RESEARCH

We are researching the phenomenon that the electron group in such a situation causes in the crystal where the effective magnetic field differs depending on the movement direction and the space inversion symmetry is broken.

We are studying the electric field response phenomena of electric field in the system where we synthesize type II Weyl semimetal single crystal containing magnetic element and broken not only space inversion symmetry but also time inversion symmetry.
