Pseudomagnetic suppression of non-Hermitian skin effect

Caption

By implementing pseudomagnetic field (PMF) in the array with non-Hermitian skin effect (NHSE), the team from Singapore and Hong Kong discovered that the skin states can be suppressed into the bulk. The skin topological area is also suppressed, followed by recovery of flat energy levels (Landau levels).
