Noncollinear magnetic order in quasicrystals
E. Y. Vedmedenko, U. Grimm, R. Wiesendanger
Based on Monte-Carlo simulations, the stable magnetization configurations of an antiferromagnet on a quasiperiodic tiling are derived theoretically. The exchange coupling is assume…

Electron wavepacket propagation and entanglement in a chain of coupled quantum dots
G. M. Nikolopoulos, D. Petrosyan, P. Lambropoulos
We study the coherent dynamics of one- and two-electron transport in a linear array of tunnel-coupled quantum dots. We find that this system exhibits a rich variety of coherent phe…
