Monte Carlo and renormalization-group effective potentials in scalar field theories.
We study constraint effective potentials for various strongly interacting φ theories. Renormalization group (RG) equations for these quantities are discussed and a heuristic development of a commonly used RG approximation is presented which stresses the relationships among the loop expansion, the Schwinger-Dyson method and the renormalization group approach. We extend the standard RG treatment ...
متن کاملMultiscale renormalization group improvement of the effective potential.
Using the renormalisation group and a conjecture concerning the perturbation series for the effective potential, the leading logarithms in the effective potential are exactly summed for O(N) scalar and Yukawa theories.
متن کاملGeneral Solutions for Tunneling of Scalar Fields with Quartic Potentials
For the theory of a single scalar field φ with a quartic potential V (φ), we find semianalytic expressions for the Euclidean action in both four and three dimensions. The action in four dimensions determines the quantum tunneling rate at zero temperature from a false vacuum state to the true vacuum state; similarly, the action in three dimensions determines the thermal tunneling rate for a fini...
متن کاملRenormalization Group Analysis of Scalar Field
We employ Wilson's renormalization group procedure in an attempt to classify and understand the physics of the continuum limits of scalar field theories. Analysis of the flows near the Gaussian fixed point reveals the existence of an infinite set of asymptotically free continuum limits. We study the associated physics by calculating scattering cross sections and the i-loop effective potential. ...
متن کاملRenormalization group domains of the scalar Hamiltonian . ∗
Using the local potential approximation of the exact renormalization group (RG) equation , we show the various domains of values of the parameters of the O(1)-symmetric scalar hamiltonian. In three dimensions, in addition to the usual critical surface S c (attraction domain of the Wilson-Fisher fixed point), we explicitly show the existence of a first-order phase transition domain S f separated...
