The prospect of controlling the electronic properties of materials via the vacuum fields of
cavity electromagnetic resonators is emerging as one of the frontiers of condensed matter …

Hybrid excitations, called polaritons, emerge in systems with strong light–matter coupling.
Usually, they dominate the linear and nonlinear optical properties with applications in …

Ultrastrong light-matter coupling allows the exploration of new states of matter through the
interaction of strong vacuum fields with huge electronic dipoles. By using hybrid dipole …

The value of fundamental physical constants is affected by the coupling of matter to the
electromagnetic vacuum state, as predicted and explained by quantum electrodynamics. In …

The achievement of large values of the light–matter coupling in nanoengineered photonic
structures can lead to multiple photonic resonances contributing to the final properties of the …

We present a theory predicting how the linear magnetotransport of a two-dimensional (2D)
electron gas is modified by a passive electromagnetic cavity resonator where no real …

Light and matter can strongly mix together to form hybrid particles called polaritons. In recent
years, polaritons in the so-called ultrastrong coupling (USC) regime have attracted much …

Light–matter interaction in the ultrastrong coupling regime is attracting considerable
attention owing to its applications to coherent control of material properties by a vacuum …

We demonstrate terahertz chiral metamaterial cavities that break time-reversal symmetry by
coupling the degenerate linearly polarized modes of two orthogonal sets of nano-antenna …

Placed in cavity resonators with three-dimensionally confined electromagnetic wave, the
interaction between quasiparticles in solids can be induced by exchanging virtual cavity …
