Striped nanowires and nanorods from mixed SAMS.
We investigate the use of mixed self-assembled monolayers (SAMs) for creating nanoscale striped patterns on nanowires and nanorods. Our simulations predict that SAMs comprised of an equal composition of length-mismatched, thermodynamically incompatible surfactants adsorbed on nanowire surfaces self-organize into equilibrium stripes of alternating composition always perpendicular, rather than pa...
متن کاملEdge and Bulk Transport in the Mixed State of a Type-II Superconductor
By comparing the voltage-current (V − I) curves obtained before and after cutting a sample of 2HNbSe2, we separate the bulk and edge contributions to the transport current at various dissipation levels and derive their respective V − I curves and critical currents. We find that the edge contribution is thermally activated across a current dependent surface barrier. By contrast the bulk V − I cu...
متن کاملMixed state of a dirty two-band superconductor: application to MgB2.
We investigate the vortex state in a two-band superconductor with strong intraband and weak interband electronic scattering rates. Coupled Usadel equations are solved numerically, and the distributions of the pair potentials and local densities of states are calculated for two bands at different values of magnetic fields. The existence of two distinct length scales corresponding to different ba...

متن کاملStriped spin liquid crystal ground state instability of kagome antiferromagnets.
The Dirac spin liquid ground state of the spin 1/2 Heisenberg kagome antiferromagnet has potential instabilities. This has been suggested as the reason why it does not emerge as the ground state in large-scale numerical calculations. However, previous attempts to observe these instabilities have failed. We report on the discovery of a projected BCS state with lower energy than the projected Dir...
