The Virial Theorem in Graphene and other Dirac Materials
J. Dustan Stokes, Hari P. Dahal, Alexander V. Balatsky +1
The virial theorem is applied to graphene and other Dirac Materials for systems close to the Dirac points where the dispersion relation is linear. From this, we find the exact form…
An Interactive 3D Visualization Tool for Large Scale Data Sets for Quantitative Atom Probe Tomography
Hari Dahal, Michael Stukowski, Matthias J. Graf +2
Several visualization schemes have been developed for imaging materials at the atomic level through atom probe tomography. The main shortcoming of these tools is their inability to…
Visualization of nano-plasmons in graphene
Hari Dahal, Rodrigo A. Muniz, Stephan Haas +2
We study localized plasmons at the nanoscale (nano-plasmons) in graphene. The collective excitations of induced charge density modulations in graphene are drastically changed in th…
The glassy response of double torsion oscillators in solid Helium-4
Matthias J. Graf, Jung-Jung Su, Hari P. Dahal +2
Single and double torsion oscillators have been used successfully to measure the anomalous change in resonant frequency and accompanying dissipation in solid He-4. We present a gla…
Impurity assisted nanoscale localization of plasmonic excitations in graphene
Rodrigo A. Muniz, Hari P. Dahal, A. V. Balatsky +1
The plasmon modes of pristine and impurity doped graphene are calculated, using a real-space theory which determines the non-local dielectric response within the random phase appro…
Theory of Fano Resonances in Graphene: The Kondo effect probed by STM
T. O. Wehling, H. P. Dahal, A. I. Lichtenstein +3
We consider the theory of Kondo effect and Fano factor energy dependence for magnetic impurity (Co) on graphene. We have performed a first principles calculation and find that the…
