Exotic quantum phenomena of the spin nanotubes

Sakai, Toru; Okamoto, Kiyomi*

The spin nanotubes are theoretically investigated by the numerical diagonalization and the density matrix renormalization group calculation. As a result, it is found that a quantum phase transition from the spin gapped to the gapless phases is induced by the lattice distortion. We also discuss about a possible superconductivity induced by the chirality degrees of freedom.
