The Global Renormalization Group Trajectory in a Critical Supersymmetric Field Theory on the Lattice Z
We consider an Euclidean supersymmetric field theory in Z given by a supersymmetric Φ perturbation of an underlying massless Gaussian measure on scalar bosonic and Grassmann fields with covariance the Green’s function of a (stable) Lévy random walk in Z. The Green’s function depends on the Lévy-Khintchine parameter α = 3+ε 2 with 0 < α < 2. For α = 3 2 the Φ 4 interaction is marginal. We prove ...
متن کاملTime-Dependent Real-Space Renormalization Group Method
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...
متن کاملQuantum lattice KdV equation
A quantum theory is developed for a difference-difference system which can serve as a toy-model of the quantum Korteveg-de-Vries equation. Introduction This Letter presents an example of a completely integrable ‘discrete-space-time quantum model’ whose Heisenberg equations of motion have the form φ (τ, n) φ (τ, n− 1) + λ φ (τ, n− 1) φ (τ − 1, n− 1) = λ φ (τ, n) φ (τ − 1, n) + φ (τ − 1, n) φ (τ ...
متن کاملClassical Non-abelian Solitons
In two space-time dimensions a class of classical multicomponent scalar field theories with discrete, in general non-Abelian global symmetry is considered. The corresponding soliton solutions are given for the cases of 2, 3, and 4 components. E–mail: [email protected] Recently renewed interest in solitons has arisen in connection with exceptional statistics occuring in low-dimensional quantu...
متن کاملA Renormalization Group Study of the ( φ ∗ φ ) 3 Model coupled to a Chern - Simons Field ∗
We consider the model of a massless charged scalar field, in (2 + 1) dimensions, with a self interaction of the form λ(φ∗φ)3 and interacting with a Chern Simons field. We calculate the renormalization group β functions of the coupling constants and the anomalous dimensions γ of the basic fields. We show that the interaction with the Chern Simons field implies in a βλ which suggests that a dynam...
