Hamiltonian limit of lattice QED in 2+1 dimensions
L. Funcke, C. F. Groß, K. Jansen +3
The Hamiltonian limit of lattice gauge theories can be found by extrapolating the results of anisotropic lattice computations, i.e., computations using lattice actions with differe…
Twisted mass ensemble generation on GPU machines
Bartosz Kostrzewa, Simone Bacchio, Jacob Finkenrath +4
We present how we ported the Hybrid Monte Carlo implementation in the tmLQCD software suite to GPUs through offloading its most expensive parts to the QUDA library. We discuss our…
Defining Canonical Momenta for Discretised SU(2) Gauge Fields
Marco Garofalo, Tobias Hartung, Karl Jansen +3
In this proceeding contribution we discuss how to define canonical momenta for SU(N) lattice gauge theories in the Hamiltonian formalism in a basis where the gauge field operators…
Leading Isospin Breaking effects in nucleon and masses
Simone Romiti
We present a lattice calculation of the leading corrections to the masses of nucleons and resonances. These are obtained in QCD+QED at st order in the Isospin Breaking param…
The neutron-proton mass difference
Simone Romiti
We present a lattice calculation of the mass difference between neutron and proton, for which we find . This is obtained at 1st order in the $Q…
