Vacua, Connnement and the Continuum Limit

چکیده

We investigate the dependence of the CP 3 model and of the SU(2) Yang-Mills theory on the vacuum angle. The CP 3 model exhibits a rst order deconnning phase transition in. The critical value of runs from in the strong coupling limit towards zero as is taken to innnity. Qualitatively the same behavior is found in the SU(2) Yang-Mills theory in four dimensions. We discuss the renormalization group trajectories. Only the line with = 0 allows the cut-oo to go to innnity, while the lines with > 0 end on the line of rst order phase transitions. Thus is forced to zero in the continuum limit.

A Note on Dual Superconductivity and Connnement

Electric self-dual vortices arising as BPS states in the strong coupling limit of N=2 supersymmetric Yang-Mills theory, softly broken to N = 1, are reported. 1. About twenty years ago, 't Hooft and Mandelstam 1], 2] proposed a qualitative description of the quark connnement phenomenon based on an analogy with superconductivity. According to this interpretation, the QCD vacuum behaves as a \dual...

Discretuum versus Continuum Dark Energy

The dark energy equation of state for theories with either a discretuum or continuum distribution of vacua is investigated. In the discretuum case the equation of state is constant w = p/ρ = −1. The continuum case may be realized by an action with large wave function factor Z for the dark energy modulus and generic potential. This form of the action is quantum mechanically stable and does not l...

Disorder on the landscape

Disorder on the string theory landscape may significantly affect dynamics of eternal inflation leading to the possibility for some vacua on the landscape to become dynamically preferable over others. We systematically study effects of a generic disorder on the landscape starting by identifying a sector with builtin disorder – a set of de Sitter vacua corresponding to compactifications of the Ty...

Battiti and Tecchiolli : Training Neural Nets with the Reactive Tabu

| In this paper the task of training sub-symbolic systems is considered as a combinatorial optimization problem and solved with the heuristic scheme of the Reactive Tabu Search. An iterative optimization process based on a \modiied greedy search" component is complemented with a meta-strategy to realize a discrete dynamical system that discourages limit cycles and the connnement of the search t...

Boundary Eeects and Connnement in the Gauge Eld Theory

The connnement criterion based on the dependence of the partition function on the boundary condition for the electric eld strength is presented for the non{abelian gauge theory. It is supported by an approximate calculation of the partition function and the Wilson loop for SU(N) gluodynamics in the 3-d Fock{Schwinger gauge. Possible directions of further studies of connnement are outlined.
