Topological Order Parameters of the Spin-1/2 Dimerized Heisenberg Ladder in Magnetic Field
Toshikaze Kariyado, Yasuhiro Hatsugai
Topological properties of the spin-1/2 dimerized Heisenberg ladder are investigated focusing on the plateau phase in the magnetic field whose magnetization is half of the saturatio…

Fractionally Quantized Berry Phase, Adiabatic Continuation, and Edge States
Toshikaze Kariyado, Yasuhiro Hatsugai
Symmetry protected quantization of the Berry phase is discussed in relation to edge states. Assuming an existence of some adiabatic process which protects quantization of the Berry…
