Dirac and Majorana relativistic fermion fields\nby Valeriy Sbitnev (Berkeley) as part of QM Foundations & Nature of Time seminar\n\n\nAbstract\nGravitomagnetic eq uations result from applying quaternion differential operators to the ener gy-momentum tensor written in the quaternion basis. These equations are si milar to Maxwell’s EM equations. They are parent ones generating a serie s of equations describing the real physical processes. The vorticity equat ion gives solutions of vortices with nonzero vortex cores and infinite lif etime. The Hamilton-Jacobi equation loaded by the quantum potential opens the hydrodynamic approach on the fermionic fields. In the relativistic lim it\, this equation (together with the continuity one) underlies fermionic fields leading to the emergence of the Dirac equation. Analysis of its sol utions discloses the existence of the paired Majorana fermions having inte ger spins 1 or 0 as\, for example\, ortho- and para- hydrogens. One more solution of the Dirac equation leads to the existence of the particle-anti particle pair.\nThe electron-positron pairs ordered into a macroscopic coh erent Bose-Einstein condensate give a simple example of the existence of W ilczek's time crystals. The pairs of proton-antiprotons\, loaded by accomp anying electron-positron buffers\, can pose long-lived ordered quantum ob jects. These objects representing the Bose-Einstein condensate look like W ilczek's time crystals as well.\nThese macroscopic coherent ensembles are discussed in the light of the ball lightning manifestations capable of tun neling across hard obstacles\, for example\, window glasses.\n LOCATION:https://researchseminars.org/talk/QMFNoT/37/ END:VEVENT END:VCALENDAR
