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…
