Wave-function-based approach to quasiparticle bands: new insight into the electronic structure of c-ZnS
A. Stoyanova, L. Hozoi, P. Fulde +1
Ab initio wave-function-based methods are employed for the study of quasiparticle energy bands of zinc-blende ZnS, with focus on the Zn 3d "semicore" states. The relative energies…
Smooth concordance of links topologically concordant to the Hopf link
Jae Choon Cha, Taehee Kim, Daniel Ruberman +1
It was shown by Jim Davis that a 2-component link with Alexander polynomial one is topologically concordant to the Hopf link. In this paper, we show that there is a 2-component lin…
Realizability of Polytopes as a Low Rank Matrix Completion Problem
Michael Gene Dobbins
This article gives necessary and sufficient conditions for a relation to be the containment relation between the facets and vertices of a polytope. Also given here, are a set of ma…
Quark Number Susceptibility with Finite Quark Mass in Holographic QCD
Kyung-il Kim, Youngman Kim, Shingo Takeuchi +1
We study the effect of a finite quark mass on the quark number susceptibility in the framework of holographic QCD. We work in a bottom-up model with a deformed AdS black hole and D…
Electronic topological transition in sliding bilayer graphene
Young-Woo Son, Seon-Myeong Choi, Yoon Pyo Hong +2
We demonstrate theoretically that the topology of energy bands and Fermi surface in bilayer graphene undergoes a very sensitive transition when extremely tiny lateral interlayer sh…
Spin Transfer Torque and Tunneling Magnetoresistance Dependences on the Finite Bias Voltages and Insulator Barrier Energy
Chun-Yeol You, Jae-Ho Han, Hyun-Woo Lee
We investigate the dependence of perpendicular and parallel spin transfer torque (STT) and tunneling magnetoresistance (TMR) on the insulator barrier energy in the magnetic tunnel…
Scaling and non-Abelian signature in fractional quantum Hall quasiparticle tunneling amplitude
Zi-Xiang Hu, Ki Hoon Lee, E. H. Rezayi +2
We study the scaling behavior in the tunneling amplitude when quasiparticles tunnel along a straight path between the two edges of a fractional quantum Hall annulus. Such scaling b…
Electrical transport through a mechanically gated molecular wire
C. Toher, R. Temirov, A. Greuling +5
A surface-adsorbed molecule is contacted with the tip of a scanning tunneling microscope (STM) at a pre-defined atom. On tip retraction, the molecule is peeled off the surface. Dur…
Efficient linear scaling method for computing the thermal conductivity of disordered materials
Wu Li, Haldun Sevincli, Stephan Roche +1
An efficient order real-space Kubo approach is developed for the calculation of the thermal conductivity of complex disordered materials. The method, which is based on the Cheb…
Direction Dependence of Spin Relaxation in Confined 2D Systems
Paul Wenk, Stefan Kettemann
The dependence of spin relaxation on the direction of the quantum wire under Rashba and Dresselhaus (linear and cubic) spin orbit coupling is studied. Comprising the dimensional re…
