Abstract:
Driven systems are of great importance in physics. Most systems realisable
experimentally are non-equilibrium system and involves some sort of currents
or dissipation. But, these systeM.S. are very hard to treat theoretically. It is
hard to treat systeM.S. considerably far from equilibrium with the techniques
derived for equilibrium systeM.S.. Floquet systeM.S. act as a bridge in this
sense. These systeM.S. can be described by an e ective time independent
Hamiltonian, the Floquet Hamiltonian. We saw some methods of calculating
the same in Chapter 1.
