Placing quantum materials into optical cavities provides a unique platform for controlling
quantum cooperative properties of matter, by both weak and strong light–matter coupling …

In the majority of optoelectronic devices, emission and absorption of light are considered as
perturbative phenomena. Recently, a regime of highly non-perturbative interaction, ultra …

All-to-all interacting, disordered quantum many-body models have a wide range of
applications across disciplines, from spin glasses in condensed-matter physics over …

Controlling the topological properties of quantum matter is a major goal of condensed matter
physics. A major effort in this direction has been devoted to using classical light in the form of …

We demonstrate that collective vibrational strong coupling of molecules in thermal
equilibrium can give rise to significant local electronic polarizations in the thermodynamic …

Polaritons are light-matter quasiparticles that govern the optical response of quantum
materials at the nanoscale, enabling on-chip communication and local sensing. Here, we …

The hybridization between light and matter forms the basis to achieve cavity control over
quantum materials. In this Letter we investigate a cavity coupled to a quantum chain of …
