Two-nucleon scattering amplitudes at light quark masses from lattice QCD

We present a lattice-QCD determination of nucleon-nucleon scattering amplitudes at pion masses of $M_\pi \approx 200$ MeV and $M_\pi \approx 280$ MeV at a single lattice spacing $a \approx 0.064$ fm on two CLS ensembles. The finite-volume energy spectra are extracted from large Hermitian correlation matrices constructe...

Scattering amplitudes from quantum hardware a la RESOs

We report the first quantum-hardware implementation of Real-time Estimators for Scattering Observables (RESOs). The physical model is a one-dimensional lattice theory of non-relativistic spin-1/2 fermions with a single contact interaction. The lattice sizes studied are up to $N_x=54$ lattice sites and up to $20$ time s...
