Fractional Spin Liquid Hierarchy for Spin S

The construction as well as the TD suggests that (10) exhibits (Ising-type) non-Abelian spinon statistics for both chiralities. The S = 2 chirality liquid s ...

Destructive quantum interference in spin tunneling problems
... In this Letter we point out that when there are several different symmetry-related tunneling paths connecting the same degenerate classical ground states, the topological phase can lead to destructive quantum interference between their amplitudes, and hence to a total tunneling amplitude that is exa ...

Immortality: myth or becoming reality?
