Effective action from the functional renormalization group
We study the quantum gravitational system coupled to a charged scalar, Dirac fermions, and electromagnetic fields. We use the "exact" or "functional" renormalization group equation to derive the effective action Gamma(0) by...

Large logarithms from quantum gravitational corrections to a massless, minimally coupled scalar on de Sitter
using the renormalization group with one of the higher derivative counterterms regarded as a curvature-dependent field strength renormalization. We discuss how these results set the stage for a project to purge gauge depen...

Finite-temperature behavior of the .nu.=1 quantum Hall effect in bilayer electron system.
An effective field theoretic description of nu=1 bilayer electron systems stabilized by Coulomb repulsion in a single wide quantum well is examined using renormalization-group techniques....

Renormalization effects on the MSSM from a calculable model of a strongly coupled hidden sector
the hidden sector to the MSSM renormalization group flows is computed. For concretenessWe investigate possible renormalization effects on the low-energy mass spectrum coupled hidden sector. We model the hidden sector by N=...

Massively parallel quantum chemical density matrix renormalization group method
We present, to the best of our knowledge, the first attempt to exploit the super-computer platform for quantum chemical density matrix renormalization group (QC-DMRG) calculations. We have developed the parallel scheme base...

Renormalization effects on MSSM from a calculable model of strongly coupled hidden sector
quantum chromodynamics with gauge group $SU(2)times U(1)$ and $N_f=2$ matter is renormalized, contributing to the MSSM renormalization group flows via gauge mediation. In contrast to perturbative examples...

Quasinormal modes of renormalization group improved Dymnikova regular black holes
We find accurate quasinormal frequencies of a quantum corrected black hole constructed in the renormalization group theory via the coordinate-independent iterative procedure, leading to the Dymnikova regular black hole. We ...

Renormalization group equations and matching in a general quantum field theory with kinetic mixing
We work out a set of simple rules for adopting the two-loop renormalization group equations of a generic gauge field theory given in the seminal works of Machacek and Vaughn to the most general case with an arbitrary number of Abeli...
