Gyrotropic magnetic effect in metallic chiral magnets
Nisarga Paul, Takamori Park, Jung Hoon Han +1
We study the gyrotropic magnetic effect (GME), the low-frequency limit of optical gyrotropy, in metals and semimetals coupled to chiral spin textures. In these systems, the chiral…

Quantum geometry from the Moyal product: quantum kinetic equation and non-linear response
Takamori Park, Xiaoyang Huang, Lucile Savary +1
We systematically derive the dissipationless quantum kinetic equation for a multi-band free fermionic system with U(1) symmetry. Using the Moyal product formalism, we fully band-di…

An exact method for bosonizing the Fermi surface in arbitrary dimensions
Takamori Park, Leon Balents
Inspired by the recent work by Delacretaz et. al., we rigorously derive an exact and simple method to bosonize a non-interacting fermionic system with a Fermi surface starting from…
