We present a self-dual parity-invariant Maxwell-Chern-Simons scalar . We show that the energy functional admits a Bogomol'nyi-type lower bound, whose saturation gives rise to first order self-duality equations. We perform a detailed analysis of this system, discussing its main features and exhibiting explicit numerical solutions corresponding to finite-energy topological vortices and non-topological solitons. The mixed Chern-Simons term plays an important role here, ensuring the main properties of the model and suggesting possible applications in condensed matter.

奇偶不变场景中的自对偶 Maxwell-Chern-Simons 孤子
我们提出了一个自对偶奇偶不变量Maxwell-Chern-Simons 标量. 我们证明能量泛函具有 Bogomol'nyi 型下界,其饱和度产生一阶自对偶方程。我们对该系统进行了详细的分析,讨论了它的主要特征,并展示了与有限能量拓扑涡旋和非拓扑孤子相对应的显式数值解。混合 Chern-Simons 项在这里起着重要作用,确保模型的主要特性并建议在凝聚态物质中的可能应用。
