Perturbation Theory for PT-Symmetric Sinusoidal Optical Lattices at the Symmetry-Breaking Threshold
PT-Symmetric Sinusoidal Optical the Symmetry-Breaking Threshold
2011/8/31
The PT symmetric potential V0[cos(2x/a)+i sin(2x/a)] has a completely real spectrum for ≤ 1, and begins to develop complex eigenvalues for > 1. At the
symmetry-breaking threshold = 1 some of...
Use of Equivalent Hermitian Hamiltonian for $PT$-Symmetric Sinusoidal Optical Lattices
Equivalent Hermitian Hamiltonian $PT$-Symmetric Sinusoidal Optical Lattices
2010/10/27
show how the band structure and beam dynamics of non-Hermitian PT-symmetric sinusoidal optical lattices can be approached from the point of view of the equivalent Hermitian problem, obtained by an ana...
