Quantum implementation of non-unitary operations with biorthogonal representations
Efstratios Koukoutsis, Panagiotis Papagiannis, Kyriakos Hizanidis +5
Motivated by the contemporary advances in quantum implementation of non-unitary operations, we propose a new dilation method based on the biorthogonal representation of the non-uni…
Scattering of radio frequency waves by cylindrical blobs in the plasma edge in tokamaks
S. I. Valvis, K. Hizanidis, P. Papagiannis +5
Radio frequency waves are routinely used in tokamak fusion plasmas for plasma heating, current control, and as well as in diagnostics. These waves are excited by antenna structures…
Power and momentum dependent soliton dynamics in lattices with longitudinal modulation
Panagiotis Papagiannis, Yannis Kominis, Kyriakos Hizanidis
Soliton dynamics in a large variety of longitudinally modulated lattices are studied in terms of phase space analysis for an effective particle approach and direct numerical simula…
Spatiotemporal interaction of optical beams in bi-dispersive media
Nikolaos Moshonas, Yannis Kominis, Panagiotis Papagiannis +2
The interaction of optical beams in bi-dispersive nonlinear media with self-focusing nonlinearity is numerically investigated. Under proper conditions, the interaction of spatially…
Three-dimensional vortex solitons in self-defocusing media
Nikolaos K. Efremidis, Kyriakos Hizanidis, Boris A. Malomed +1
We demonstrate that families of vortex solitons are possible in a bi-dispersive three-dimensional nonlinear Schrodinger equation. These solutions can be considered as extensions of…
