Dynamical chiral symmetry breaking by a magnetic field in QED.
It is shown that the chiral symmetry is spontaneously broken by a constant magnetic field in QED. The dynamical mass of fermions (energy gap in the fermion spectrum) is mdyn ≃ C √ eB exp [
متن کاملChiral Symmetry Breaking in Three Dimensional QED
Over the past few years three dimensional Quantum Electrodynamics (QED3) has attracted a lot of attention, because it may be an effective theory for the underdoped and nonsuperconducting region of the phase diagram of high Tc cuprate compounds. We present results from lattice simulations of the non-compact version of the theory in order to address the issue of whether chiral symmetry is spontan...
متن کاملChiral Symmetry Breaking in Strongly Coupled Qed?
The coupled system of renormalized Dyson-Schwinger equations for the electron self-energy and the photon propagator are supplied with the tree level vertex as Ansatz for the renormalized three point function. The system is investigated numerically. In the case of a massive electron, the theory is " weakly renormalizable " , i.e. cutoff independent for values of the cutoff below an upper limit. ...
متن کاملDynamical Electroweak Symmetry Breaking
These lectures explored the idea that the physics of electroweak symmetry breaking arises from novel strong dynamics. We started from the familiar strong-interaction dynamics of QCD, introduced simple dynamical electroweak symmetry breaking models whose strong dynamics imitate those of QCD, analyzed the limitations of these models, and finally moved on to theories whose dynamics differ from tho...
متن کاملDynamical Electroweak Symmetry Breaking
We review the status of and recent developments in dynamical electroweak symmetry breaking, concentrating on the ideas of technicolour and top quark condensates. The emphasis is on the essential physical ideas and experimental implications rather than on detailed mathematical formalism. After a general overview of the subject, we give a first introduction to technicolour, and extended technicol...
