Remote Mesoscopic Signatures of Induced Magnetic Texture in Graphene

N. Arabchigavkani, R. Somphonsane, H. Ramamoorthy +15

Mesoscopic conductance fluctuations are a ubiquitous signature of phase-coherent transport in small conductors, exhibiting universal character independent of system details. In thi…

Simulated TEM imaging of a heavily irradiated metal

D. R. Mason, M. Boleininger, J. Haley +4

We recast the Howie-Whelan equations for generating simulated transmission electron microscope (TEM) images, replacing the dependence on local atomic displacements with atomic posi…

Chiral electronic excitations and strong electron-phonon coupling to Weyl fermions in the Kagome semimetal CoSnS

G. He, M. Kute, Z. C. Xu +10

We present results of a Raman scattering study of the Kagome ferromagnet CoSnS, with a focus on electronic and phononic excitations and their interplay. We provide a th…

Comparison of dynamical and equilibrium surface spin-reorientations: Inferences on the nature of the phase transitions in the presence of dipole interactions

G. He, R. Belanger, P. H. Hguyen +1

The influence of long-range dipole interactions on two dimensional magnetism has been studied extensively in the spin-reorientation transition of ferromagnetic ultrathin films. Alt…

Voltage-induced suppression of weak localization in graphene

J. Fransson, R. Somphonsane, H. Ramamoorthy +2

In this theoretical study, we explore the manner in which the quantum correction due to weak localization is suppressed in weakly-disordered graphene, when it is subjected to the a…

Universal voltage scaling due to self-averaging of the quantum corrections in graphene

R. Somphonsane, H. Ramamoorthy, G. He +9

The differential conductance of graphene is shown to exhibit a zero-bias anomaly at low temperatures, arising from a suppression of the quantum corrections due to weak localization…
