We discuss a simple model for creation of entanglement in a system composed of two two-level atoms interacting with a common environment. The role of the environment in entangling and disentangling of the atoms is explored. We demonstrate how the ...

We study entanglement dynamics of qubit---qutrit pair under Dzyaloshinskii---Moriya (DM) interaction. The qubit---qutrit pair acts as a closed system and one external qubit serve as the environment for the pair. The external qubit interact with qubit of ...

In this paper, we derive unitary Yang-Baxter $${\breve{R}(\theta, \varphi)}$$ matrices from the $${8\times8\,\mathbb{M}}$$ matrix and the 4 4 M matrix by Yang-Baxteration approach, where $${\mathbb{M}/M}$$ is the image of the braid group representation. In Yang-Baxter systems, we explore the evolution of tripartite negativity ...
