Chaotic solitons in driven sine-Gordon model
D. G. Levkov, V. E. Maslov, E. Ya. Nugaev
Profiles of static solitons in one-dimensional scalar field theory satisfy the same equations as trajectories of a fictitious particle in multidimensional mechanics. We argue that…

Review of non-topological solitons in theories with -symmetry
Emin Nugaev, Andrey Shkerin
We provide a review of non-topological solitonic solutions arising in theories with a complex scalar field and global or gauge -symmetry. It covers Q-balls, homogeneous charg…

Vibrational modes of Q-balls
A. Kovtun, E. Nugaev, A. Shkerin
We study linear perturbations of classically stable Q-balls in theories admitting analytic solutions. Although the corresponding boundary value problem is non-Hermitian, the analys…
