Berry's phase in the Floquet representation

Research output: Contribution to journalArticlepeer-review

3 Scopus citations


By means of the Floquet theory the investigation of Berry's phase for the quantum system with time-dependent periodic Hamiltonian is transformed into the study of a time-independent eigenvalue equation. An expression for the infinite-dimensional matrix is obtained describing the Berry's phase in terms of the Floquet state.
