Adiabatic passage in the presence of noise

Now add to this Hamiltonian a term that couples the two states, yielding a new Hamiltonian H � . The eigenstates of H � will exhibit an avoided crossing as a function of ω. Consider suchacoupledsysteminitiallyinaneigenstateof H with ω set such that the energy splitting between the states is much larger than the coupling energy. If ω is now varied sufficiently slowly across the energy level crossing, the system will adiabatically
