Momentum Distribution Critical Exponents for 1D Hubbard model in a Magnetic Field
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 0, Vol 11, Issue 3
Abstract
Critical exponents at and for the momentum distribution function are studied for one-dimensional Hubbard model in the presence of magnetic field, using conformal field theory (CFT) approach. Exponents at and are reproduced. Results at is in contrast to earlier numerical prediction of 1, while at , the exponent is 49/8. The singularities at and appears to be weak and gradually degenerating into a smooth curve.

A Study on Formation of Hammer Transfer Stains in a Crime Scene
It is difficult to interpret hammer transfer strain in a crime scene. This paper lies in the argument that proper analysis of hammer transfer stains in crime scene may indicate the possibilities of proper incidence.
Superconducting String Theory (Gravity explanation)
The ˜Theory of Everything is hypothetical theory of physics that explains and connects all known physical phenomena into one. After study, I have reached to a solution that describes the origin of gravitat...
The necessary and sufficient condition for the stability of a rigid body
In this paper, the stability of the unperturbed rigid body motion close to conditions, related with the center of mass, is investigated. The three first integrals for the equations of motion are obtained. These integrals...

Deformation potentials eV and eV for ∆1 minimum of conduction band of single crystals  n-Ge are defined on the basis of theory of the anisotropic scattering and experimental data of longitudinal piezo resis...
Multiple and least energy sign-changing solutions for Schrodinger-Poisson equations in R3 with restraint
In this paper, we study the existence of multiple sign-changing solutions with a prescribed Lp+1−norm and theexistence of least energy sign-changing restrained solutions for the following nonlinear Schr¨odinger-Poisso...
