Measurable fractional spin for quantum Hall quasiparticles on the disk
Tommaso Comparin, Alvin Opler, Elia Macaluso +3
We study the spin of the localised quasiparticle excitations of lowest-Landau-level quantum Hall states defined on a disk. The spin that we propose satisfies the spin-statistics re…
Spin squeezing from bilinear spin-spin interactions: two simple theorems
Tommaso Roscilde, Fabio Mezzacapo, Tommaso Comparin
We demonstrate two simple theorems about squeezing induced by bilinear spin-spin interactions that conserve spin parity -- including a vast majority of quantum spin models implemen…
Robust spin squeezing from the tower of states of -symmetric spin Hamiltonians
Tommaso Comparin, Fabio Mezzacapo, Tommaso Roscilde
Spin squeezing - a central resource for quantum metrology - can be generated via the non-linear, entangling evolution of an initially factorized spin state. Here we show that robus…
