The Lie algebra of the Lorentz group O(3,3) admits two types of SU(2) × / SU(2) subalgebras: a standard form based on spatial rotation generators and a second form based on temporal rotation generators. The units of measurement for the conserved quantity due to invariance under temporal rotations are investigated and found to be the same units...

This thesis project aims for the development of a demonstration platform on mobile devices for testing and demonstrating algorithms for 2D and 3D spatial sound reproduction. The demo system consists of four omnidirectional microphones in a square planar array, an Octo sound card (from Audio Injector), a Raspberry Pi 3B+ (R-Pi) single-board computer...

This author has replaced the Maxwell equations with the corresponding mutual energy principle, self-energy principle as the axioms in electromagnetic eld theory. The advantage of doing this is that it can overcome the diculty of the Maxwell equations, which conicts to the energy conservation law. The same conict also exists in the Schrödinger equat...

We review field theory studies devoted to understanding electron-electron interaction effects in condensed matter systems such as planar Dirac liquids, for example, graphene and graphene-like systems, surface states of some topological insulators, and possibly half-filled fractional quantum Hall systems. These liquids are characterized by gapless b...

The Planck units are defined from fundamental physical constants. Ontologically we note that the coupling constant, intrinsic to the Planck charge, generates on space-time the interlacing of the dimensioned constants ml, h, G, iterated in geometric progression of reason c, the speed of light. As alpha is also “the ratio of the velocity of the elect...

We map the 2+1 Dirac–Moshinsky oscillator (2+1 DMO) coupled to an external isospin field onto the Jaynes–Cummings model (JCM), which describes the interaction between two two-level systems and a quantum single-mode field. We obtain the time-dependent wave function and the density matrix in two cases. As an initial state, we consider the quantum num...

In the present article we investigate the spin-1/2 and spin-1 cases in different bases. Next, we look for relations with the Majorana-like field operator. We show explicitly incompatibility of the Majorana anzatzen with the Dirac-like field operators in both the original Majorana theory and its generalizations. Several explicit examples are present...

Les unités de Planck sont définies à partir de constantes physiques fondamentales. Ontologiquement nous constatons que la constante de couplage intrinsèque à la charge génère sur l’espace-temps l’entrelacs des constantes dimensionnées ml, h, G, itérées en progression géométrique de raison c, la vitesse de la lumière. Comme alpha est aussi le rati...

For photon we have obtained the results that the wave of photon obeys the mutual energy principle and self-energy principle. In this article we will extended this to other quantum. The mutual energy principle and self energy principle corresponding to the Schrödinger equation is introduced. The results is that a electron for example travel in the e...

The significance of the de Broglie/Bohm hidden-particle position in the relativistic regime is addressed, seeking connection to the (orthodox) single-particle Newton–Wigner position. The effect of non-positive excursions of the ensemble density for extreme cases of positive-energy waves is easily computed using an integral of the equations of motio...
