Williamson (Universit y of Glasgow) as part of QM Foundations & Nature of Time seminar\n\n\nAbst ract\nDirac's theory has been the "gold standard" of relativistic quantum mechanics (RQM) for more than ninety years. During that time the quantum m echanics used in the imagining and engineering of quantum devices has been in the realm of\, almost exclusively\, the non-relativistic Schroëdinger theory using complex wave-functions.\n\nThe merely complex is\, however\, too simple to properly represent covariant\, relativistic wave-functions. Furthermore\, the merely complex cannot properly represent intrinsic rela tivistic quantum properties such as the intrinsic spin. If one does not ha ve the proper theory\, the internal behaviour of the elementary particles\ , their mutual inter-actions\, and the very quantum properties of collecti ve quantum systems\, such as high-temperature superconductors\, cannot be properly thought about at all.\n\nThe new theory presented here aims to r ectify those deficiencies: it treats the elementary particle masses in a f undamentally different way to Dirac\, incorporating them as a pair of elem ents within a hypercomplex algebra including both the complex algebra\, an d the quaternion algebra as sub-algebras. This allows a simpler\, and even more beautiful equation than the Dirac or Maxwell equations to be written down\, which yet contains them both. This equation may be written simply as dG=C\, where "d" is a relativistic space-time derivative\, "G" is a six teen component multi-vector\, and "C" is a sixteen component array of real constants\, most of which are zero.\n\nThe new theory opens up new vistas \, new thinking\, and new connections. It provides an underlying basis to the theory of Quantum ElectroDynamics\, encompasses the Newton\, Maxwell a nd Einstein\, and removes all of the outstanding problems in RQM.\n\nThe t alk will focus on answering the list of questions posed by the group (repe ated below)\, as well as a set of further fundamental questions\, includin g the origin of the g-2 term in the theory. This will include the nature o f the "generations" of particles in the standard model. It is argued that the addition of this new element to the "standard model" will allow one to promote to a "standard theory" fit for progressing the new challenges of the 21st century.\n\nQuestions to be answered include\, but are not limite d to:\n\nWhy electric charge is quantized.\nWhere the Coulomb interaction comes from\nHow one can prevent infinites e.g. of electric field of a poin t charge\nOrigins of the induced magnetic dipole and the intrinsic angular momentum\nOrigin of the zitterbewegung/clock of the electron\nWhy we have 3 generations of leptons\nWhy the proton is lighter than neutron\nWhat ho lds nuclei together against the Coulomb force\nWhat holds charged elementa ry particles together against the enormous Coulomb repulsion\nHow to get g ravity from relativistic quantum mechanics and Q.E.D.\n\nThe talk will foc us on answering the list of questions posed by the group\, including the n ature and origin of charge\, the reason for and the nature of the "generat ions" of particles in the standard model. It is argued that the addition o f this new element to the "standard model" will allow one to promote to a "standard theory" fit for progressing the new challenges of the 21st centu ry.\n LOCATION:https://researchseminars.org/talk/QMFNoT/41/ END:VEVENT END:VCALENDAR
