The Renormalization of the Energy-momentum Tensor for an Effective Initial State
The new physics quantum state their differences
2014/12/20
An effective description of an initial state is a method for representing the signatures of new physics in the short-distance structure of a quantum state. The expectation value of the energy-momentum...
FlowPy - a numerical solver for functional renormalization group equations
FlowPy numerical solver functional renormalization group equations
2012/2/29
FlowPy is a numerical toolbox for the solution of partial differential equations encountered in Functional Renormalization Group equations. This toolbox compiles flow equations to fast machine code an...
Exact density functional theory with the density matrix renormalization group
density functional theory density matrix renormalization group electronic structure models
2011/8/17
Abstract: Combining density functional theory with controlled numerical methods for strongly correlated systems could greatly extend the range of both. We use the density matrix renormalization group ...
Existence of a Lorenz renormalization fixed point of an arbitrary critical order
Lorenz renormalization fixed point arbitrary critical order Dynamical Systems
2011/9/19
Abstract: We present a proof of the existence of a renormalization fixed point for Lorenz maps of the simplest non-unimodal combinatorial type ({0,1},{1,0,0}), and with a critical point of arbitrary o...
Regard Renormalization in QED as Functor between Categories
Regard Renormalization QED Functor between Categories Mathematical Physics
2011/9/19
Abstract: To unify the quantum electrodynamics (QED) under the first principle which brings the renormalization unartificially, we study Feynman diagrams in QED according to the set theory and the cat...

The choice of generator in the Similarity Renormalization Group (SRG) flow equation determines the evolution pattern of the Hamiltonian.
Series expansions from the corner transfer matrix renormalization group method: the hard squares model
Corner transfer matrix hard squares model series expansions
2011/9/30
Abstract: The corner transfer matrix renormalization group method is an efficient method for evaluating physical quantities in statistical mechanical models. It originates from Baxter's corner transfe...
A new perspective on renormalization: invariant actions, a dynamical DNA
A new perspective a dynamical DNA
2011/9/5
This is a note to a quantum field theorist, interpreting the “Mallat” transformation (i.e., group invariant scattering) [1]. First the characteristics of the transformation are examined, and related t...
The renormalization of general gauge theories on flat and curved space-time backgrounds is considered within the Sp(2)-covariant quantization method. We assume the existence of a gauge-invariant and d...
Connection between the renormalization groups of Stückelberg-Petermann and Wilson
Connection renormalization groups Stückelberg-Petermann Wilson
2011/3/4
The St¨uckelberg-Petermann renormalization group is the group of finite renormalizations of the S-matrix in the framework of causal perturbation theory.
Renormalization effects on MSSM from a calculable model of strongly coupled hidden sector
MSSM calculable model
2010/12/27
We investigate renormalization effects on the low energy mass spectrum of the minimal supersymmetric standard model (MSSM), using a calculable model of strongly coupled hidden sector. We model the hid...
Supersymmetry non-renormalization theorem from a computer and the AdS/CFT correspondence
Supersymmetry non-renormalization theorem the AdS/CFT correspondence
2010/12/27
We perform Monte Carlo calculation of correlation functions in 4d N=4 super Yang-Mills theory on R*S^3 in the planar limit. In order to circumvent the well-known problem of lattice SUSY, we adopt the ...

Heavy-light decays such as $B \to \pi \ell \nu$, $B \to K^{*} \gamma$ and $B \to K^{(*)} \ell \ell$ can be used to constrain the parameters of the Standard Model and in indirect searches for new physi...

Perturbative renormalization factors and O(a^2) corrections for lattice 4-fermion operators with improved fermion/gluon actions
Perturbative renormalization factors O(a^2) corrections
2011/1/7
In this work we calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. One of the novel aspects of our calculations is that they ar...
