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…

Terahertz chiral sub-wavelength cavities breaking time-reversal symmetry via ultra-strong light-matter interaction

Johan Andberger, Lorenzo Graziotto, Luca Sacchi +3

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

An engineered planar plasmonic reflector for polaritonic mode confinement

Shima Rajabali, Josefine Enkner, Erika Cortese +4

It was recently demonstrated that, in deep subwavelength gap resonators coupled to two-dimensional electron gases, coupling to propagating plasmons can lead to energy leakage and p…

Breakdown of the topological protection by cavity vacuum fields in the integer quantum Hall effect

Felice Appugliese, Josefine Enkner, Gian Lorenzo Paravicini-Bagliani +6

The control of the electronic properties of materials via the vacuum fields of cavity electromagnetic resonators is one of the emerging frontiers of condensed matter physics. We sh…
