Studying the QCD Matter produced in Heavy-Ion Collisions using the MUSES Calculation Engine
Johannes Jahan, Kevin P. Pala, Yumu Yang +42
The equation of state of hot and dense matter is essential for describing heavy-ion collisions at all collision energies. Here, we explore the capabilities of the latest version of…
Meson molecules in strong magnetic fields: non-monotonic evolution of the charged pion and kaon energies
Toru Kojo
In strong magnetic fields, charged quarks occupy the lowest Landau level, leading to an effective dimensional reduction of hadronic dynamics. This dimensional reduction naturally g…
A quarkyonic matter model
Toru Kojo
Quarkyonic matter is a state of matter in dense QCD whose bulk thermodynamics is dominated by quarks, while low-energy excitations remain confined. This picture leads to a crossove…
Delineating neutral and charged mesons in magnetic fields
Toru Kojo, Sakura Itatani
We investigate the properties of neutral and charged mesons in magnetic fields, from weak-field to strong-field regimes. To develop analytic insights, we employ a non-relativistic…
Quarkyonic matter and hadron-quark crossover from an ultracold atom perspective
Hiroyuki Tajima, Kei Iida, Toru Kojo +1
The dense matter equation of state is of great interest due to the recent development of astrophysical observations for neutron stars. A rapid increase in pressure indicates a cont…
QCD-Like Theories with Different Color Numbers
Toru Kojo
Quantum chromodynamics (QCD) with a general number of colors, $\Nc$, provides a powerful theoretical laboratory to explore the dynamics of non-Abelian gauge theories. Although $\Nc…
Stiffening of matter in quark-hadron continuity: a mini-review
Toru Kojo
Recent observations of neutron stars, combined with causality, thermodynamic stability, and nuclear constraints, indicate a rapid stiffening of QCD matter at densities slightly abo…
Evolution of strangeness and hyperons in quarkyonic matter
Yuki Fujimoto, Toru Kojo, Larry McLerran
We study the evolution of matter composition from nuclear to quark densities in the confining regime, by extending an ideal model of Quarkyonic matter, IdylliQ model, to multi-flav…
Neutron-quark stars: Discerning viable alternatives for the higher-density part of the equation of state of compact stars
Sudipta Hensh, Yong-Jia Huang, Toru Kojo +4
We investigate binary neutron star (BNS) mergers using general-relativistic numerical simulations with hadronic and hybrid equations of state (EOSs), incorporating the latest obser…
