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…

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…
