Equation of state of QCD(-like) theory using Lattice Monte Carlo simulations
Etsuko Itou
The equation of state (EoS) of strongly interacting matter at low temperature and high baryon density is a central ingredient in the physics of compact stars, but it is still diffi…
Hadron spectra of finite-density QCD
Kei Iida, Etsuko Itou, Kotaro Murakami +1
We investigate the chemical-potential dependence of hadron spectra in two-color QCD using first-principles lattice simulations. We compute two-point correlation functions for all a…
Speed of sound exceeding the conformal bound in dense QCD-like theories
Etsuko Itou, Kei Iida, Kotaro Murakami +1
We investigated the phase structure and the equation of state (EoS) for dense two-color QCD at low temperatures using the lattice Monte Carlo simulations. A rich phase structure be…
Lattice results for the equation of state in dense QCD-like theories
Etsuko Itou
We review recent progress in Monte Carlo simulations of dense two-color QCD (QCD), focusing on the phase diagram, the equation of state, and the sound velocity in the low-tempe…
New computational methods in lattice gauge theory -- quantum computation and tensor networks
Etsuko Itou
Lattice QCD calculations have been conducted using large-scale classical computers based on the Lagrangian formalism of field theory for the past 40 years. On the other hand, the a…
Phase and equation of state of finite density QCD at lower temperature
Etsuko Itou, Kei Iida, Kotaro Murakami +1
We investigate the phase structure and the equation of state (EoS) for dense two-color QCD at low temperatures, MeV ( lattice) and MeV ( lattice). A r…
Scale setting and hadronic properties in light quark sector with -flavor Wilson fermions at the physical point
Tatsumi Aoyama, Takahiro M. Doi, Takumi Doi +4
We report scale setting and hadronic properties for our new lattice QCD gauge configuration set (HAL-conf-2023). We employ -flavor nonperturbatively improved Wilson fermions…
Lattice study on finite density QCD towards zero temperature
Kei Iida, Etsuko Itou, Kotaro Murakami +1
We investigate the phase structure and the equation of state (EoS) for dense two-color QCD (QCD) at low temperature ( MeV, lattice) for the purpose of extending…
Mass spectrum of spin-one hadrons in dense two-color QCD: Novel predictions by extended linear sigma model
Daiki Suenaga, Kotaro Murakami, Etsuko Itou +1
We construct an extended version of the linear sigma model in such a way as to describe spin- hadrons as well as spin- hadrons in two-color QCD (QCD) by respecting the Pa…
Speed of sound exceeding the conformal bound in dense 2-color QCD
Etsuko Itou, Kei Iida
We review recent works on the Monte Carlo simulations of dense two-color QCD (QCD) by focusing on the phase diagram, the equation of state, and the sound velocity at nonzero qu…
Chemical potential (in)dependence of hadron scatterings in the hadronic phase of QCD-like theories and its applications
Kotaro Murakami, Etsuko Itou, Kei Iida
We formulate a method for calculating the hadron-hadron scattering amplitudes at nonzero chemical potential () in the hadronic phase at zero temperature, where the baryon number…
Unitarity Bound of the Wave Function Renormalization Constant
K. Higashijima, E. Itou
The wave function renormalization constant , the probability to find the bare particle in the physical particle, usually satisfies the unitarity bound in field…
