Abstract
We study the effect of circularly polarized electromagnetic radiation on optical polarons in monolayer \b{eta}-borophene. We focus on the off-resonant regime of large driving frequencies, which allows to set up an effectively time-independent Hamiltonian describing the radiation field in up to second perturbational order. The contributions of optical surface phonons are incorporated according to Lee-Low-Pines theory, via a sequence of appropriate unitary transformations. A central object in our investigation is the electronic band gap, which is shown to be widely controllable via the variation of light irradiation and substrate properties.
