Semiclassical Theory of Integrable and Rough Andreev Billiards
W. Ihra, M. Leadbeater, J. L. Vega +1
We study the effect on the density of states in mesoscopic ballistic billiards to which a superconducting lead is attached. The expression for the density of states is derived in t…

Direct exchange in the edge-sharing spin-1/2 compound MgVO_3
I. Chaplygin, R. Hayn, K. Koepernik
Bandstructure calculations with different spin arrangement for the spin-chain compound MgVO_3 have been performed, and paramagnetic as well as magnetic solutions with ferro- and an…
