In certain models of inflation, the postinflationary reheating of the Universe is not primarily due to perturbative decay of the inflaton field into particles, but proceeds through a tachyonic instability. In the process, long-wavelength modes of an unstable field, which is often distinct from the inflaton itself, acquire very large occupation numbers, which are subsequently redistributed into...

Precision calculations of flavour physics processes such as leptonic decays of pions and kaons allow for indirect searches of new physics. For instance, the Cabibbo-Kobayashi-Maskawa matrix elements $V_{ud}$ and $V_{us}$ accessible in these decays satisfy a unitarity relation within the Standard Model that can be probed with lattice QCD simulations. With a goal of (sub-)percent precision,...

We have ported one of the available software libraries for lattice gauge theory simulations, HiRep, to GPUs. The code supports simulations of higher representations of Wilson Fermions, which are strongly limited by computational expense depending on the gauge group and dimension of the Fermion representation. We present details on the implementation, algorithmic checks, and benchmarks...
