Influence of the dissipation on the N-level atom interacting with a two two-level atoms in presence of qubit–qubit interaction

Abstract The interacting of two qubits and an N-level atom based on su(2) Lie algebra in the presence of both qubit–qubit interaction and dissipation term is considered. The effects of the qubit–qubit interaction and the dissipation term on the dynamics of the proposed system are discussed in detail...
