Exploring the phase structure of the multi-flavor Schwinger model with quantum computing
Lena Funcke, Tobias Hartung, Karl Jansen +4
We propose a variational quantum eigensolver suitable for exploring the phase structure of the multi-flavor Schwinger model in the presence of a chemical potential. The parametric…

Track reconstruction at the LUXE experiment using quantum algorithms
Arianna Crippa, Lena Funcke, Tobias Hartung +8
LUXE (Laser Und XFEL Experiment) is a proposed experiment at DESY which will study Quantum Electrodynamics (QED) in the strong-field regime, where QED becomes non-perturbative. Mea…

O(3) nonlinear sigma model in 1+1 dimensions with matrix product states
Falk Bruckmann, Karl Jansen, Stefan Kühn
We numerically study the spectral properties, the entanglement and the zero-temperature phase structure at nonvanishing chemical potential of the O(3) nonlinear sigma model. Using…
