Operator preconditioning of the Costabel FEM-BEM coupling for the time-harmonic Maxwell transmission problem
Quang Huy Nguyen, Van Chien Le, Kristof Cools
This paper derives an equivalent formulation of the Costabel FEM-BEM coupling for the time-harmonic Maxwell transmission problem with a Lipschitz interface, and constructs a block-…

Scalar glueball- mixing in one flavor lattice QCD
Long-Cheng Gui, Wei Sun, Ying Chen +3
We investigate the mixing between the lowest-lying scalar glueball and the meson in lattice quantum chromodynamics (QCD) utilizing an anisotropic $16^3 \tim…
