Sign problem and the chiral spiral on the finite-density lattice
Ryutaro Fukuda, Kenji Fukushima, Tomoya Hayata +1
We investigate the sign problem of the fermion determinant at finite baryon density in (1+1) dimensions, in which the ground state in the chiral limit should be free from the sign…
Turbulent pattern formation and diffusion in the early-time dynamics in the relativistic heavy-ion collision
Kenji Fukushima
We propose a picture of turbulent pattern formation in the relativistic heavy-ion collision, which follows an efficient process to break color strings and dispose energy in the who…
Spatial modulation and topological current in holographic QCD matter
Kenji Fukushima, Pablo Morales
We investigate an impact of the axial-vector interaction on spatial modulation of quark matter. A magnetic field coupled with baryon density leads to a topological axial current, s…
Stabilizing perturbative Yang-Mills thermodynamics with Gribov quantization
Kenji Fukushima, Nan Su
We evaluate the thermodynamic quantities of Yang-Mills theory using the Gribov quantization, which deals with nonperturbative resummation. The magnetic scale is automatically incor…
The phase diagram of nuclear and quark matter at high baryon density
Kenji Fukushima, Chihiro Sasaki
We review theoretical approaches to explore the phase diagram of nuclear and quark matter at high baryon density. We first look over the basic properties of quantum chromodynamics…
