Role of intersublattice exchange interaction on ultrafast longitudinal and transverse magnetization dynamics in Permalloy
A. Maghraoui, F. Fras, M. Vomir +4
We report about element specific measurements of ultrafast demagnetization and magnetization precession damping in Permalloy (Py) thin films. Magnetization dynamics induced by opti…
Exploring coherence of individual excitons in InAs quantum dots embedded in natural photonic defects: influence of the excitation intensity
Daniel Wigger, Valentin Delmonte, Quentin Mermillod +10
The exact optical response of quantum few-level systems depends crucially on the exact choice of the incoming pulse areas. We use four-wave mixing (FWM) spectroscopy to infer the c…
Spin Textures of Polariton Condensates in a Tunable Microcavity with Strong Spin-Orbit Interaction
S. Dufferwiel, F. Li, E. Cancellieri +9
We report an extended family of spin textures in coexisting modes of zero-dimensional polariton condensates spatially confined in tunable open microcavity structures. The coupling…
Strong exciton-photon coupling in open semiconductor microcavities
S. Dufferwiel, F. Fras, A. Trichet +9
We present a method to implement 3-dimensional polariton confinement with in-situ spectral tuning of the cavity mode. Our tunable microcavity is a hybrid system consisting of a bot…
The effects of spin-dependent interactions on polarisation of bright polariton solitons
M. Sich, F. Fras, J. K. Chana +10
We report on the spin properties of bright polariton solitons supported by an external pump to compensate losses. We observe robust circularly polarised solitons when a circularly…
Effect of polariton-polariton interactions on the excitation spectrum of a non-equilibrium condensate in a periodic potential
D. N. Krizhanovskii, E. A. Cerda, S. S. Gavrilov +9
Polariton condensates are investigated in periodical potentials created by surface acoustic waves using both resonant and non-resonant optical excitation. Under resonant pumping co…
