Phase structure and critical phenomena in 2-flavor QCD by holography
arXiv (Cornell University)(2023)
摘要
We explore the phase structure of Quantum Chromodynamics (QCD) with two
dynamical quark flavors at finite temperature and baryon chemical potential,
employing the non-perturbative gauge/gravity duality approach. Our
gravitational model is tailored to align with state-of-the-art lattice data
regarding the thermal properties of multi-flavor QCD. Following a rigorous
parameter calibration to match equations of state and the QCD trace anomaly at
zero chemical potential derived from cutting-edge lattice QCD simulations, we
investigate thermodynamic quantities and order parameters. We predict the
location of the critical endpoint (CEP) at (μ_CEP,
T_CEP)=(219,182) MeV at which a line of first-order phase transitions
terminate. We compute critical exponents associated with the CEP and find that
they almost coincide with the critical exponents of the quantum 3D Ising model.
