Di-lepton production from a single photon in strong magnetic fields: Vacuum dichroism
Koichi Hattori, Hidetoshi Taya, Shinsuke Yoshida
We study di-lepton production from a single photon in the presence of a strong constant magnetic field. By the use of the Ritus-basis formalism, we analytically evaluate the photon…
Wigner functions and quantum kinetic theory of polarized photons
Koichi Hattori, Yoshimasa Hidaka, Naoki Yamamoto +1
We derive the Wigner functions of polarized photons in the Coulomb gauge with the expansion applied to quantum field theory, and identify side-jump effects for massless pho…
Signatures of the vortical quark-gluon plasma in hadron yields
P Collaboration, Hidetoshi Taya, Aaron Park +10
We investigate the hadron production from the vortical quark-gluon plasma created in heavy-ion collisions. Based on the quark-coalescence and statistical hadronization models, we s…
Effective quantum kinetic theory for spin transport of fermions with collsional effects
Di-Lun Yang, Koichi Hattori, Yoshimasa Hidaka
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 c…
Note on all-order Landau-level structures of the Heisenberg-Euler effective actions for QED and QCD
Koichi Hattori, Kazunori Itakura, Sho Ozaki
We investigate the Landau-level structures encoded in the famous Heisenberg-Euler (HE) effective action in constant electromagnetic fields. We first discuss the HE effective action…
Emergent QCD Kondo effect in two-flavor color superconducting phase
Koichi Hattori, Xu-Guang Huang, Robert D. Pisarski
We show that effective coupling strengths between ungapped and gapped quarks in the two-flavor color superconducting (2SC) phase are renormalized by logarithmic quantum corrections…
