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…
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…
Lattice QCD and High Baryon Density State
Atsushi Nakamura, Keitaro Nagata, Shinji Motoki +2
We report our recent studies on the finite density QCD obtained from lattice QCD simulation with clover-improved Wilson fermions of two flavor and RG-improved gauge action. We appr…
Quantum entanglement in SU(3) lattice Yang-Mills theory at zero and finite temperatures
Y. Nakagawa, A. Nakamura, S. Motoki +1
We examine the entanglement properties of the Yang-Mills theory by calculating entanglement entropy with using a SU(3) quenched lattice gauge simulation both in the confi…
Wilson fermions with imaginary chemical potential
Keitaro Nagata, Atsushi Nakamura, Yoshiyuki Nakagawa +3
We study the phase structure of imaginary chemical potential. We calculate the Polyakov loop using clover-improved Wilson action and renormalization improved gauge action. We obtai…
Entanglement entropy of SU(3) Yang-Mills theory
Y. Nakagawa, A. Nakamura, S. Motoki +1
We calculate the entanglement entropy using a SU(3) quenched lattice gauge simulation. We find that the entanglement entropy scales as at small as in the conformal fiel…
