The spinorial ball (II): a manipulable qubit at human scale
Samuel Bernard-Bernardet, Benjamin Apffel
The spinorial ball is an electronic manipulable device that we recently introduced to discuss the origin of spin-1/2 from rotations group representation, without relying on the qua…

The spinorial ball: a macroscopic object of spin-1/2
Samuel Bernard-Bernardet, David Dumas, Benjamin Apffel
Historically, the observation of half-spin particles was one of the most surprising features of quantum mechanics. They are often described as "objects that do not come back to the…

Spontaneous emergence of a spin state for an emitter in a time-varying medium
Samuel Bernard-Bernardet, Marc Fleury, Emmanuel Fort
Time varying media can dramatically modify the emission of embedded sources by producing time reversed waves refocusing on the source. Here we show that such a back action can crea…
