Investigating a (3+1)D Topological -Term in the Hamiltonian Formulation of Lattice Gauge Theories for Quantum and Classical Simulations
Angus Kan, Lena Funcke, Stefan Kühn +5
Quantum technologies offer the prospect to efficiently simulate sign-problem afflicted regimes in lattice field theory, such as the presence of topological terms, chemical potentia…
Dimensional Expressivity Analysis of Parametric Quantum Circuits
Lena Funcke, Tobias Hartung, Karl Jansen +2
Parametric quantum circuits play a crucial role in the performance of many variational quantum algorithms. To successfully implement such algorithms, one must design efficient quan…
Topological vacuum structure of the Schwinger model with matrix product states
Lena Funcke, Karl Jansen, Stefan Kühn
We numerically study the single-flavor Schwinger model with a topological -term, which is practically inaccessible by standard lattice Monte Carlo simulations due to the sign pr…
Variational study of U(1) and SU(2) lattice gauge theories with Gaussian states in 1+1 dimensions
P. Sala, T. Shi, S. Kühn +3
We introduce a method to investigate the static and dynamic properties of both Abelian and non-Abelian lattice gauge models in 1+1 dimensions. Specifically, we identify a set of tr…
Efficient Basis Formulation for (1+1)-Dimensional SU(2) Lattice Gauge Theory: Spectral calculations with matrix product states
Mari Carmen Bañuls, Krzysztof Cichy, J. Ignacio Cirac +2
We propose an explicit formulation of the physical subspace for a (1+1)-dimensional SU(2) lattice gauge theory, where the gauge degrees of freedom are integrated out. Our formulati…
