We demonstrate that an aperiodic array of certain quantum networks comprising magnetic and nonmagnetic atoms can act as perfect spin filters for particles with arbitrary spin state …

This review is an explorer's walk that revisits the character of single particle states and charge transport in a class of low dimensional decorated lattices. The systems considered …
We investigate a simple tight-binding Hamiltonian to understand the stability of spin- polarized transport of states with an arbitrary spin content in the presence of disorder. The …
We show that a quasiperiodic magnetic chain comprising magnetic atomic sites sequenced in a Fibonacci pattern can act as a prospective candidate for spin filters for particles with …
Y Zhang - International Journal of Modern Physics B, 2018 - World Scientific
Spin transport properties of a double-triangular quantum network with local magnetic moment on backbones and magnetic flux penetrating the network plane are studied …
The interplay between strong interactions and disorder is at the core of one of the most exciting and active fields of modern quantum condensed matter physics. In the last two …
