Comments on Exploring Quantum Statistics for Dirac and Majorana Neutrinos using Spinor-Helicity technique (arXiv:2507.07180 [hep-ph])
We give our comments on Ref. [1](arXiv:2507.07180) which critiques our idea of exploring quantum statistics to distinguish between Dirac and Majorana neutrinos proposed in some of our earlier works. We show that the ad-hoc symmetrization of the Dirac case amplitude square advocated in Eqs. (16) and (35) of [1], have no physical basis and it leads to violation of lepton number in the the standard model. Therefore, we consider this symmetrization by hand as incorrect and misleading. Moreover, we …

Mixed gauge-gravity term and proper time
We consider the four-dimensional action of spinors minimally coupled to a $U(1)$-gauge field in an Riemann-Cartan background. In this theory, we integrate over the spinors and study the resulting one-loop gauge-gravity effective action, paying special attention to the contributions that depend on both the gauge field and the torsion. We explicitly calculate the gauge-torsion term, which turns out to be finite, and comment on possible terms depending simultaneously on torsion, curvature, and gau…

A sublattice Stokes polarimeter for bipartite photonic lattices
The concept of pseudo-spin provides a general framework for describing physical systems featuring two-component spinors, including light polarization, sublattice degrees of freedom in bipartite lattices, and valley polarization in 2D materials. In all cases, the pseudo-spin can be mapped to a Stokes vector on the Poincaré sphere. Stokes polarimeters for measuring the polarization of light are a powerful tool with a wide range of applications both in classical and quantum science. Generalizing …

Seven Sphere Quantization
Co-oriented contact manifolds quite generally describe classical dynamical systems. Quantization is achieved by suitably associating a Schrödinger equation to every path in the contact manifold. We quantize the standard contact seven sphere by treating it as a homogeneous space of the quaternionic unitary group in order to construct a contact analog of Fedosov's formal connection on symplectic spinor bundles. We show that requiring convergence of the formal connection naturally filters the sym…

Much of what is going on under the present FFOTUS/maga-klan/white-christian-nationalist reign reminds me of a time in Florence, Italy in the late 1400s.
A nut named Girolamo Savonarola tried to impose a very regressive Christian policy onto Florence.
The people of Florence didn't like it and, in the end, gave Savonarola a rather hot time.
