Dynamical evolution of critical fluctuations with second-order baryon diffusion coupled to chiral condensate
Azumi Sakai, Koichi Murase, Hirotsugu Fujii +1
We develop a dynamical model to describe critical fluctuations in heavy-ion collisions, incorporating the baryon diffusion current and chiral condensate as dynamical degrees of fre…
Repulsive potentials in dense neutron star matter and binding energy of in hypernuclei
Asanosuke Jinno, Koichi Murase, Yasushi Nara +1
The repulsive three-body force between the lambda () hyperon and medium nucleons is a key element in solving the hyperon puzzle in neutron stars. We investigate the binding ener…
Efficient solver of relativistic hydrodynamics with implicit Runge-Kutta method
Nathan Touroux, Masakiyo Kitazawa, Koichi Murase +1
We propose a new method to solve the relativistic hydrodynamic equations based on implicit Runge-Kutta methods with a locally optimized fixed-point iterative solver. For numerical…
A Poincaré covariant cascade method for high-energy nuclear collisions
Yasushi Nara, Asanosuke Jinno, Tomoyuki Maruyama +2
We present a Poincaré covariant cascade algorithm based on the constrained Hamiltonian dynamics in an -dimensional phase space to simulate the Boltzmann-type two-body collision…
Hydrodynamic fluctuations and ultra-central flow puzzle in heavy-ion collisions
Kenshi Kuroki, Azumi Sakai, Koichi Murase +1
One of the long-standing problems in the field of high-energy heavy-ion collisions is that the dynamical models based on viscous hydrodynamics fail to describe the experimental ell…
Directed flow of from heavy-ion collisions and hyperon puzzle of neutron stars
Akira Ohnishi, Asanosuke Jinno, Koichi Murase +1
We examine the potential from the chiral effective field theory (EFT) via the directed flow from heavy-ion collisions. We implement the potential obtained from the $…
