Dense Nuclear Matter Equation of State from Heavy-Ion Collisions
Agnieszka Sorensen, Kshitij Agarwal, Kyle W. Brown +133
The nuclear equation of state (EOS) is at the center of numerous theoretical and experimental efforts in nuclear physics. With advances in microscopic theories for nuclear interact…
Trace anomaly as signature of conformality in neutron stars
Yuki Fujimoto, Kenji Fukushima, Larry D. McLerran +1
We discuss an interpretation that a peak in the sound velocity in neutron star matter, as suggested by the observational data, signifies strongly-coupled conformal matter. The norm…
Gravitational Wave Signal for Quark Matter with Realistic Phase Transition
Yuki Fujimoto, Kenji Fukushima, Kenta Hotokezaka +1
The cores of neutron stars (NSs) near the maximum mass realize the most highly compressed matter in the universe where quark degrees of freedom may be liberated. Such a state of de…
Equation of state of neutron star matter and its warm extension with an interacting hadron resonance gas
Yuki Fujimoto, Kenji Fukushima, Yoshimasa Hidaka +2
We propose an interpolating equation of state that satisfies phenomenologically established boundary conditions in two extreme regimes at high temperature and low baryon density an…
Topological confinement of vortices in two-flavor dense QCD
Yuki Fujimoto, Muneto Nitta
We find a novel confinement mechanism in the two-flavor dense quark matter proposed recently, that consists of the 2SC condensates and the -wave diquark condensates of -quark…
Alice meets Boojums in neutron stars: vortices penetrating two-flavor quark-hadron continuity
Yuki Fujimoto, Muneto Nitta
Alice and Boojums are both representative characters created by Lewis Carroll. We show that they possibly meet in cores of rotating neutron stars. Recent studies of quark-hadron co…
Deconfining Phase Boundary of Rapidly Rotating Hot and Dense Matter and Analysis of Moment of Inertia
Yuki Fujimoto, Kenji Fukushima, Yoshimasa Hidaka
We discuss the effect of rapid rotation on the phase diagram of hadronic matter. The energy dispersion relation is shifted by an effective chemical potential induced by rotation. T…
Extensive Studies of the Neutron Star Equation of State from the Deep Learning Inference with the Observational Data Augmentation
Yuki Fujimoto, Kenji Fukushima, Koichi Murase
We discuss deep learning inference for the neutron star equation of state (EoS) using the real observational data of the mass and the radius. We make a quantitative comparison betw…
Equation of state of cold and dense QCD matter in resummed perturbation theory
Yuki Fujimoto, Kenji Fukushima
We discuss the Hard Dense Loop resummation at finite quark mass and evaluate the equation of state (EoS) of cold and dense QCD matter in equilibrium. The resummation in the qua…
Non-Abelian Alice strings in two-flavor dense QCD
Yuki Fujimoto, Muneto Nitta
Quark-hadron continuity with two-flavor quarks that was proposed recently connects hadronic matter with neutron superfluidity and two-flavor dense quark matter. This two-fl…
Continuity from neutron matter to color-superconducting quark matter with superfluidity
Yuki Fujimoto
I clarify how the concept of quark-hadron continuity, which was previously considered in the context of the asymptotic color-flavor locked phase with ideal three-flavor symmetry, i…
Continuity from neutron matter to two-flavor quark matter with and superfluidity
Yuki Fujimoto, Kenji Fukushima, Wolfram Weise
This study is performed with the aim of gaining insights into the possible applicability of the quark-hadron continuity concept, not only in the idealized case of three-flavor symm…
Mapping neutron star data to the equation of state using the deep neural network
Yuki Fujimoto, Kenji Fukushima, Koichi Murase
The densest state of matter in the universe is uniquely realized inside central cores of the neutron star. While first-principles evaluation of the equation of state of such matter…
Methodology study of machine learning for the neutron star equation of state
Yuki Fujimoto, Kenji Fukushima, Koichi Murase
We discuss a methodology of machine learning to deduce the neutron star equation of state from a set of mass-radius observational data. We propose an efficient procedure to deal wi…
Deformation of the Fermi Surface and Anomalous Mass Renormalization by Critical Spin Fluctuations through Asymmetric Spin-Orbit Interaction
Yukinobu Fujimoto, Kazumasa Miyake, Hiroyasu Matsuura
It is shown that an asymmetric spin-orbit interaction is appreciably renormalized by the effect of critical spin fluctuations. As an explicit example, the Rashba-type interaction i…
