Ultrastrong Coupling of the Cyclotron Transition of a 2D Electron Gas to a THz Metamaterial
Ultrastrong Coupling of the Cyclotron Transition of a 2D Electron Gas to a THz Metamaterial
Artificial cavity photon resonators with ultrastrong light-matter interactions are attracting interest both in semiconductor and superconducting systems, due to the possibility of manipulating the cavity quantum electrodynamic ground state with controllable physical properties. We report here experiments showing ultrastrong light-matter coupling in a terahertz metamaterial where the cyclotron transition of …
