Synchronized excitation of magnetization dynamics via spin waves in Bi-YIG thin film by slot line waveguide
Tetsunori Koda, Sho Muroga, Yasushi Endo
We have studied magnetization dynamics of a single Bi-YIG thin film by means of the high frequency power response induced by a slot line waveguide. Multiple absorption peaks that c…
Lattice gauge theory for Haldane conjecture and central-branch Wilson fermion
Tatsuhiro Misumi, Yuya Tanizaki
We develop the d lattice gauge theory in order to define -flavor massless Schwinger model, and discuss its connection with Haldane conjecture. We propose to use th…
Simple proof of Parikh's theorem a la Takahashi
Ryoma Sin'ya
In this report we describe a simple proof of Parikh's theorem a la Takahashi, based on a decomposition of derivation trees. The idea of decomposition is appeared in her master's th…
Confinement-Deconfinement Crossover in the Lattice Model
Toshiaki Fujimori, Etsuko Itou, Tatsuhiro Misumi +2
The sigma model at finite temperature is studied using lattice Monte Carlo simulations on with radii and , respectively,…
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…
A higher speed type II blowup for the five dimensional energy critical heat equation
Junichi Harada
This paper is concerned with blow-up solutions of the five dimensional energy critical heat equation . A goal of this paper is to show the existence of typ…
