VI.F Summing over Phantom Loops

چکیده
The high temperature series can be approximately summed so as to reproduce the Gaussian model. This correspondence provides a better understanding of why Gaussian behavior is applicable in high dimensions, and also prepares the way for the exact summation of the series in two dimensions in the next section. The high temperature series for the partition function of the Ising model on a d–dimensional hypercubic lattice is obtained from Z = ∑

The Lie bialgebra of loops on surfaces of Goldman and Turaev
The coproduct is given by summing over self-intersections and removing the intersection point, and smoothing to obtain two paths. Precisely, let ∩α denote the set of self-intersections of α (assuming α is in general position). The coproduct is then given by summing over selfintersections and removing the intersection point, and smoothing to obtain two paths. Then δ(〈α〉) = ∑ q∈∩α 〈α1 q〉 ∧ 〈α2 q〉...
متن کاملSumming loops in QCD: Exclusive Higgs production and the survival probability
The Pomeron loop amplitude and the amplitude for the diagram with any general number of loops is derived in the QCD dipole approach. This provides the necessary tools for solving the long standing theoretical problem of summing over Pomeron loop diagrams. In this theoretical framework the contribution of the full set of enhanced diagrams to the survival probability is estimated. This enables an...
متن کاملUnder - Knotted and over - Knotted Polymers : 1 . Unrestricted Loops
We present computer simulations to examine probability distributions of gyration radius for the no-thickness closed polymers of N straight segments of equal length. We are particularly interested in the conditional distributions when the topology of the loop is quenched to be a certain knot K. The dependence of probability distribution on length, N , as well as topological state K are the prima...

متن کاملPhysiological correlates of the precedence effect and summing localization in the inferior colliculus of the cat.
The precedence effect (PE) describes an illusion produced when two similar sounds are delivered in quick succession (interclick delays of 2-8 msec) from sound sources at different locations so that only a single sound is perceived. The localization of the perceived sound is dominated by the location of the leading sound. If the delays are very short (< 1-2 msec), summing localization occurs and...
