-dimensional topological superconductor both analytically and numerically. First, we…
Quasiparticle interference patterns in bilayer graphene with trigonal warping
Vardan Kaladzhyan, Frédéric Joucken, Zhehao Ge +5
We calculate the form of quasiparticle interference patterns in bilayer graphene within a low-energy description, taking into account perturbatively the trigonal warping terms. We…
Surface states and quasiparticle interference in Bernal and rhombohedral graphite with and without trigonal warping
Vardan Kaladzhyan, Sarah Pinon, Frédéric Joucken +6
We use an exact analytical technique [Phys. Rev. B \textbf{101}, 115405 (2020), Phys. Rev. B \textbf{102}, 165117 (2020)] to recover the surface Green's functions for Bernal (ABA)…
Direct Visualization of Native Defects in Graphite and Their Effect on the Electronic Properties of Bernal-Stacked Bilayer Graphene
Frederic Joucken, Cristina Bena, Zhehao Ge +7
Graphite crystals used to prepare graphene-based heterostructures are generally assumed to be defect free. We report here scanning tunneling microscopy results that show graphite c…
Surface Green's functions and quasiparticle interference in Weyl semimetals
Sarah Pinon, Vardan Kaladzhyan, Cristina Bena
We use the exact analytical technique introduced in Phys. Rev. B 101, 115405 to recover the surface Green's functions and the corresponding Fermi-arc surface states for various lat…
