Exponential growth of ponds in invasion percolation on regular trees
Jesse Goodman
In invasion percolation, the edges of successively maximal weight (the outlets) divide the invasion cluster into a chain of ponds separated by outlets. On the regular tree, the pon…
Theory of non-Abelian Fabry-Perot interferometry in topological insulators
Johan Nilsson, A. R. Akhmerov
Interferometry of non-Abelian edge excitations is a useful tool in topological quantum computing. In this paper we present a theory of a non-Abelian edge state interferometer in a…
Domain wall in a chiral p-wave superconductor: a pathway for electrical current
I. Serban, B. Beri, A. R. Akhmerov +1
Superconductors with p+ip pairing symmetry are characterized by chiral edge states, but these are difficult to detect in equilibrium since the resulting magnetic field is screened…
The SAURON project - XV. Modes of star formation in early-type galaxies and the evolution of the red sequence
K. L. Shapiro, J. Falcon-Barroso, G. van de Ven +15
We combine SAURON integral field data of a representative sample of local early-type, red sequence galaxies with Spitzer/IRAC imaging in order to investigate the presence of trace…
Conducting-angle-based percolation in the XY model
Yancheng Wang, Wenan Guo, Bernard Nienhuis +1
We define a percolation problem on the basis of spin configurations of the two dimensional XY model. Neighboring spins belong to the same percolation cluster if their orientations…
Force balance in canonical ensembles of static granular packings
Brian P. Tighe, Thijs J. H. Vlugt
We investigate the role of local force balance in the transition from a microcanonical ensemble of static granular packings, characterized by an invariant stress, to a canonical en…
