In recent years, notions drawn from non-Hermitian physics and parity–time (PT) symmetry have attracted considerable attention. In particular, the realization that the interplay between gain and loss can lead to entirely new and unexpected features has initiated an intense research effort to explore...
The non-Hermitian physics analysis implies that the results referred to in ref. 8 requires an alternative interpretation: the optical forces alone are insufficient to produce optical crystallization8,54, and additional forces, such as viscosity, are essential. Fig. 3: Prevalence of complex modes ...
Many novel concepts in \\(\\mathcal {PT}\\)-symmetric wave transport were initially explored and demonstrated in the conceptually simpler and experimentally more accessible framework of active electronic circuits. These include eigenmode analysis and spatio-temporal dynamics of the stored energy in ...
