Entropic crystallization of geometrically frustrated magnets on 1/1 approximant Tsai-type quasicrystal
Oscar Novat, Ludovic D. C. Jaubert, Masafumi Udagawa
We have studied the antiferromagnetic Ising model on the icosahedral bcc lattice, as a model system of 1/1 approximant Tsai-type quasicrystals. We addressed thermal equilibrium pro…
Strong deflection of massive particles via the geodesic deviation equation
Takahisa Igata, Yohsuke Takamori
We develop a formulation of the strong deflection limit for the scattering of particles following timelike geodesics in asymptotically flat, static, and spherically symmetric space…
Strong-deflection expansion of the deflection angle near a degenerate photon sphere
Takahisa Igata, Tadashi Sasaki, Naoki Tsukamoto
We present a strong-deflection expansion for the deflection angle of light rays scattered near a degenerate photon sphere in asymptotically flat, static, and spherically symmetric…
PyAPX: Python toolkit for atomic configuration pattern exploration
Akira Kusaba, Tetsuji Kuboyama, Karol Kawka +2
In materials discovery, the integration of first-principles calculations with machine learning techniques has been actively studied for two key tasks: crystal structure prediction,…
Spinon band flattening by its emergent gauge field in quantum kagome ice
Masafumi Udagawa, Roderich Moessner
Fractional excitations provide a key to identifying sought-after topological quantum spin liquid states in realistic materials. Their single-particle dynamics already presents a ch…
Superconductivity and Low Energy Excitations in an Attractive Hubbard Model
Yukimi Goto, Tohru Koma, Hironobu Yoshida
We study an attractive Hubbard model on bipartite lattices. In the grand canonical formalism,we prove the existence of superconducting long-range order in the ground state on Lieb…
