Plasmonic quantum nonlinear Hall effect in noncentrosymmetric 2D materials
Riki Toshio, Norio Kawakami
We investigate an interplay between quantum geometrical effects and surface plasmons through surface plasmonic structures, based on an electron hydrodynamic theory. First we demons…
Vorticity-induced anomalous Hall effect in electron fluid
Hiroshi Funaki, Riki Toshio, Gen Tatara
We develop a hydrodynamic theory for an electron system exhibiting the anomalous Hall effect, and show that an additional anomalous Hall effect is induced by a vorticity generated…
Anomalous Hydrodynamic Transport in Interacting Noncentrosymmetric Metals
Riki Toshio, Kazuaki Takasan, Norio Kawakami
In highly conductive metals with sufficiently strong momentum-conserving scattering, the electron momentum is regarded as a long-lived quantity, whose dynamics is described by an e…
Nonlocal optical responses of ultrapure metals in the hydrodynamic regime
Riki Toshio, Kazuaki Takasan, Norio Kawakami
Our conventional understanding of optical responses in metals has been based on the Drude theory. In recent years, however, it has become possible to prepare ultrapure metallic sam…
