Effective field theory of magnon: Dynamics in chiral magnets and Schwinger mechanism
Masaru Hongo, Toshiaki Fujimori, Tatsuhiro Misumi +2
We develop the effective field theoretical descriptions of spin systems in the presence of symmetry-breaking effects: the magnetic field, single-ion anisotropy, and Dzyaloshinskii-…
Instantons in Chiral Magnets
Masaru Hongo, Toshiaki Fujimori, Tatsuhiro Misumi +2
We exhaustively construct instanton solutions and elucidate their properties in one-dimensional anti-ferromagnetic chiral magnets based on the nonlinear sigma model descript…
Electromagnetic response and pseudo-zero-mode Landau levels of bilayer graphene in a magnetic field
T. Misumi, K. Shizuya
The electromagnetic response of bilayer graphene in a magnetic field is studied in comparison with that of monolayer graphene. Both types of graphene turn out to be qualitatively q…
The zero-energy Landau levels in graphene as BPS-saturated states
Tatsuhiro Misumi
This paper has been withdrawn by the author, due to the crucial mistake of the discussion in Sec IV.
