Mobility edge and locality of the overlap-Dirac operator with and without dynamical overlap fermions
JLQCD Collaboration, N. Yamada, S. Aoki +8
We perform a systematic study of low-lying eigenmodes of with various gauge actions to find the optimal choice for dynamical overlap fermion simulations, with which one may a…
JLQCD's dynamical overlap project
JLQCD Collaboration, T. Kaneko, S. Aoki +11
We present an overview of our project of large-scale simulations with dynamical overlap fermions. The first production run in two-flavor QCD is on-going using the Iwasaki gauge act…
Exploration of sea quark effects in two-flavor QCD with the O(a)-improved Wilson quark action
JLQCD Collaboration, S. Aoki, R. Burkhalter +15
We explore sea quark effects in the light hadron mass spectrum in a simulation of two-flavor QCD using the nonperturbatively O(a)-improved Wilson fermion action. In order to identi…
Non-trivial phase structure of QCD with -improved Wilson fermion at zero temperature
JLQCD Collaboration, S. Aoki, R. Burkhalter +15
JLQCD collaboration recently started the QCD simulations with the -improved Wilson fermion action employing an exact fermion algorithm developed for odd number of qua…
