- Abstract:
1. Topological materials: Moebius nanographite and conjugated polymers
2. Magnetic domain wall states [1] vs. helical magmetic order in nanographite [2]
3. Static polarizability α and the first hyperpolarizability β are studied, comparing three models: Mobius strip cyclacene, ring cyclacene, and linear strip.
4. Opening the knot of the Mobius to form the ring leads to the increase of α from 268 to 323 a.u. and β increases about three times from 393 to 1049 a.u.
5. Opening the ring to form the linear strip, α increases from 323 to 476 a.u. β as well increases about three times from 1049 to 2814 a.u.[1] K. Wakabayashi and K. Harigaya, J. Phys. Soc. Jpn. 72, 998 (2003).
