Dynamical Local Tadpole-Improvement in Quantum Simulations of Gauge Theories
Marc Illa, Martin J. Savage, Xiaojun Yao
We identify a new element in quantum simulations of lattice gauge theories, arising from spacetime-dependent quantum corrections in the relation between the link variables defined…

Improved Honeycomb and Hyperhoneycomb Lattice Hamiltonians for Quantum Simulations of Non-Abelian Gauge Theories
Marc Illa, Martin J. Savage, Xiaojun Yao
Improved Kogut-Susskind Hamiltonians for quantum simulations of non-Abelian Yang-Mills gauge theories are developed for honeycomb (2+1D) and hyperhoneycomb (3+1D) spatial tessellat…
