Journal ArticleDOI
Sub-Poissonian Shot Noise in Graphene
TL;DR: It is found that the minimum conductivity of order e2/h at the Dirac point (when the electron and hole excitations are degenerate) is associated with a maximum of the Fano factor (the ratio of noise power and mean current).
Journal ArticleDOI
Single valley Dirac fermions in zero-gap HgTe quantum wells
B. Büttner,Chao-Xing Liu,Grigory Tkachov,E. G. Novik,C. Brüne,Hartmut Buhmann,Ewelina M. Hankiewicz,Patrik Recher,Björn Trauzettel,Shou-Cheng Zhang,Laurens W. Molenkamp +10 more
TL;DR: In this paper, the cone-like nature of the points in 2D HgTe quantum wells, where conduction and valance bands meet, has been investigated and shown to have similar properties to the spin-and valley-degeneracy of graphene.
Journal ArticleDOI
Bound states and magnetic field-induced valley splitting in gate-tunable graphene quantum dots
TL;DR: In this article, the magnetic field dependence of energy levels in gapped single-layer and bilayer graphene quantum dots (QDs) defined by electrostatic gates is studied analytically in terms of the Dirac equation.
Journal ArticleDOI
Decaying spectral oscillations in a Majorana wire with finite coherence length
TL;DR: In this paper, the authors investigated the excitation energy of a proximitized Rashba wire in the presence of a position dependent pairing and found three parameter ranges with different spectral properties: crossings, anticrossings, and asymptotic reduction of the energy as a function of the applied Zeeman field.
Journal ArticleDOI
Shot-noise detection in a carbon nanotube quantum dot.
Eugen Onac,Franck Balestro,Björn Trauzettel,Björn Trauzettel,C. F. J. Lodewijk,Leo P. Kouwenhoven +5 more
TL;DR: An on-chip detection scheme for high frequency signals is used to detect noise generated by a quantum dot formed in a single wall carbon nanotube based on photon assisted tunneling in a superconductor-insulator-superconductor junction.
