Differential topology of semimetals
Varghese Mathai, Guo Chuan Thiang
The subtle interplay between local and global charges for topological semimetals exactly parallels that for singular vector fields. Part of this story is the relationship between c…

Global topology of Weyl semimetals and Fermi arcs
Varghese Mathai, Guo Chuan Thiang
We provide a manifestly topological classification scheme for generalised Weyl semimetals, in any spatial dimension and with arbitrary Weyl surfaces which may be non-trivially link…

T-duality simplifies bulk-boundary correspondence: the noncommutative case
Keith C. Hannabuss, Varghese Mathai, Guo Chuan Thiang
We state and prove a general result establishing that T-duality simplifies the bulk-boundary correspondence, in the sense of converting it to a simple geometric restriction map. Th…
