Abstract: We investigate the existence, stability and internal interaction of two-dimensional multipole solitons in defocusing PT symmetric nonlocal nonlinear media. Compared with nonlocal fundamental solitons in PT-symmetric lattices, the multipole solitons reveal the novel internal interaction… read more here.

Abstract: Using a Lyapunov type functional constructed on the basis of thermodynamical arguments, we investigate the finite amplitude stability of internal steady flows of viscoelastic fluids described by the Giesekus model. Using the functional, we derive… read more here.
