Application of Non-Perturbative Renormalization Group to Nambu-Jona-Lasinio/Gross-Neveu model at Finite Temperature and Chemical Potential
Hiroaki Kodama, Jun-Ichi Sumi
The chiral phase structure of the Nambu-Jona-Lasinio/Gross-Neveu model at finite temperature T and finite chemical potential μis investigated using (Wilsonian) Non-Perturbative Ren…
Time of arrival through interacting environments: Tunneling processes
Ken-Ichi Aoki, Atsushi Horikoshi, Etsuko Nakamura
We discuss the propagation of wave packets through interacting environments. Such environments generally modify the dispersion relation or shape of the wave function. To study such…
Kaluza-Klein Thresholds and Regularization (In)dependence
Jisuke Kubo, Haruhiko Terao, George Zoupanos
We present a method to control the regularization scheme dependence in the running of couplings in Kaluza-Klein theories. Specifically we consider the scalar theory in five dimensi…
A New Gauge Fixing Method for Abelian Projection
F. Shoji, T. Suzuki, H. Kodama +1
We formulate a stochastic gauge fixing method to study the gauge dependence of the Abelian projection. We consider a gauge which interpolates between the maximal Abelian gauge and…
Gauge invariant field strength correlators from RG smoothing and color correlations between topological charge clusters
E. -M. Ilgenfritz, S. Thurner
Using the renormalization group based smoothing technique we have studied the gauge invariant field strength correlator at T\ne0 and T=0 in pure SU(2) gauge theory. In conjunction…
Recent topics of infrared effective lattice QCD
K. Yamagishi, S. Kitahara, S. Ito +7
Three topics concerning infrared effective lattice QCD are discussed. (1)Perfect lattice action of infrared SU(3) QCD and perfect operators for the static potential are analyticall…
