## Description

- description: "Optical nonlinearities of bound electrons reveal information about
    both the in-plane rotational and out-of-plane inversion symmetries of a crystal.
    In the van der Waals material hexagonal boron nitride (hBN) both these symmetries
    and the linear vibrational properties have led to the rich physics of mid-infrared
    phonon-polaritons. However, the role of strong electron-phonon nonlinearities
    requires further study. In this work, we investigate both theoretically and experimentally
    the rich interplay of ionic anharmonicity and symmetry in phonon-polariton mediated
    nonlinear optics. We show that large enhancements (>30×) of third-harmonic generation
    occur for incident femtosecond pulses that are resonant with the hBN phonons.
    In addition, we predict and observe transient sub-picosecond duration second-harmonic
    signals during resonant excitation, which in equilibrium is forbidden by symmetry.
    This surprising result indicates that inversion symmetry breaking of the crystal
    can be optically induced and controlled via phonon interactions by both the power
    and polarization of the pump laser.\r\n"
