Alternative Dimensional Reduction via the Density Matrix
We give graphical rules, based on earlier work for the functional Schrödinger equation, for constructing the density matrix for scalar and gauge fields in equilibrium at finite temperature T . More useful is a dimensionally-reduced effective action (DREA) constructed from the density matrix by further functional integration over the arguments of the density matrix coupled to a source. The DREA ...
متن کاملAlternative dimensional reduction via the density matrix: A test
We derive and analyze the perturbation series for the classical effective potential in quantum statistical mechanics, treated as a toy model for the dimensionally reduced effective action in quantum field theory at finite temperature. The first few terms of the series are computed for the harmonic oscillator and the quartic potential.
متن کاملAn Alternative Dimensional Reduction Prescription
We propose an alternative dimensional reduction prescription which in respect with Green functions corresponds to drop the extra spatial coordinate. From this, we construct the dimensionally reduced Lagrangians both for scalars and fermions, discussing bosonization and supersymmetry in the particular 2-dimensional case. We argue that our proposal is in some situations more physical in the sense...
متن کاملDimensional reduction via dimensional shadowing
1. Uni ed eld theories suggest a N dimensional conguration space with N̄ = N−4 > 0 extra dimensions not perceived in nature. The common heuristic reasons for this proposition are: (i) the volume [Hausdor measure] does not scale like μH(δ,R ) = δ μH(1,R ), where δ is some length scale and 1 stands for its unity. Instead, experience tells us that increasing (or decreasing) the spacial size of an o...
متن کاملHomology Annotations via Matrix Reduction
In this work, we propose an alternative algorithm for annotating simplices of a simplicial complex K with sub-bases of a basis B of its p-dimensional homology group H1(K). Such annotations, summed over p-simplices in any p-cycle z, provide an expression of z in B. This allows us to answer queries of null homology and independence of p-cycles efficiently and improve the running time of the greed...
