Emergent Mott insulators and non-Hermitian conservation laws in an interacting bosonic chain with noninteger filling and nonreciprocal hopping
Zuo Wang, Li-Jun Lang, Liang He
We investigate the ground state and quantum dynamics of an interacting bosonic chain with the nonreciprocal hopping. In sharp contrast to its Hermitian counterpart, the ground stat…

Non-Hermitian topological end breathers
Li-Jun Lang, Shi-Liang Zhu, Y. D. Chong
Nonlinearities in lattices with topologically nontrivial band structures can give rise to topological solitons, whose properties differ from both conventional lattice solitons and…

Patchworking the Log-critical locus of planar curves
Lionel Lang, Arthur Renaudineau
We establish a patchworking theorem à la Viro for the Log-critical locus of algebraic curves in . As an application, we prove the existence of projective curves o…
