Absence of a Superradiant Phase Transition in Dirac Landau Polaritons
Elsa Jöchl, Felix Helmrich, Frieder Lindel +6
One of the most striking predictions in cavity quantum electrodynamics is the condensation of photons into a macroscopically populated ground state, the so-called superradiant phas…
Cavity modification of magnetoplasmon mode through coupling with intersubband polaritons
Lucy L. Hale, Daniele De Bernardis, Stephan Lempereur +12
We investigate the coupling of a multi-mode metal-insulator-metal cavity to a two-dimensional electron gas (2DEG) in a quantum well in the presence of a strong magnetic field. The…
Multi-mode Deep Strong Coupling in a Multi Quantum Well Fabry-Perot Cavity
Lucy Hale, Johan Andberger, Ethan Koskas +4
We present multi-mode deep-strong coupling in a multi-quantum well (N=166) heterostructure. The heterostructure itself acts as a Fabry-Perot cavity, for which the even cavity modes…
Gate-tunable single terahertz meta-atom ultrastrong light-matter coupling
Elsa Jöchl, Anna-Lydia Vieli, Lucy Hale +6
We study the electrical tunability of ultrastrong light-matter interactions between a single terahertz circuit-based complementary split ring resonator (cSRR) and a two-dimensional…
