Single-particle digitization strategy for quantum computation of a scalar field theory
João Barata, Niklas Mueller, Andrey Tarasov +1
Motivated by the parton picture of high energy quantum chromodynamics, we develop a single-particle digitization strategy for the efficient quantum simulation of relativistic scatt…
Multiple classical limits in relativistic and nonrelativistic quantum mechanics
N. Yokomizo, J. C. A. Barata
The existence of a classical limit describing interacting particles in a second-quantized theory of identical particles with bosonic symmetry is proved. This limit exists in additi…
Topological low-temperature limit of Z(2) spin-gauge theory in three dimensions
N. Yokomizo, P. Teotonio-Sobrinho, J. C. A. Barata
We study Z(2) lattice gauge theory on triangulations of a compact 3-manifold. We reformulate the theory algebraically, describing it in terms of the structure constants of a bidime…
Dyonic Sectors and Intertwiner Connections in 2+1-dimensional Lattice Z_N-Higgs Models
J. C. A. Barata, F. Nill
We construct dyonic states in 2+1-dimensional lattice Z_N-Higgs models, i.e., states which are both, electrically and magnetically charged. The associated Hilbert spaces carry char…
Electrically and Magnetically Charged States and Particles in the 2+1-Dimensional Z_N-Higgs Gauge Model
Joao C A Barata, Florian Nill
Electrically as well as magnetically charged states are constructed in the 2+1-dimensional Euclidean Z_N-Higgs lattice gauge model, the former following ideas of Fredenhagen and Ma…
