Faster-Than-Light Solitons in 1 + 1 Dimensions
Mohammad Mohammadi, Nematollah Riazi, Mohammad Hassan Dhegihani
The existence of a faster-than-light particle is in direct opposition to Einstein's relativity and the principle of causality. However, we show that the theory of classical relativ…
Relativistic k-fields with Massless Soliton Solutions in 3+1 Dimensions
M. Mohammadi, R. Gheisari
In this work, the relativistic non-standard Lagrangian densities (k-fields) with massless solutions are generally introduced. Such solutions are not necessarily energetically stabl…
The Affective Factors on the Uncertainty in the Collisions of the Soliton Solutions of the Double Field sine-Gordon System
Mohammad Mohammadi, Nematollah Riazi
Inspired by the well known sine-Gordon equation, we present a symmetric coupled system of two real scalar fields in dimensions. There are three different topological soliton…
Stability Catalyzer for a Relativistic Non-Topological Soliton Solution
Mohammad Mohammadi
For a real nonlinear Klein-Gordon Lagrangian density with a special solitary wave solution (SSWS), which is essentially unstable, it is shown how adding a proper additional massles…
The Super Lie Groups Associated to Odd Involutions
Mohammad Mohammadi, Saad Varsaie
A new generalization of Grassmannians in supergeometry, called Grassmannians, are constructed by gluing domains. By a domain, we mean a superdomain with an odd involuti…
On the Construction of Supergrassmannians as Homogeneous Superspaces
Mohammad Mohammadi, Saad Varsaie
In this paper, we construct the supergrassmannians by gluing of the superdomains and give an explicit description of the action of the $\mat…
Zero Rest Mass Soliton Solutions
Mohammad. Mohammadi, Rohollah. Gheisari
In this paper, extended Klein-Gordon field systems will be introduced. Theoretically, it will be shown that for a special example of these systems, it is possible to have a single…
