چکیده
Abstract To understand the mechanism of the fermion pair and fermion-antifermion pair condensation,existence of the solutions of Bethe-Salpeter equation in QED3 is examined.In the ladder appoximation our solution for the axialscalar is consistent with Ward-Takahashi-identity for the axial vector currents.In addition to massless psedoscalar fermion-antifermion (fa) system there exists solutions for massless scalar-vector fermion-antifermion (fa) system with discrete spectrum,where the coupling constant mass ratio e2/4πm is quantized.In our approximation massless-scalar-vector ff systemes does not seem to exist.

The Feynman-Schwinger representation is used to study the behavior of solutions of scalar QED in (2+1) dimensions. The limit of zero photon mass is seen to be smooth. The Bethe-Salpeter equation in the ladder approximation also exhibits this property. They clearly deviate from the behavior in the non-relativistic limit. In a variational analysis we show that this difference can be attributed to...

We present an octonionic N = 1 superfield action that reproduces in components the action of Bagger and Lambert for M2 branes. By giving an expectation value to one of the scalars we obtain the maximally supersymmetric superfield action for D2 branes.

The e −-e + bound state spectrum of QED3 is investigated in the quenched ladder approximation to the homogeneous Bethe-Salpeter equation with fermion propagators from a Rainbow approximation Schwinger-Dyson solution with variable fermion mass. A detailed analysis of the analytic structure of the fermion propagator is performed so as to test the appropriateness of the methods employed. The large...

We study chiral symmetry breaking in quenched QED 4 , using a vertex Ansatz recently proposed by Curtis and Pennington. Bifurcation analysis is employed to establish the existence of a critical coupling and to estimate its value. The main results are in qualitative agreement with the ladder approximation, the numerical changes being minor.

A system of SU(N)-matrix difference equations is solved by means of a nested version of a generalized Bethe Ansatz, also called ”off shell” Bethe Ansatz [1]. The highest weight property of the solutions is proved.
