Abstract
It has recently been shown that the non-Hermitian skin effect can be suppressed by magnetic fields.In this work,using a two-dimensional tight-binding lattice,we demonstrate that a pseudomagnetic field can also lead to the suppression of the non-Hermitian skin effect.With an increasing pseudomagnetic field,the skin modes are found to be pushed into the bulk,accompanied by the reduction of skin topo-logical area and the restoration of Landau level energies.Our results provide a time-reversal invariant route to localization control and could be useful in various classical wave devices that are able to host the non-Hermitian skin effect but inert to magnetic fields.
