Quantum simulation on trapped ions shows that a plaquette term in a 2+1D U(1) gauge theory enables string propagation in the plane and extended matter creation, realizing genuine two-dimensional dynamics.
A multi-part truncation for lattice QCD with fermions enables explicit Hamiltonians in 1+1D and 2+1D and string-breaking simulations by capping basis states, electric energy, fermions per site, and using large-Nc matrix element scaling.
Gauged Gaussian PEPS ansatz demonstrated on Z2 gauge theory with dynamical fermions, agreeing with exact diagonalization on small lattices and feasible for larger ones.
