Composite Operator Effective Potential Approach to Qed 3
نویسندگان
چکیده
The composite operator effective potential is compared with the conventional Dyson–Schwinger method as a calculational tool for (2+1)-dimensional quantum electrodynamics. It is found that when the fermion propagator ansatz is put directly into the effective potential, it reproduces exactly the usual gap equations derived in the Dyson–Schwinger approach.

The effective potential of composite fields in weakly coupled QED in a uniform external magnetic field
The effective potential for the composite fields responsible for chiral symmetry breaking in weakly coupled QED in a magnetic field is derived. The global minimum of the effective potential is found to acquire a non-vanishing expectation value of the composite fields that leads to generating the dynamical fermion mass by an external magnetic field. The results are compared with those for the Na...
متن کاملEffective Dynamics of an Electron Coupled to an External Potential in Non-relativistic Qed
In the framework of non-relativistic QED, we establish the relationship between the renormalized mass of the electron due to its interaction with the quantized electromagnetic field, and the kinematic mass appearing in its response to a slowly varying external force. Specifically, we study the dynamics of an electron in a slowly varying external potential and with slowly varying initial conditi...
متن کاملFermion Determinants 2003
It is recommended that lattice QCD representations of the fermion determinant, including the discretization of the Dirac operator, be checked in the continuum limit against known QED determinant results. Recent work on the massive QED fermion determinant in two dimensions is reviewed. A feasible approach to the four-dimensional QED determinant with O(2) × O(3) symmetric background fields is bri...
متن کاملAn Effective Potential for Composite Operators
We study the effective potential for composite operators. Introducing a source coupled to the composite operator, we define the effective potential by a Legendre transformation. We find that in three or fewer dimensions, one can use the conventionally defined renormalized operator to couple to the source. However, in four dimensions, the effective potential for the conventional renormalized com...
متن کاملSu(n) Antiferromagnets and the Phase Structure of Qed in the Strong Coupling Limit
We examine the strong coupling limit of both compact and non-compact quantum electrodynamics (QED) on a lattice with staggered Fermions. We show that every SU(NL) quantum antiferromagnet with spins in a particular fundamental representation of the SU(NL) Lie algebra and with nearest neighbor couplings on a bipartite lattice is exactly equivalent to the infinite coupling limit of lattice QED wit...
