چکیده
We investigate the mechanical structure of a spin-1 particle. Introducing three different frameworks, i.e., three-dimensional (3D) Breit frame, two-dimensional (2D) and 2D infinite momentum frame (equivalently Drell-Yan frame), we scrutinize 3D energy-momentum tensor (EMT) distributions in these frames. first derive EMT by performing Abel transformation. The mass distribution contains an additional monopole contribution induced geometrically. pressure also gets structure. When Lorentz boost is carried out, infinite-momentum acquires dipole term. Similarly, have contributions to shear-force densities. visualize when particle polarized along $x$- $z$-axes. observe that exhibit clearly $x$-axis. discuss strong force fields inside

Quantum Mechanical Embedding of Spinning Particle and Induced Spin-connection
This paper introduces the way of the embedding of spinning particle quantum mechanically for non-relativistic case. Schrödinger equation on its submanifold obtains the gauge field as spin connection, and it reduces to the ones obtained by Ohnuki and Kitakado when we consider S in R. PACS numbers: 03.65 1 Hypothesis and Schrödinger equation Let us consider the motion of non-relativistic spinning...

1 2 particle in an arbitrary magnetic field in two spatial dimensions: a supersymmetric quantum mechanical system Abstract It is shown that the 2 × 2 matrix Hamiltonian describing the dynamics of a charged spin 1/2 particle with g-factor 2 moving in an arbitrary, spatially dependent, magnetic field in two spatial dimensions can be written as the anticommuator of a nilpotent operator and its her...

15 صفحه اولThe particle interpretation of N=1 supersymmetric spin foams
Whilst supergravity theories go a certain way to tame the infinities of their non-supersymmetric cousins, they also generalise these theories by coupling fermionic degrees of freedom to the original gravity theory. One can easily see this at the continuum classical level. We want to investigate this issue in the discrete quantum case. Thus, in this paper, we shall analyze a rather simplified mo...
