Dipole-like dynamical nuclear spin polarization around a quantum point contact

Peter Stano, Tomosuke Aono, Minoru Kawamura

We theoretically investigate the dynamical nuclear spin polarization in a quantum point contact (QPC) at finite magnetic field. We find that when the QPC is tuned to be spin select…

Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids

A. Marciniak, P. Bartczak, T. Müller +40

The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. As a consequence of these select…
