Functional Callan-symanzik Equation for Qed
An exact evolution equation, the functional generalization of the CallanSymanzik method, is given for the effective action of QED where the electron mass is used to turn the quantum fluctuations on gradually. The usual renormalization group equations are recovered in the leading order but no Landau pole appears. Introduction: The idea of dimensional transmutation [1] is that a dimensionless par...
متن کاملSolutions of Bethe - Salpeter equation in QED
Abstract To understand the mechanism of the fermion pair and fermion-antifermion pair condensation,the solutions of Bethe-Salpeter equation in QED3 is examined.In the ladder appoximation our solution for the axial-scalar is consistent with Ward-Takahashi-identity for the axial vector currents.Since the massless scalar-vector sector is described by a coupled integral equation,it is difficult to ...
متن کاملOn wave functional in QED
In a discrete form of the second quantization, the gauge independencies of all the physical states including vacuum in QED are restudied through a new approach. We also discuss an interesting phenomenon attributed to vacuum effect and come up with a procedure to produce general physical states. PACS: 03.65.Db, 12.70.Ds
متن کاملSeeking the Equation of State of Non-compact Lattice Qed Seeking the Equation of State of Non-compact Lattice Qed
We perform a high statistics calculation of the equation of state for non-compact QED on large lattices. The calculation extends to fermionic correlation lengths of 8, and it is combined with a nite size scaling analysis of the lattice data.
متن کاملOn Hilbert Golab-Schinzel type functional equation
Let $X$ be a vector space over a field $K$ of real or complex numbers. We will prove the superstability of the following Go{l}c{a}b-Schinzel type equation$$f(x+g(x)y)=f(x)f(y), x,yin X,$$where $f,g:Xrightarrow K$ are unknown functions (satisfying some assumptions). Then we generalize the superstability result for this equation with values in the field of complex numbers to the case of an arbitr...
