7-branes and Duality in Type 0B String Theory
Naoto Kan, Masashi Kawahira, Hiroki Wada
We investigate 7-branes in type 0B string theory, motivated by the recent proposal of Baykara, Dudas, and Vafa, which connects type 0B string theory with M-theory. On the -symme…

Time-reversal invariant vortex in topological superconductors and gravitational topology
Kazuki Yamamoto, Naoto Kan, Hidenori Fukaya
We study a time-reversal invariant vortex, namely a spin vortex, in helical superconductors by focusing on its emergent gravitational structure. The topology of the time-reversal i…

Lattice Weyl Fermion on a Single Spherical Domain-Wall
Shoto Aoki, Hidenori Fukaya, Naoto Kan
We investigate a single spherical domain-wall embedded in a three-dimensional Euclidean lattice. We employ the Shamir-type domain-wall fermion formulation, where the negative mass…
