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…
Fluctuation engineering in cavity quantum materials
Hope M Bretscher, Lorenzo Graziotto, Marios H Michael +14
Coupling tailored electromagnetic fluctuations to materials provides a resource for controlling correlated quantum matter. By structuring the frequency, spatial, and modal distribu…
Cavity QED Control of Quantum Hall Stripes
Lorenzo Graziotto, Josefine Enkner, Sambuddha Chattopadhyay +7
Controlling quantum phases of materials with vacuum field fluctuations in engineered cavities is a novel route towards the optical control of emergent phenomena. We demonstrate, us…
Enhanced fractional quantum Hall gaps in a two-dimensional electron gas coupled to a hovering split-ring resonator
Josefine Enkner, Lorenzo Graziotto, Dalin Boriçi +7
The magnetotransport of a high-mobility two-dimensional electron gas coupled to a hovering split-ring resonator with controllable distance is studied in the quantum Hall regime. Th…
Testing the Renormalization of the von Klitzing Constant by Cavity Vacuum Fields
Josefine Enkner, Lorenzo Graziotto, Felice Appugliese +7
In light of recent developments demonstrating the impact of cavity vacuum fields inducing the breakdown of topological protection in the integer quantum Hall effect, a compelling q…
Theory of infrared double-resonance Raman spectrum in graphene: the role of the zone-boundary electron-phonon enhancement
Lorenzo Graziotto, Francesco Macheda, Thibault Sohier +2
We theoretically investigate the double-resonance Raman spectrum of monolayer graphene down to infrared laser excitation energies. By using first-principles density functional theo…
