Statistics of radiation at Josephson parametric resonance
Ciprian Padurariu, Fabian Hassler, Yuli V. Nazarov
Motivated by recent experiments, we study theoretically the full counting statistics of radiation emitted below the threshold of parametric resonance in a Josephson junction circui…
Coulomb-assisted braiding of Majorana fermions in a Josephson junction array
B. van Heck, A. R. Akhmerov, F. Hassler +2
We show how to exchange (braid) Majorana fermions in a network of superconducting nanowires by control over Coulomb interactions rather than tunneling. Even though Majorana fermion…
Selection rules for Raman-active electronic excitations in carbon nanotubes
Oleksiy Kashuba, Vladimir I. Fal'ko
Raman measurements in carbon allotropes are generally associated with the exploration of the vibrational modes. Here, we present a theory of the non-resonant inelastic light scatte…
Time scales in the dynamics of an interacting quantum dot
L. Debora Contreras-Pulido, Janine Splettstoesser, Michele Governale +2
We analyze the dynamics of a single-level quantum dot with Coulomb interaction, weakly tunnel coupled to an electronic reservoir, after it has been brought out of equilibrium, e.g.…
Charge detection in a bilayer graphene quantum dot
Stefan Fringes, Christian Volk, Caroline Norda +5
We show measurements on a bilayer graphene quantum dot with an integrated charge detector. The focus lies on enabling charge detection with a 30 nm wide bilayer graphene nanoribbon…
Tunable capacitive inter-dot coupling in a bilayer graphene double quantum dot
Stefan Fringes, Christian Volk, Bernat Terrés +4
We report on a double quantum dot which is formed in a width-modulated etched bilayer graphene nanoribbon. A number of lateral graphene gates enable us to tune the quantum dot ener…
Readout of carbon nanotube vibrations based on spin-phonon coupling
Christoph Ohm, Christoph Stampfer, Janine Splettstoesser +1
We propose a scheme for spin-based detection of the bending motion in suspended carbon-nanotubes, using the curvature-induced spin-orbit interaction. We show that the resulting eff…
Single-particle interference versus two-particle collisions
Stefan Juergens, Janine Splettstoesser, Michael Moskalets
We consider a mesoscopic circuit in the quantum Hall effect regime comprising two synchronized single-particle sources emitting particles into a Mach-Zehnder interferometer. While…
Nonlinear adiabatic response of interacting quantum dots
Oleksiy Kashuba, Herbert Schoeller, Janine Splettstoesser
We develop a generic method in Liouville space to describe the dissipative dynamics of coherent interacting quantum dots with adiabatic time dependence beyond linear response. We s…

L. E. F. Foa Torres, H. L. Calvo, C. G. Rocha +1
We present a theoretical study of quantum charge pumping with a single ac gate applied to graphene nanoribbons and carbon nanotubes operating with low resistance contacts. By combi…
Adiabatic pumping in a double-dot Cooper-pair beam splitter
Bastian Hiltscher, Michele Governale, Janine Splettstoesser +1
We study adiabatic pumping through a double quantum dot coupled to normal and superconducting leads. For this purpose a perturbation expansion in the tunnel coupling between the do…
Conversion of self-assembled monolayers into nanocrystalline graphene: Structure and electric transport
Andrey Turchanin, Dirk Weber, Matthias Buenfeld +7
Graphene-based materials have been suggested for applications ranging from nanoelectronics to nanobiotechnology. However, the realization of graphene-based technologies will requir…

Andrey Turchanin, Andre Beyer, Christoph Nottbohm +7
We present a new route for the fabrication of ultrathin (~1 nm) carbon films and membranes, whose electrical behavior can be tuned from insulating to conducting. Self-assembled mon…
Tuning laser-induced bandgaps in graphene
Hernan L. Calvo, Horacio M. Pastawski, Stephan Roche +1
Could a laser field lead to the much sought-after tunable bandgaps in graphene? By using Floquet theory combined with Green's functions techniques, we predict that a laser field in…

We investigate etched single-layer graphene nanoribbons with different widths ranging from 30 to 130 nm by confocal Raman spectroscopy. We show that the D-line intensity only depen…
Nonequilibrium phonon backaction on the current noise in atomic-sized junctions
Tomas Novotny, Federica Haupt, Wolfgang Belzig
We study backaction effects of phonon heating due to tunneling electrons on the current noise in atomic-sized junctions. Deriving a generalized kinetic approximation within the ext…
