Functional conjugation methods are used to analyze the global structure of various renormalization group trajectories and to gain insight into the interplay between continuous and discrete rescaling. With minimal assumptions, the methods produce continuous flows from step-scaling {sigma} functions and lead to exact functional relations for the local flow {beta} functions, whose solutions may have novel, exotic features, including multiple branches. As a result, fixed points of {sigma} are… Expand
Volume Effects in Discrete beta functions
We calculate discrete beta functions corresponding to the two-lattice matching for the 2D O(N) models and Dyson's hierarchical model. We describe and explain finite-size effects such as theExpand

The Theme Issue provides articles reviewing recent progress made using the RG method in atomic, condensed matter, nuclear and particle physics, in a way that emphasizes common themes and the universal aspects of the method. Expand
RG flows, cycles, and c-theorem folklore
Monotonic renormalization group flows of the “c” and “a” functions are often cited as reasons why cyclic or chaotic coupling trajectories cannot occur. It is argued here, based on simple examples,Expand
Renormalization group flows, cycles, and c-theorem folklore.
It is argued here, based on simple examples, that simultaneous monotonic and cyclic flows can be compatible if the flow function is multivalued in the couplings. Expand
Branched Hamiltonians and supersymmetry
Some examples of branched Hamiltonians are explored both classically and in the context of quantum mechanics, as recently advocated by Shapere and Wilczek. These are in fact cases of switchbackExpand
Approximate solutions of functional equations
Approximate solutions to functional evolution equations are constructed through a combination of series and conjugation methods, and relative errors are estimated. The methods are illustrated, bothExpand
Renormalization Group and Phase Transitions in Spin, Gauge, and QCD Like Theories
In this thesis, we study several different renormalization group (RG) methods, including the conventional Wilson renormalization group, Monte Carlo renormalization group (MCRG), exact renormalizationExpand
Potentials unbounded below
Continuous interpolates are described for classical dynamical systems defined by discrete time-steps. Functional conjugation methods play a central role in obtaining the interpolations. TheExpand
Large-spin expansions of GKP strings
A bstractWe demonstrate that the large-spin expansion of the energy of Gubser-Klebanov-Polyakov (GKP) strings that rotate in ℝ × S2 and AdS3 can be expressed in terms of Lambert’s W-function. WeExpand

Renormalization group limit cycles and field theories for ellipticS-matrices
The renormalization group (RG) for maximally anisotropic su(2) current interactions in two dimensions is shown to be cyclic at one-loop level. The fermionized version of the model exhibitsExpand
Russian doll renormalization group and Kosterlitz–Thouless flows
Abstract We investigate the previously proposed cyclic regime of the Kosterlitz–Thouless renormalization group (RG) flows. The period of one cycle is computed in terms of the RG invariant. UsingExpand
Renormalization Group and Strong Interactions
The renormalization-group method of Gell-Mann and Low is applied to field theories of strong interactions. It is assumed that renormalization-group equations exist for strong interactions whichExpand
Limit cycles in quantum theories.
This work discusses the simplest quantum model Hamiltonian identified so far that exhibits a renormalization group with both limit cycle and chaotic behavior, a discrete Hermitian matrix with two coupling constants. Expand
