Coherent control of the two-dimensional spatial distribution of probe absorption in a graphene-based quantum system

We investigate two-dimensional (2D) position-dependent probe absorption in monolayer graphene. Specifically, we consider quantized three-level graphene driven by an infrared probe field, two orthogonal terahertz standing-wave fields, and a coupling field. Our results demonstrate that the spatial distribution of probe absorption can be effectively controlled by adjusting the detunings of the probe and standing-wave fields, as well as the Rabi frequency of the coupling field. The absorption spectrum of the probe field exhibits some interesting features, such as crater-like structures and spikes. Our findings provide new insights into the manipulation of optical properties in graphene and have potential applications in solid-state quantum information.
