The Non-Abelian Casimir Effect for Plates, Symmetrical Tube and Box on the Lattice
B. A. Ngwenya, A. K. Rothkopf, W. A. Horowitz
We present non-perturbative results of the Casimir potential in non-abelian SU(3) gauge theory in (2+1)D and (3+1)D in the confined and deconfined phase. For the first time, geomet…

Exact space-time symmetry conservation and automatic mesh refinement for classical lattice field theory
A. Rothkopf, W. A. Horowitz, J. Nordström
The breaking of space-time symmetries and the non-conservation of the associated Noether charges constitutes a central artifact in lattice field theory. In prior work we have shown…
