چکیده
We present a consistent way of coupling three-dimensional Maxwell-Chern-Simons gravity theory with massless spin-$\frac{5}{2}$ gauge fields. first introduce the simplest hyper-Maxwell-Chern-Simons generically containing two spin-2 fields coupled Majorana fermion spin $\frac{5}{2}$ whose novel underlying superalgebra is explicitly constructed. then three alternative hypersymmetric extensions Maxwell algebra which are shown to emerge from In\"on\"u-Wigner contraction procedure precise combinations $\mathfrak{o}\mathfrak{s}\mathfrak{p}(1|4)$ and $\mathfrak{s}\mathfrak{p}(4)$ algebras. This allows us construct distinct types theories that extend include interacting nonpropagating spin-4 accompanied by one or

Self-dual Maxwell Chern-Simons Solitons In 1+1 Dimensions
We study the domain wall soliton solutions in the relativistic self-dual Maxwell Chern-Simons model in 1+1 dimensions obtained by the dimensional reduction of the 2 + 1 model. Both topological and nontopological self-dual solutions are found in this case. A la BPS dyons here the Bogomol’ny bound on the energy is expressed in terms of two conserved quantities. We discuss the underlying supersymm...
متن کاملMaxwell-Chern-Simons Casimir effect.
In odd-dimensional spaces, gauge invariance permits a Chern-Simons mass term for the gauge fields in addition to the usual Maxwell-Yang-Mills kinetic energy term. We study the Casimir effect in such a (2+1)-dimensional Abelian theory. For the case of parallel conducting lines the result is the same as for a scalar field. For the case of circular boundary conditions the results are completely di...
متن کاملQ-balls in Maxwell-Chern-Simons theory
We examine the energetics of Q-balls in Maxwell-Chern-Simons theory in two space dimensions. Whereas gauged Q-balls are unallowed in this dimension in the absence of a Chern-Simons term due to a divergent electromagnetic energy, the addition of a Chern-Simons term introduces a gauge field mass and renders finite the otherwise-divergent electromagnetic energy of the Q-ball. Similar to the case o...
