Open AccessTheoretical and experimental constraints for the equation of state of dense and hot matter
This review aims at providing an extensive discussion of modern constraints relevant for dense and hot strongly interacting matter. It includes theoretical first-principle results from lattice and perturbative...

Open AccessProjecting XRP price burst by correlation tensor spectra of transaction networks
Cryptoassets are becoming essential in the digital economy era. XRP is one of the large market cap cryptoassets. Here, we develop a novel method of correlation tensor spectra for the dynamical XRP networks, wh...

Open AccessHybrid quantum annealing via molecular dynamics
A novel quantum–classical hybrid scheme is proposed to efficiently solve large-scale combinatorial optimization problems. The key concept is to introduce a Hamiltonian dynamics of the classical flux variables ...

Baryon–baryon interactions at short distances: constituent quark model meets lattice QCD
The interaction energies between two baryons at short distance in different flavor channels are calculated from the constituent quark model (CQM) and are compared with the recent lattice QCD (LQCD) results for...

Open AccessSuperfluid Phase Transitions and Effects of Thermal Pairing Fluctuations in Asymmetric Nuclear Matter
We investigate superfluid phase transitions of asymmetric nuclear matter at finite temperature (T) and density (ρ) with a low proton fraction (Yp ≤ 0.2), which is relevant to the inner crust and outer core of neu...

Open AccessConsistency between Lüscher’s finite volume method and HAL QCD method for two-baryon systems in lattice QCD
There exist two methods to study two-baryon systems in lattice QCD: the direct method which extracts eigenenergies from the plateaux of the temporal correlation function and the HAL QCD method which extracts o...

Lattice quantum chromodynamics and baryon-baryon interactions
After briefly reviewing the theoretical concepts and numerical methods in lattice QCD, recent simulation results of the hadron masses and hadron interactions with nearly physical quark masses are presented. Sp...

Lattice Quantum Chromodynamics
Concepts and applications of lattice quantum chromodynamics (LQCD) are introduced. After discussing how to define quarks and gluons on the Euclidean hypercubic lattice, the strong coupling expansion and the we...

Hyperon puzzle, hadron-quark crossover and massive neutron stars
Bulk properties of cold and hot neutron stars are studied on the basis of the hadron-quark crossover picture where a smooth transition from the hadronic phase to the quark phase takes place at finite baryon de...

Numerical study of QCD phase diagram at high temperature and density by a histogram method
We study the QCD phase structure at high temperature and density adopting a histogram method. Because the quark determinant is complex at finite density, the Monte-Carlo method cannot be applied directly. We u...

In-medium spectral functions from lattice QCD
Hadronic modes in the quark-gluon plasma and their spectral properties are discussed on the basis of the lattice QCD data analyzed by the maximum entropy method.

Wandering in color-space why is the life of pentaquark so long?
The problem of the long life time of the pentaquark Θ+ is investigated on the basis of the color molecular dynamics simulation. We find that it takes a long time (typically of 50–100 fm/c) for the initial pentaqu...

Collective dynamics for the bag: Semiclassical approach to the breathing motion
Starting from the bag Lagrangian, we derive a collective Lagrangian which describes the breathing motion of the bag in a microscopic manner. The essential point of our procedure is to adopt a parametrized quar...
