Engineering Biquadratic Interactions in Spin-1 Chains by Spin-1/2 Spacers
Yasser Saleem, Weronika Pasek, Marek Korkusinski +2
Low-dimensional quantum systems host a variety of exotic states, such as symmetry-protected topological ground states in spin-1 Haldane chains. Real-world realizations of such stat…

Magnetotransport Spectroscopy of Strongly Rashba-Split Hole Subbands Reveals Many-Body Interactions
F. Sfigakis, N. A. Cockton, M. Korkusinski +13
We report the results of magnetotransport experiments carried out on low-disorder 2D hole gases (2DHG) in the strongly correlated liquid regime, hosted in dopant-free (100) GaAs/Al…

Enhanced effective masses, spin-orbit polarization, and dispersion relations in 2D hole gases under strongly asymmetric confinement
N. A. Cockton, F. Sfigakis, M. Korkusinski +13
The dispersion of Rashba-split heavy-hole subbands in GaAs two-dimensional hole gases (2DHGs) is difficult to access experimentally because strong heavy-hole-light-hole mixing prod…
