F-method for symmetry breaking operators

Fluctuation Operators and Spontaneous Symmetry Breaking

In the following we develop an in various respects new approach to this field, which was to a large extent developed by Verbeure et al. and which may complement their approach, which is largely based on a noncommutative central limit theorem. In contrast to that we deal directly with the limits of l-point truncated correlation functions and show that they typically vanish for l ≥ 3 provided tha...

New Method for Dynamical Fermions and Chiral-Symmetry Breaking

where the fermionic degrees of freedom have been integrated out, and N f is number of flavors taking into account the species doubling. Spl is the plaquette energy [Spl = ∑ pRe(Up)/Nc, for a compact theory, and Spl = − ∑ p θ 2 p/2, for noncompact QED]. The fermionic determinant det∆(m,U) accounts for the effects of dynamical fermions; its numerical evaluation requires in general a huge CPU time...

THE FRANK KINETIC MODEL FOR SPONTANEOUS CHIRAL SYMMETRY BREAKING WITH VARIABLE CONCENTRATION OF THE ACHIRAL SUBSTRATE

This paper considers the possibility of spontaneous transition of aracemic mixture (composed of equal amounts of two enantiomeric species, say L and D) into a monochiral state (in which only one enantiomer, say L, is present). Transitions of this kind have been recently experimentally observed. A plausible approach to this phenomenon is a model put forward by Frank, based on simple laws of ...

Symmetry Breaking

Symmetry occurs in many problems in aritifical intelligence. For example, in the n-queens problem, the chessboard can be rotated 90◦. As a second example, several machines in a factory might have the same capacity. In a production schedule, we might therefore be able to swap the jobs on machines with the same capacity. As a third example, two people within a company might have the same skills. ...
