Polarization in Attraction-Repulsion Models

Emmanuel Abbé

This paper introduces a model for opinion dynamics, where at each time step, randomly selected agents see their opinions - modeled as scalars in [0, 1] - evolve depending on a local interaction function. In the classical Bounded Confidence Model, agents op ...

Spin filtering neutrons with a proton target dynamically polarized using photo-excited triplet states

Tim Rolf Eichhorn

In a test of principle a neutron spin filter has been built, which is based on dynamic nuclear polarization (DNP) using photo-excited triplet states. This DNP method has advantages over classical concepts as the requirements for cryogenic equipment and mag ...

Optical bistability in InGaN-based multisection laser diodes

Nicolas Grandjean, Jean-François Carlin, Dmitri Boiko, Julien Dorsaz, Luca Alex Milo Sulmoni

Optical bistability is observed in cw-operating InGaN-based laser diodes including a saturable absorber (SA) section. The dependence of the light-current hysteresis on the SA section length and reverse bias (VSA) has been studied. An analytical approach is ...
