## Description

- description: "Floquet engineering is a promising tool to manipulate quantum systems
    coherently. A well- known example is the optical Stark effect, which has been
    used for optical trapping of atoms and breaking time-reversal symmetry in solids.
    However, as a coherent nonlinear optical effect, Floquet engineering typically
    requires high field intensities obtained in ultrafast pulses, severely limiting
    its use. Here, we show that cavity engineering of the vacuum modes can lead to
    orders-of-magnitude enhancement of the effective Floquet field. We demonstrate
    Floquet effects at an extremely low fluence of 450 photons/μm2 and, at higher
    fluences, up to 50 meV spin and valley splitting of WSe2 excitons, corresponding
    to an enormous time-reversal breaking, non-Maxwellian magnetic field of over 200
    T. Utilizing such an optically-controlled magnetic field, we demonstrate an ul-
    trafast, picojoule chirality XOR gate. These results suggest that cavity Floquet
    engineering may enable the creation of steady-state or quasi-equilibrium Floquet
    bands, strongly non-perturbative modifications of materials beyond the reach of
    other means, and application of Floquet engineering to a wide range of materials
    and applications.\r\n"
