A non-commutative Reidemeister-Turaev torsion of homology cylinders
Yuta Nozaki, Masatoshi Sato, Masaaki Suzuki
We compute the Reidemeister-Turaev torsion of homology cylinders which takes values in the -group of the -adic completion of the group ring , and prov…
Non-Hermitian topological phenomena: A review
Nobuyuki Okuma, Masatoshi Sato
The past decades have witnessed an explosion of interest in topological materials, and a lot of mathematical concepts have been introduced in condensed matter physics. Among them,…
Bulk-boundary correspondence in point-gap topological phases
Daichi Nakamura, Takumi Bessho, Masatoshi Sato
A striking feature of non-Hermitian systems is the presence of two different types of topology. One generalizes Hermitian topological phases, and the other is intrinsic to non-Herm…
Correspondence of topological classification between quantum graph extra dimension and topological matter
Tomonori Inoue, Makoto Sakamoto, Masatoshi Sato +1
In this paper, we study five-dimensional Dirac fermions of which extra-dimension is compactified on quantum graphs. We find that there is a non-trivial correspondence between matri…
