High winding number of topological phase in periodic quantum walks

open access: closedPhysics Letters A, 2021
Abstract We construct one-dimensional multi-period quantum walks to investigate the topological phases with high winding number. It is found that the maximum of winding number is determined by the number of shift operation in one-step evolution only under an appropriate time frame.

Quantum numbers and band topology of nanotubes

Journal of Physics A: Mathematical and General, 2003
Summary: Nanotubes as well as polymers and quasi-1D subsystems of 3D crystals have line group symmetry. This allows two types of quantum numbers: roto-translational and helical. The roto-translational quantum numbers are linear and total angular (not conserved) momenta, while the helical quantum numbers are helical and complementary angular momenta ...
