Chiral orbital texture in nonlinear electrical conduction
Suguru Okumura, Ryutaro Tanaka, Daichi Hirobe
Nonlinear electrical conduction primarily mediated by an orbital texture is observed in chiral semiconductor Te. We determine the enantiospecific sign of the nonlinear conductance…

Spectral analysis of Dirac operators for fermion scattering on topological solitons in the nonlinear -model
Daiju Funakawa, Satoshi Okumura, Yuki Ueda
We investigate the existence of discrete positive or negative energy ground states of the Dirac operator which describe the fermion scattering on topological solitons in the no…
