Theory of terahertz pump optical probe spectroscopy of phonon polaritons in noncentrosymmetric systems
Abstract Hybrid lattice-light modes, known as phonon polaritons, represent the backbone of advanced protocols based on THz pumping of infrared modes. Here we provide a theoretical framework able to capture the different roles played by phonon polaritons in experimental protocols based either on Rama...
