Description
Recently, we have conducted a series of studies on the non-perturbative dynamics of QCD matter under extreme conditions using a unified lattice-calibrated holographic framework. First, addressing the rotational response of pure gluonic matter, we established a rotation-magnetic correspondence and revealed a chromomagnetic-induced inertia inversion mechanism. We show that melting chromomagnetic flux tubes near the deconfinement temperature drive a negative Barnett effect and negative moment of inertia, an anomaly that vanishes at a critical velocity squared of approximately 0.1. Second, for finite-density systems, we constructed a thermodynamically self-consistent multi-charge model to resolve the ambiguity in critical endpoint location. Our results predict pronounced nonmonotonic shifts in the critical endpoint due to coupled electric and strange chemical potentials, and identify coherent dual-channel critical peaks in cumulant ratios at collision energies around 5 to 7 GeV. Third, regarding high-energy transport, we demonstrated that jet quenching parameters and parton energy loss exhibit sharp enhancements near the critical endpoint. Notably, heavy-quark drag transitions from collisional to radiative dominance with increasing velocity, while light-quark total energy loss is governed by stopping distance. These findings provide multi-dimensional theoretical benchmarks for mapping the QCD phase diagram in ongoing and future experiments.
