Features due to spin-orbit coupling in the optical conductivity of single-layer graphene
P. Ingenhoven, J. Z. Bernad, U. Zuelicke +1
We have calculated the optical conductivity of a disorder-free single graphene sheet in the presence of spin-orbit coupling, using the Kubo formalism. Both intrinsic and structural…
Anomalous Josephson current through a spin-orbit coupled quantum dot
A. Zazunov, R. Egger, T. Jonckheere +1
For a general model of a mesoscopic multi-level quantum dot, we determine the necessary conditions for the existence of an anomalous Josephson current with spontaneously broken tim…
Josephson effect for SU(4) carbon nanotube quantum dots
A. Zazunov, A. Levy Yeyati, R. Egger
We present the theory of the Josephson effect in nanotube dots where an SU(4) symmetry can be realized. We find a remarkably rich phase diagram that significantly differs from the…
Critical Josephson current through a bistable single-molecule junction
Andreas Schulz, Alex Zazunov, Reinhold Egger
We compute the critical Josephson current through a single-molecule junction. As a model for a molecule with a bistable conformational degree of freedom, we study an interacting si…
Phonon-phonon interactions and phonon damping in carbon nanotubes
A. De Martino, R. Egger, A. O. Gogolin
We formulate and study the effective low-energy quantum theory of interacting long-wavelength acoustic phonons in carbon nanotubes within the framework of continuum elasticity theo…
Spin transport and bipolaron density in organic polymers
P. Ingenhoven, R. Egger, U. Zülicke
We present a theory for spin-polarized transport through a generic organic polymer connected to ferromagnetic leads with arbitrary angle theta between their magnetization direction…
