Spin-charge separation for paired Dirac fermions in (1 + 1) dimensions
Journal of High Energy PhysicsWe study Dirac fermions at finite density coupled to a complex pairing field assumed to obey scalar field theory with quartic self-repulsion. The bulk of our work develops the mathematics that elucidates the propagation of fermionic excitations in such ...

Shape operator of an $ (n-1) $-dimensional distribution on an $ n $-dimensional manifold and their classification [PDF]
ریاضی و جامعهThis paper aims to study of shape operator of an $ (n-1) $-dimensional distribution on an $ n $-dimensional smooth manifold. In this study firstly we state formulae for the shape operator and its symmetric and anti-symmetric components and in ...

Advanced Engineering Materials, EarlyView.This study examines the mechanical properties of triply periodic minimal surfaces (TPMS)‐based lattices, analyzing 36 architectures in elastic and plastic regimes. It evaluates the applicability of beam‐based scaling laws to TPMS lattices. Rigidity arises from the alignment of members with the load direction and solid regions preventing rotation.

Huygens' Principle for the Non-Self-Adjoint Scalar Wave Equation on Petrov type III Space-Times [PDF]
Ann. Inst. Henri Poincare (A) Phys. Theorique 70, 259 (1999), 2005 We prove that if the non-self-adjoint scalar wave equation satisfies Huygens' principle on Petrov type III space-times, then it is equivalent to the conformally invariant scalar wave equation.

Advanced Engineering Materials, EarlyView.Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Complete Solution of Hadamard's Problem for the Scalar Wave Equation on Petrov type III Space-Times [PDF]
Ann. Inst. Henri Poincare (A) Phys. Theorique 71, 595-620 (1999), 2005 We prove that there are no Petrov type III space-times on which the conformally invariant (self-adjoint) scalar wave equation or the non-self-adjoint scalar wave equation satisfies Huygens' principle.

Advanced Engineering Materials, EarlyView.This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,

More Mathematical Proofs To Define A Unified Scalar Theory
The purpose of this paper is to serve as a computational proof of concept for my "Unified Theory Of Scalability". The contents of this paper show an extended framework for the intitial logic pattern that was described in the original super formula Z = (X•(A/B)•Y)^tWhere the bounds of the system are set to where the highest and lowest order ...
