Sixfold fermion near the Fermi level in cubic PtBi2

open access: yesSciPost Physics, 2021
We show that the cubic compound PtBi2, is a topological semimetal hosting a sixfold band touching point in close proximity to the Fermi level. Using angle-resolved photoemission spectroscopy, we map the bandstructure of the system, which is in good ...

Adsorption/desorption and electrically controlled flipping of ammonia molecules on graphene [PDF]

open access: yes, 2010
In this paper, we evaluate of the adsorption/ desorption of ammonia molecules on a graphene surface by studying the Fermi level shift. Based on a physically plausible model, the adsorption and desorption rates of ammonia molecules on graphene have been ...

Asymptotic Pomeranchuk instability of Fermi liquids in half-filled Landau levels

open access: yesScientific Reports, 2023
We present a theory of spontaneous Fermi surface deformations for half-filled Landau levels (filling factors of the form $$\nu =2 \, n+1/2$$ ν = 2 n + 1 / 2 ).

Giant anomalous Nernst effect in the Co2MnAl1−xSix Heusler alloy induced by Fermi level tuning and atomic ordering [PDF]

open access: yesPhysical review B, 2019
Co2MnAl has been predicted to have Weyl points near Fermi level which is expected to give rise to exotic transverse transport properties such as large anomalous Hall(AHE) and Nernst effects(ANE) due to large Berry curvature.

Topological Type-II Dirac Fermions Approaching the Fermi Level in a Transition Metal Dichalcogenide NiTe2 [PDF]

open access: yes, 2018
Type-II Dirac/Weyl semimetals are characterized by strongly tilted Dirac cones such that the Dirac/Weyl node emerges at the boundary of electron and hole pockets as a new state of quantum matter, distinct from the standard Dirac/Weyl points with a point ...
