Low temperature limit of lattice QCD
K. Nagata, A. Nakamura, S. Motoki
We study the low temperature limit of lattice QCD by using a reduction formula for a fermion determinant. The reduction formula, which is useful in finite density lattice QCD simul…
On early onset of quark number density at zero temperature
Keitaro Nagata
We study a longstanding problem in lattice QCD at low temperature and nonzero quark chemical potential on an onset of the quark number density at . We introduce a physical…
Towards extremely dense matter on the lattice
Keitaro Nagata, Shinji Motoki, Yoshiyuki Nakagawa +2
QCD is expected to have a rich phase structure. It is empirically known to be difficult to access low temperature and nonzero chemical potential regions in lattice QCD simulati…
Development of Lattice QCD Tool Kit on Cell Broadband Engine Processor
Shinji Motok, i Yoshiyuki Nakagawa, Keitaro Nagata +3
We report an implementation of a code for SU(3) matrix multiplication on Cell/B.E., which is a part of our project, Lattice Tool Kit on Cell/B.E.. On QS20, the speed of the matrix…
EoS of finite density QCD with Wilson fermions by Multi-Parameter Reweighting and Taylor expansion
Keitaro Nagata, Atsushi Nakamura
The equation of state (EoS), quark number density and susceptibility at nonzero quark chemical potential are studied in lattice QCD simulations with a clover-improved Wilson fe…
