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…
Large-bandwidth transduction between an optical single quantum-dot molecule and a superconducting resonator
Yuta Tsuchimoto, Zhe Sun, Emre Togan +6
Quantum transduction between the microwave and optical domains is an outstanding challenge for long-distance quantum networks based on superconducting qubits. For all transducers r…
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…
Spin Reversal of a Quantum Hall Ferromagnet at a Landau Level Crossing
M. Lupatini, P. Knüppel, S. Faelt +4
When Landau levels (LLs) become degenerate near the Fermi energy in the quantum Hall regime, interaction effects can drastically modify the electronic ground state. We study the qu…
