Spin polarisation signatures of Fractionally Charged Skyrmions in Fractional Quantum Hall states
Odysseas Williams, Stefan Faelt, Christian Reichl +1
We investigate spin polarisation and low-energy excitations in fractional quantum Hall (FQH) states using cavity-polariton spectroscopy of high-mobility GaAs quantum wells. By meas…
Spin polarization of Quantum Hall states for filling factors 1 < v < 2 measured with microcavity polaritons
Odysseas Williams, Stefan Faelt, Filip Krizek +1
Spin polarization measurements were performed in three 2D Electron Gases in GaAs with densities n = 9.1, 7.2 and 6.5 x10^10 cm-2, in the quantum Hall regime. Full spin polarization…
Spin-selective strong light-matter coupling in a 2D hole gas-microcavity system
Daniel G. Suarez-Forero, Deric Weston Session, Mahmoud Jalali Mehrabad +4
The interplay between time-reversal symmetry breaking and strong light-matter coupling in 2D gases brings intriguing aspects to polariton physics. This combination can lead to pola…
A polariton electric field sensor
Emre Togan, Yufan Li, Stefan Faelt +2
We experimentally demonstrate a dipolar polariton based electric field sensor. We tune and optimize the sensitivity of the sensor by varying the dipole moment of polaritons. We sho…
Strong interactions between dipolar polaritons
Emre Togan, Hyang-Tag Lim, Stefan Faelt +2
Nonperturbative coupling between cavity photons and excitons leads to formation of hybrid light-matter excitations termed polaritons. In structures where photon absorption leads to…
Squeezed thermal reservoirs as a resource for a nano-mechanical engine beyond the Carnot limit
Jan Klaers, Stefan Faelt, Atac Imamoglu +1
The efficient conversion of thermal energy to mechanical work by a heat engine is an ongoing technological challenge. Since the pioneering work of Carnot, it is known that the effi…
