| Research Abstract |
We have investigated varieties of material consists of triangle units with spin chirality, including spin tube and spin polyhedron. The excitation by the spin chirality sector is found in the spin tube and the change of the ground state from spin singlet to the spin freezing state is found in the spin polyhedron. We have found the role of nuclear spin in quantum tunneling through the parity conservation. A new hetero-spin systems and nuclear spin free quantum magnets are also investigated.
