We construct an instanton describing the pair production of non-Kaluza Klein bubbles of nothing in higher odd dimensional de Sitter spaces. In addition to showing that higher dimensional de Sitter spa...
Analysis of instabilities and pattern formation in time fractional reaction-diffusion systems
instabilities pattern formation time fractional reaction-diffusion systems

We analyzed conditions for Hopf and Turing instabilities to occur in two-component fractional reaction-diffusion systems. We showed that the eigenvalue spectrum and fractional derivative order mainly ...
Surface-Wave Instabilities in a Plasma Rotating with Step-like Frequency Profile
Magnetorotational instability Plasma rotational instability
2010/7/5
An approach for the theory of nonlocal magnetorotational and convective instabilities in a rotating plasma is developed, on the basis of the surface wave concept, which allows the derivation of useful...
Behavior of Linear Beam-Plasma Instabilities in the Presence of Finite Amplitude Circularly Polarized Waves
Linear Beam-Plasma Instabilities Finite Amplitude Circularly Polarized Waves
2010/10/27
We review the effect of finite amplitude circularly polarized waves on the behavior of linear ion-beam plasma instabilities. It has been shown that left-hand polarized waves can stabilize linear right...
