Complex periodic potentials with real band spectra [PDF]
, 1998 This paper demonstrates that complex PT-symmetric periodic potentials possess real band spectra. However, there are significant qualitative differences in the band structure for these potentials when compared with conventional real periodic potentials ...

Instantaneous modulations in time-varying complex optical potentials [PDF]
New Journal of Physics, 2017 We study the impact of a spatially homogeneous yet non-stationary dielectric permittivity on the dynamical and spectral properties of light. Our choice of potential is motivated by the interest in ${ \mathcal P }{ \mathcal T }$ -symmetric systems as an ...

Isoresonant complex-valued potentials and symmetries [PDF]
Canadian Journal of Mathematics, 2009 Let $X$ be a connected Riemannian manifold such that the resolvent of the free Laplacian $(\Delta-z)^{-1}, z\in\C\setminus\R^{+},$ has a meromorphic continuation through $\R^{+}$. The poles of this continuation are called resonances.

Attack Potential in Impact and Complexity [PDF]
Proceedings of the 12th International Conference on Availability, Reliability and Security, 2017 Vulnerability exploitation is reportedly one of the main attack vectors against computer systems. Yet, most vulnerabilities remain unexploited by attackers. It is therefore of central importance to identify vulnerabilities that carry a high `potential for attack'. In this paper we rely on Symantec data on real attacks detected in the wild to identify a

Electrical Potentials in Stomatal Complexes [PDF]
Plant Physiology, 1981 Guard cells of several species, but predominantly Commelina communis, were impaled by micropipette electrodes and potential differences measured that occurred between cell compartments and the flowing bathing medium. The wall developed a Donnan potential that was between -60 and -70 millivolt in 30 millimolar KCl at pH 7.

Dissociation of quarkonium in a complex potential [PDF]
Physical Review D, 2014 We have studied the quasi-free dissociation of quarkonia through a complex potential which is obtained by correcting both the perturbative and nonperturbative terms of the $Q \bar Q$ potential at T=0 through the dielectric function in real-time formalism.
