Delayed Formation of Landau Polaritons in Phase-Resolved THz Spectroscopy
Noureddine Charrouj, Yurii Ivonyak, Dmitriy Yavorskiy +4
Strong light-matter coupling gives rise to polaritons through coherent and periodic energy exchange between electromagnetic cavity fields and material excitations. While this inter…
Constriction-induced modulation of charging energy in a quantum Hall cavity
Emily Hajigeorgiou, Arup Kumar Paul, Mario Di Luca +3
Electronic Fabry-Pérot interferometers (FPIs) operating in the fractional quantum Hall regime are a key platform for probing anyonic braiding statistics, yet interpreting their in…
Coherence, long-range transport and nuclear polarization in a driven-dissipative dark exciton condensate
Amit Jash, Maheswar Swar, Uri Shimon +2
We report direct evidence for macroscopic coherence in a condensate of dark dipolar excitons in coupled quantum wells and show that its formation follows a non-equilibrium, driven-…
Nature of current flow in the regime of the quantum Hall effect
Serkan Sirt, Matthias Kamm, Vladimir Y. Umansky +1
The integer quantum Hall effect (QHE) belongs to the most fundamental phenomena of solid state physics and has an important application as resistance standard. It serves as a basis…
Transition from edge- to bulk-currents in the quantum Hall regime
Serkan Sirt, Vladimir Y. Umansky, Afif Siddiki +1
The integer quantum Hall effect can be observed in a two-dimensional conductor penetrated by a perpendicular magnetic field and with edges connecting the current carrying contacts.…
