“…The 2) for the free streaming part was recently studied in Ref. [21,22,23,24] for massive quarks, extending the recent development of chiral kinetic theory for massless chiral quarks [36,37,38,39,40,41,42], for which a Berry's curvature in momentum space due to spin projection plays a critical role. The 1) is also expected to be intimately related to the "side-jump" phenomenon in chiral kinetic theory [43,44,45].…”

We present the quantum kinetic equation for spin polarization of massive quarks in leading log order of perturbative QCD, which describes time evolution of the spin density matrix in momentum space of a massive quark interacting with a background QCD plasma. We find that the time evolution operator of the spin density matrix, or the quantum kinetic collision terms, are universally of order α 2 s log(1/α s ) in terms of the QCD coupling constant α s = g 2 /(4π). Our quantum kinetic equation is valid for an arbitrary quark mass m m D ∼ gT , where m D is the Debye mass, and can be used to study relaxation dynamics of spin polarization of massive quarks in perturbative QCD

“…In CKT, the chiral anomaly is encoded through the Berry curvature [25], which modifies the Boltzmann equation and the phase space measure. Recently, various aspects of the CKT were investigated, including the Lorentz covariance [22,23,26,27], consistent versus covariant anomalies [28,29], particle collisions [22,27,30,31], etc.…”

Many-body systems with chiral fermions exhibit anomalous transport phenomena originated from quantum anomalies. Based on quantum field theory, we derive the kinetic theory for chiral fermions interacting with an external electromagnetic field in a background curved geometry. The resultant framework is U(1) gauge invariant and local Lorentz and diffeomorphism covariant. It is particularly useful to study the gravitational or non-inertial effects for chiral fermions. As the first application, we study the chiral dynamics in a rotating coordinate and clarify the roles of the Coriolis force and spin-vorticity coupling in generating the chiral vortical effect. We also show that the chiral vortical effect is an intrinsic phenomenon of a rotating chiral fluid, and thus independent of the observer's frame.

“…[20,21] from the Wigner-function approach based on quantum field theory with the motivation to explore non-equilibrium transport in chiral matter beyond the renown anomalous phenomena in equilibrium such as the chiral magnetic/vortical effects [22][23][24]. There have been also plenty of followup studies for extension and applications [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. In particluar, the issue for Lorentz covariance associated with the side-jump phenomenon was addressed in refs.…”

We systematically derive the collision term for the axial kinetic theory, a quantum kinetic theory delineating the coupled dynamics of the vector/axial charges and spin transport carried by the massive spin-1/2 fermions traversing a medium. We employ the Wigner-function approach and propose a consistent power-counting scheme where the axial-charge distribution function, a non-conserved quantity for massive particles, is accounted as the first-order quantity in the expansion, while the vector-charge distribution function the zeroth-order quantity. This specific power-counting scheme allows us to organize a reduced expansion for the collision term and to formally identity the spindiffusion effect and the spin-polarization effect at the same order. We confirm that the obtained collisional axial kinetic theory smoothly reduces to the chiral kinetic theory in the massless limit, serving as a consistency check. In the absence of electromagnetic fields, we further present the simplified axial kinetic equations suitable for tracking dynamical spin polarization of heavy and light fermions, respectively. As an application to the weakly coupled quark-gluon plasma at high temperature, we compute the spin-diffusion term for massive quarks within the leading-log approximation. The formal expression for the firstorder terms provides a path toward evaluation of the spin polarization effect in quantum chromodynamics.
