Schematic of non-Hermitian reshaping of Landau modes.

Caption

This schematic illustrates how to reshape high-order Landau modes. By constructing artificial gauge fields and imaginary momentum, the inherently diffuse and multi-peak wave packets are successfully separated by energy and reshaped into different patterns on demand.
