Signature of structural parameter in Floquet spectra of a - T-3 lattice model

Abstract

The impact of structural parameter is described in the Floquet spectra of α−T3 lattice model. There is a comparison between classical and quantum Floquet frequency by using the Jaynes–Cummings model. The collapse–revival behaviour of Floquet oscillations has been studied and found that structural parameter has a major impact on collapse–revival time. The pump–probe experiment has been studied theoretically for the detection of Floquet oscillation. The study of Rabi oscillation has been performed. There is a modification in the Rabi frequency after including counter-rotating term i.e. Bloch–Siegert shift. The Bloch–Siegert shift has been studied in the perspective of structural parameter. The band tuning is described with help of Floquet frequency. To justify analytical expression of Floquet frequency, a numerical simulation has been performed.
