Optical pumping of electronic quantum Hall states with vortex light
Deric Session, Mahmoud Jalali Mehrabad, Nikil Paithankar +13
A fundamental requirement for quantum technologies is the ability to coherently control the interaction between electrons and photons. However, in many scenarios involving the inte…
Chiral transport of hot carriers in graphene in the quantum Hall regime
Bin Cao, Tobias Grass, Olivier Gazzano +12
Photocurrent (PC) measurements can reveal the relaxation dynamics of photo-excited hot carriers beyond the linear response of conventional transport experiments, a regime important…
Optical flux pump in the quantum Hall regime
Bin Cao, Tobias Grass, Glenn Solomon +1
A seminal gedankenexperiment by Laughlin describes the charge transport in quantum Hall systems via the pumping of flux. Here, we propose an optical scheme which probes and manipul…
Observation of chiral photocurrent transport in the quantum Hall regime in graphene
Olivier Gazzano, Bin Cao, Jiuning Hu +6
Optical excitation provides a powerful tool to investigate non-equilibrium physics in quantum Hall systems. Moreover, the length scale associated with photo-excited charge carries…
