Biexciton recombination rates in self-assembled quantum dots

- M. Wimmer, S. Nair, J. Shumway
- Physics
- 23 December 2005

The radiative recombination rates of interacting electron-hole pairs in a quantum dot are strongly affected by quantum correlations among electrons and holes in the dot. Recent measurements of the… Expand

Quantum point contact as a probe of a topological superconductor

- M. Wimmer, A. Akhmerov, J. Dahlhaus, C. Beenakker
- Physics
- 30 January 2011

We calculate the conductance of a ballistic point contact to a superconducting wire, produced by the s-wave proximity effect in a semiconductor with spin–orbit coupling in a parallel magnetic field.… Expand

Symmetry classes in graphene quantum dots: universal spectral statistics, weak localization, and conductance fluctuations.

- J. Wurm, A. Rycerz, I. Adagideli, M. Wimmer, K. Richter, H. Baranger
- Medicine, Physics
- Physical review letters
- 7 August 2008

We study the symmetry classes of graphene quantum dots, both open and closed, through the conductance and energy level statistics. For abrupt termination of the lattice, these properties are well… Expand

Spin currents in rough graphene nanoribbons: universal fluctuations and spin injection.

- M. Wimmer, I. Adagideli, S. Berber, D. Tománek, K. Richter
- Physics, Medicine
- Physical review letters
- 20 September 2007

We investigate spin conductance in zigzag graphene nanoribbons and propose a spin injection mechanism based only on graphitic nanostructures. We find that nanoribbons with atomically straight,… Expand

A zero-voltage conductance peak from weak antilocalization in a Majorana nanowire

- D. Pikulin, J. Dahlhaus, M. Wimmer, H. Schomerus, C. Beenakker
- Physics
- 28 June 2012

We show that weak antilocalization by disorder competes with resonant Andreev reflection from a Majorana zero mode to produce a zero-voltage conductance peak of order e2/h in a superconducting… Expand

Robustness of edge states in graphene quantum dots

- M. Wimmer, A. Akhmerov, F. Guinea
- Physics
- 24 March 2010

We analyze the single particle states at the edges of disordered graphene quantum dots. We show that generic graphene quantum dots support a number of edge states proportional to circumference of the… Expand

Spin-orbit interaction in InSb nanowires

- I. V. Weperen, B. Tarasinski, +5 authors M. Wimmer
- Physics
- 2 December 2014

We use magnetoconductance measurements in dual-gated InSb nanowire devices, together with a theoretical analysis of weak antilocalization, to accurately extract spin-orbit strength. In particular, we… Expand

Andreev reflection from a topological superconductor with chiral symmetry

- M. Díez, J. Dahlhaus, M. Wimmer, C. Beenakker
- Physics
- 14 June 2012

It was pointed out by Tewari and Sau that chiral symmetry (H -> -H if e h) of the Hamiltonian of electron-hole (e-h) excitations in an N-mode superconducting wire is associated with a topological… Expand

Spin-orbit interaction in a dual gated InAs/GaSb quantum well

- A. Beukman, F. D. Vries, +12 authors L. Kouwenhoven
- Physics
- 11 April 2017

The spin-orbit interaction is investigated in a dual gated InAs/GaSb quantum well. Using an electric field, the quantum well can be tuned between a single-carrier regime with exclusively electrons as… Expand
