Magnetic field induced topological semimetals near a quantum critical point of pyrochlore iridates
Taekoo Oh, Hiroaki Ishizuka, Bohm-Jung Yang
Motivated by the recent experimental observation of anomalous magneto-transport properties near the Mott quantum critical point (QCP) of pyrochlore iridates, we study the generic t…
Noncommutative quantum mechanics and skew scattering in ferromagnetic metals
Hiroaki Ishizuka, Naoto Nagaosa
The anomalous Hall effect in ferromagnetic metals is classified into two based on the mechanism. The first one is the intrinsic Hall effect due to the Berry curvature in momentum s…
Local photo-excitation of shift current in noncentrosymmetric systems
Hiroaki Ishizuka, Naoto Nagaosa
Photocurrent in solids is an important phenomenon with many applications including the solar cells. In conventional photoconductors, the electrons and holes created by light irradi…
Momentum-Space Electromagnetic Induction in Weyl Semimetals
Hiroaki Ishizuka, Tomoya Hayata, Masahito Ueda +1
We theoretically study the effect of the Berry curvature on the transport properties of Weyl semimetals in the nonadiabatic process, which results in nonlinear optical responses. I…
