Band Tuning of a Phosphorene Semiconductor via Floquet Theory

Graphene and phosphorene comprise a monolayer of graphite and phosphorous, respectively. The Floquet theory is an alternative way to study Rabi oscillations in the off-resonance case and dominates in the case of low-energy physics. In this article, the nature of collapse-revival and Bloch–Siegert shift phenomena have been studied under an intense applied quantized electromagnetic field for graphene and phosphorene. It was found that anisotropy is a crucial property of phosphorene and has a significant role in low-energy physics. A numerical model is also applied to justify the role of anisotropy for phosphorene. Floquet frequency can be also utilized for band tuning of this type of fermionic systems.
