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.

D Bermúdez,JFC David - 《Physics Letters A》 被引量: 55发表: 2011年 PT symmetry in optics Interest in complex Hamiltonians has been rekindled after the realization that a wide class of non-Hermitian Hamiltonians can have entirely real spectra as long as they simultaneously respect parity and...
Here we utilize random-matrix theory to show that this spontaneous PT-symmetry breaking can occur via two distinct mechanisms, whose predominance is associated to different universality classes. Present optical experiments fall into the orthogonal class, where symmetry-induced level crossings render the ...
