The energy-frequency diagram of the (1+1)-dimensional oscillon
N. V. Alexeeva, I. V. Barashenkov, Alain Dika +1
Two different methods are used to study the existence and stability of the (1+1)-dimensional oscillon. The variational technique approximates it by a periodic function with a…
Variational formalism for the Klein-Gordon oscillon
I. V. Barashenkov, N. V. Alexeeva
The variational method employing the amplitude and width as collective coordinates of the Klein-Gordon oscillon leads to a dynamical system with unstable periodic orbits that blow…
Understanding oscillons: standing waves in a ball
N. V. Alexeeva, I. V. Barashenkov, A. A. Bogolubskaya +1
Oscillons are localised long-lived pulsating states in the three-dimensional theory. We gain insight into the spatio-temporal structure and bifurcation of the oscillons by st…
