Description:
Author(s): Stefano Longhi We investigate the onset of parity-time ( PT ) symmetry breaking in non-Hermitian tight-binding lattices with spatially-extended loss-gain regions in the presence of an advective term. Similarly to the instability properties of hydrodynamic open flows, it is shown that PT symmetry breaking can be eith... [Phys. Rev. A 88, 052102] Published Wed Nov 06, 2013
