Many-body approach to non-Hermitian physics in fermionic systems
Eunwoo Lee, Hyunjik Lee, Bohm-Jung Yang
In previous studies, the topological invariants of 1D non-Hermitian systems have been defined in open boundary condition (OBC) to satisfy the bulk-boundary correspondence. The extr…

Fractional charge bound to a vortex in two dimensional topological crystalline insulators
Eunwoo Lee, Akira Furusaki, Bohm-Jung Yang
We establish the correspondence between the fractional charge bound to a vortex in a textured lattice and the relevant bulk band topology in two-dimensional (2D) topological crysta…
