Blowup of Multi-Peaked Waveforms in the Two-Dimensional Nonlinear Schroedinger Model
S. Jon Chapman, M. Kavousanakis, E. G. Charalampidis +2
In the present work, we explore the self-focusing and resulting collapse of two-dimensional waveforms involving multiple pulses in a nonlinear Schroedinger equation with a general…

The continuous spectrum of bound states in expulsive potentials
H. Sakaguchi, B. A. Malomed, A. C. Aristotelous +1
On the contrary to the common intuition, which suggests that a steep expulsive potential makes quantum states widely delocalized, we demonstrate that one- and two-dimensional (1D a…

Stability and mixed phases of three-component droplets in one dimension
I. A. Englezos, E. G. Charalampidis, P. Schmelcher +1
We explore the ground state properties and excitation spectra of one-dimensional three-component bosonic mixtures accommodating a droplet in two of the species and a third minority…
