Effect of intersubsystem couplings on the evolution of composite systems
Effect of intersubsystem couplings on the evolution of composite systems
The effect of inter-subsystem coupling on the adiabaticity of composite systems and that of its subsystems is investigated. Similar to the adiabatic evolution defined for pure states, non-transitional evolution for mixed states is introduced; conditions for the non-transitional evolution are derived and discussed. An example that describes two coupled qubits …
