Large N QCD – Continuum Reduction and Chiral Condensate
Continuum reduction in large N QCD enables one to extract physical quantities in the N → ∞ limit of QCD by working in small physics volumes. The computation of chiral condensate is an example of such a calculation.
متن کاملA large N phase transition in the continuum two dimensional SU ( N ) X SU ( N ) principal chiral model
It is established by numerical means that the continuum large N principal chiral model in two dimensions has a phase transition in a smoothed two point function at a critical distance of the order of the correlation length.
متن کاملChiral anomalies in the reduced model
On the basis of an observation due to Kiskis, Narayanan and Neuberger, we show that there is a remnant of chiral anomalies in the reduced model when a Dirac operator which obeys the Ginsparg-Wilson relation is employed for the fermion sector. We consider fermions belonging to the fundamental representation of the gauge group U(N) or SU(N). For vector-like theories, we determine a general form o...
متن کاملContinuum model for chiral induced spin selectivity in helical molecules.
A minimal model is exactly solved for electron spin transport on a helix. Electron transport is assumed to be supported by well oriented p(z) type orbitals on base molecules forming a staircase of definite chirality. In a tight binding interpretation, the spin-orbit coupling (SOC) opens up an effective π(z) - π(z) coupling via interbase p(x,y) - p(z) hopping, introducing spin coupled transport....
متن کاملRealizing chiral fermions in the type IIB matrix model at finite N
We discuss how chiral fermions can appear in the type IIB matrix model, which is considered to be a nonperturbative formulation of superstring theory. In particular, we are concerned with a constructive definition of the theory, in which we start with a finiteN configuration and take the large-N limit later on. We point out that there exists a certain necessary condition which the structure of ...
