Abstract: The exchange of spin-0 or spin-1 bosons between fermions or spin-polarized macroscopic objects gives rise to various spin-dependent potentials. We derive the coordinate-space nonrelativistic potentials induced by the exchange of such bosons, including contact terms… read more here.

Abstract: We apply the density matrix expansion (DME) at Hartree-Fock level with long-range chiral effective field theory interactions defined in coordinate space up to next-to-next-to-leading order. We consider chiral potentials both with and without explicit Delta… read more here.

DOI: 10.1103/physrevd.96.054511
Abstract: We study the vector and axial-vector current correlators in perturbative and non-perturbative regimes of QCD. The correlators in Euclidean coordinate space are calculated on the lattice using the Mobius domain-wall fermion formulation at three lattice… read more here.
