A quantum system with time-dependent H has two energy states: E1​(t)=Δ+b∣t∣,E2​=−b∣t∣,Δ,b>0 In the adiabatic regime, of the system has energy 0 at time t=0, what will be the energy at time t>0 ? What is the probability of a diabatic transition oceuring from the second into the first state between t→−[infinity] and t→[infinity]?
