Effective and Efficient Resonant Transitions in Periodically Modulated Quantum Systems
Quantum Reports, 2021 We analyze periodically modulated quantum systems with SU(2) and SU(1,1) symmetries. Transforming the Hamiltonian into the Floquet representation we apply the Lie transformation method, which allows us to classify all effective resonant transitions ...
