Testing for majorana zero modes in a px+ipy superconductor at high temperature by tunneling spectroscopy
Physical Review Letters 101:26 (2008)
Abstract:
Directly observing a zero energy Majorana state in the vortex core of a chiral superconductor by tunneling spectroscopy requires energy resolution better than the spacing between core states Δ02/ F. We show that, nevertheless, its existence can be decisively tested by comparing the temperature-broadened tunneling conductance of a vortex with that of an antivortex even at temperatures T≫Δ02/ F. © 2008 The American Physical Society.Contact line dynamics in binary lattice Boltzmann simulations

Nonequilibrium transport through a point contact in the nu = 5/2 non-Abelian quantum Hall state.
Physical review letters 101:23 (2008) 236801
Abstract:
We analyze charge-e/4 quasiparticle tunneling between the edges of a point contact in a non-Abelian model of the nu = 5/2 quantum Hall state in the presence of a finite voltage difference using the time-dependent density-matrix renormalization group method. We confirm that, as the voltage decreases, the system is broken into two pieces. In the limits of small and large voltage, we recover the results expected from perturbation theory about the infrared and ultraviolet fixed points. We test our methods by finding the analogous nonequilibrium current through a point contact at nu = 1/3.Topological order from quantum loops and nets
