The mimetic finite difference (MFD) method mimics fundamental properties of mathematical and physical systems including conservation laws, symmetry and positivity of solutions, duality and self-adjointness of differential operators, and exact mathematical identities of the vector and tensor calculus. This ...
We demonstrate this by studying sum rules in terms of the scalar and axial- vector matrix elements in lattice gauge calculations. The effects of eliminating backward time propagation are presented.doi:10.1103/PhysRevLett.72.1790Keh-Fei LiuShao-Jing Dong...
and determinant det() are invariants, as are the tensor eigenvalues. Just as scalar-valued functions over the vector space R 3 have gradients with values in R 3 , tensor invariants have gradients with values in Sym 3 . Adapting the notation from vector calculus, we use J(D) to represent...
because the e.m. couplingeas well as the difference betweenandare small. The weak interaction provides the neutron mass with an imaginary part and generates a shift of the real part as well, but these effects are tiny and will be neglected. The Standard Model then reduces to QED + QCD. ...
In scale-resolving simulations such as Large Eddy Simulations (LES), the spatial discretization scheme of the convective term plays a crucial role in avoiding interference between the numerical errors and the subgrid-scale model. Accurate schemes lead to lower truncation errors and better predictions ...
