The advent of terahertz (THz) cavities offers new possibilities for the dynamical control and manipulation of correlated materials. In contrast to Floquet engineering and optical switching approaches, these enable the modification of vacuum fluctuations and thereby to enhance coupling strengths, to exert dynamical control capitalizing on backaction, and to provide sensitive probes. In this project we aim to explore the potential of a tunable THz to mid-infrared cavity for the control and spectroscopy of correlated transient or steady states of matter through the coupling to phononic and magnonic degrees of freedom in regimes where nonlinear couplings are crucial. We hypothesize that this interplay between coherent and incoherent processes enables control of the phase transitions in the 1D Mott insulators TiOCl and CuGeO3 in fundamentally new ways.
