Description
During the last two years, simulations with domain wall fermions at physical quark masses have been done at zero and non-zero temperature by the RBC and UKQCD Collaborations and the HotQCD Collaboration. Precision measurements of zero temperature observables,
such as the kaon semileptonic form factor and B_K have been done. More challenging observables, such as K to pi pi weak decay amplitudes have been calculated, for I = 2 final states, and are being calculated, for I = 0 final states. There have also been calculations of the QCD finite temperature phase transition with domain wall fermions, where for the first time the lattice formulation manifests the full symmetries that play a role in the transition. These topics, plus newer calculations, will be discussed.
