Spontaneous breaking of Lorentz symmetry in (2+1)-dimensional QED
The phase diagram of quantum electrodynamics in three space-time dimensions as a function of fermion flavor number N exhibits two well-known phases: at large N > N c the system is in a conformal state with anomalous exponents, while for small N < N c the fermions are expected to develop a dynamical mass due to spontaneous chiral symmetry breaking. Using expansion near the lower critical dimensi...
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 کاملFour-dimensional M-theory and supersymmetry breaking
We investigate compactifications of M -theory from 11 → 5 → 4 dimensions and discuss geometrical properties of 4-d moduli fields related to the structure of 5-d theory. We study supersymmetry breaking by compactification of the fifth dimension and find that an universal superpotential is generated for the axion-dilaton superfield S. The resulting theory has a vacuum with < S >= 1, zero cosmolog...
متن کاملLorentz-Invariant Non-Commutative QED
Lorentz-invariant non-commutative QED (NCQED) is constructed such that it should be a part of Lorentz-invariant non-commutative standard model (NCSM), a subject to be treated in later publications. Our NCSM is based on Connes’ observation that the total fermion field in the standard model may be regarded as a bi-module over a flavorcolor algebra. In this paper, it is shown that there exist two ...
متن کاملSpontaneous chiral-symmetry breaking in three-dimensional QED.
In three-dimensional QED with a Chern–Simons term we study the phase structure associated with chiral-symmetry breaking in the framework of the Schwinger–Dyson equation. We give detailed analyses on the analytical and numerical solutions for the Schwinger–Dyson equation of the fermion propagator, where the nonlocal gauge-fixing procedure is adopted to avoid wavefunction renormalization for the ...
