Non-Hermitian Topological Anderson Insulators
Dan-Wei Zhang, Ling-Zhi Tang, Li-Jun Lang +2
Non-Hermitian systems can exhibit unique topological and localization properties. Here we elucidate the non-Hermitian effects on disordered topological systems by studying a non-He…
On the number of intersection points of the contour of an amoeba with a line
Lionel Lang, Boris Shapiro, Eugenii Shustin
In this note, we investigate the maximal number of intersection points of a line with the contour of hypersurface amoebas in . We define the latter number to be the $…
Monodromy of rational curves on toric surfaces
Lionel Lang
For an ample line bundle on a complete toric surface , we consider the subset of irreducible, nodal, rational cur…
Interplay of non-Hermitian skin effects and Anderson localization in non-reciprocal quasiperiodic lattices
Hui Jiang, Li-Jun Lang, Chao Yang +2
Non-Hermiticity from non-reciprocal hoppings has been shown recently to demonstrate the non-Hermitian skin effect (NHSE) under open boundary conditions (OBCs). Here we study the in…
