A Classical version of the Einstein-de Haas Effect
نویسنده
چکیده
The Einstein-de Haas effect is a striking example of macroscopic manifestation of microscopic quantum phenomena, in this case magnetization of electron orbital and intrinsic spins in a ferromagnetic rod by an external magnetic field that leads to a net global angular momentum having to be compensated by an opposing twist in the rod. This letter gives a system consisting of a rotating fluid layer coupled to a massive sphere which displays a classical version of the Einsteinde Haas effect, is simple enough to be solved exactly for phase transitions, and is relevant to some large-scale phenomena in planetary atmospheres.

Einstein-de Haas effect in dipolar Bose-Einstein condensates.
The general properties of the order parameter for a dipolar spinor Bose-Einstein condensate are discussed based on symmetries of interactions. An initially spin-polarized dipolar condensate is shown to dynamically generate a nonsingular vortex via spin-orbit interactions--a phenomenon reminiscent of the Einstein-de Haas effect in ferromagnets.
متن کاملQuantum Einstein-de Haas effect
The classical Einstein-de Haas experiment demonstrates that a change of magnetization in a macroscopic magnetic object results in a mechanical rotation of this magnet. This experiment can therefore be considered as a macroscopic manifestation of the conservation of total angular momentum and energy of electronic spins. Since the conservation of angular momentum is a consequence of a system's ro...
متن کاملOn the Einstein-de Haas and Barnett Effects
The orthogonal relation between the magnetic aspect (spin) of scatterable elementary particles’ energy with respect to their direction of motion can be demonstrated at the macroscopic level by mechanical means. It can be proven that force aligning the spins of unpaired electrons in ferromagnetic materials causes the unidirectional carrying energy of the electrons involved to align orthogonally ...
متن کاملThe Intrinsic Beauty, Harmony and Interdisciplinarity in Einstein Velocity Addition Law: Gyrogroups and Gyrovector Spaces
The only justification for the Einstein velocity addition law appeared to be its empirical adequacy, so that the intrinsic beauty and harmony in Einstein addition remained for a long time a mystery to be conquered. Accordingly, the aim of this expository article is to present (i) the Einstein relativistic vector addition, (ii) the resulting Einstein scalar multiplication, (iii) th...
متن کاملResonant Einstein-de Haas effect in a rubidium condensate.
We theoretically consider a spin polarized, optically trapped condensate of 87Rb atoms in F=1. We observe a transfer of atoms to other Zeeman states due to the dipolar interaction which couples the spin and the orbital degrees of freedom. Therefore the transferred atoms acquire an orbital angular momentum. This is a realization of the Einstein-de Haas effect in systems of cold gases. We find re...
