Dimensionless Quantities, Logarithmic Axes, and Thinking Like a Physicist
Two time-honored tricks allow physicists to reduce equations to their most essential elements and represent them graphically. Understanding dimensionless quantities and logarithmic axes will empower you to make sense of the universe. 1 Dimensionless Quantities For any physically significant parameter, there is always at least one physically meaningful scale. For example, an appropriate length s...
متن کاملConserved quasilocal quantities and general covariant theories in two dimensions.
General matterless–theories in 1+1 dimensions include dilaton gravity, Yang– Mills theory as well as non–Einsteinian gravity with dynamical torsion and higher power gravity, and even models of spherically symmetric d = 4 General Relativity. Their recent identification as special cases of ’Poisson–sigma–models’ with simple general solution in an arbitrary gauge, allows a comprehensive discussion...

متن کاملLogarithmic Conformal Field Theory Through Nilpotent Conformal Dimensions
We study logarithmic conformal field theories (LCFTs) through the introduction of nilpotent conformal weights. Using this device, we derive the properties of LCFT’s such as the transformation laws, singular vectors and the structure of correlation functions. We discuss the emergence of an extra energy momentum tensor, which is the logarithmic partner of the energy momentum tensor. PACS: 11.25.Hf
متن کاملSelf Avoiding Walks in Four Dimensions: Logarithmic Corrections
We present simulation results for long (N ≤ 4000) self-avoiding walks in four dimensions. We find definite indications of logarithmic corrections, but the data are poorly described by the asymptotically leading terms. Detailed comparisons are presented with renormalization group flow equations derived in direct renormalization and with results of a field theoretic calculation.
