Strontium ruthenate (Sr$_2$RuO$_4$) has long been thought to host a spin-triplet chiral $p$-wave superconducting state. However, the singletlike response observed in recent spin-susceptibility…
Tunneling through molecules and quantum dots: Master-equation approaches
- C. Timm
- Physics
- 7 January 2008
An important class of approaches to the description of electronic transport through molecules and quantum dots is based on the master equation. We discuss various formalisms for deriving a master…
Bogoliubov Fermi surfaces: General theory, magnetic order, and topology
- P. Brydon, D. Agterberg, H. Menke, C. Timm
- PhysicsPhysical Review B
- 11 June 2018
The authors present a general theory for Fermi surfaces of Bogoliubov quasiparticles in superconductors with broken time-reversal symmetry. These Fermi surfaces form two-dimensional nodes of the…

origin appear at their surface. We show that the presence of certain inversion-type lattice symmetries can give rise to additional topological features of the gap nodes, resulting in surface states…
Time-convolutionless master equation for quantum dots: Perturbative expansion to arbitrary order
- C. Timm

convolutionless generator all divergences cancel order by order. The time-convolutionless and T-matrix master equations are contrasted to the Nakajima-Zwanzig version. The absence of divergences in…
Cotunneling through a magnetic single-molecule transistor based on N@C 60

- 21 January 2011
We present an experimental and theoretical study of a magnetic single-molecule transistor based on $\mathrm{N}@{\mathrm{C}}_{60}$ connected to gold electrodes. Particular attention is paid to the…
Noise spectra of ac-driven quantum dots: Floquet master-equation approach
We study the transport properties of a quantum dot driven by either a rotating magnetic field or an ac gate voltage using the Floquet master-equation approach. Both types of ac driving lead to…
What is the probability that a large random matrix has no real eigenvalues

We study the large-$n$ limit of the probability $p_{2n,2k}$ that a random $2n\times 2n$ matrix sampled from the real Ginibre ensemble has $2k$ real eigenvalues. We prove that, $$\lim_{n\rightarrow…
Spin amplification, reading, and writing in transport through anisotropic magnetic molecules
Inelastic transport through a single magnetic molecule weakly coupled to metallic leads is studied theoretically. We consider dynamical processes that are relevant for writing, storing, and reading…
