Scaling of pseudospectra in exponentially sensitive lattices

One of the important features of non-Hermitian Hamiltonians is the existence of a unique type of singularities, the so-called exceptional points. When the corresponding systems operate around such singularities, they exhibit ultrasensitive behavior that has no analog in conservative systems. An alte...
