   Stripes from (noncommutative) stars

   J. Ambjorn🇩🇰 · S. Catterall🇺🇸

   We show that lattice regularization of noncommutative field theories can be used to study non-perturbative vacuum phases. Specifically we provide evidence for the existence of a striped phase in two-dimensional noncommutative scalar field theory

   Effects of Quenching in \Delta I=1/2 Kaon Decays

   C.J.D. Lin🇬🇧 · G. Martinelli🇮🇹 · E. Pallante🇮🇹 · C.T. Sachrajda🇬🇧 · G. Villadoro🇮🇹

   We present the inconsistencies which arise in quenched QCD in $\Delta I=1/2$ non-leptonic kaon decays using chiral perturbation theory (ChPT) to one loop. In particular we discuss how the lack of unitarity of the quenched theory invalidates the usual methods for the extraction of matrix elements from correlation functions.

   Recent lattice results relevant for heavy ion collisions

   Kazuyuki Kanaya🇯🇵

   I summarize recent lattice results on QCD at finite temperatures and densities. Studies on the nature of the QCD transition at the physical point, continuum extra polations of thermodynamic quantities, and new calculations of hadronic spectral functions applying the maximum entropy method are discussed. Recent advances in finite density QCD are also reviewed.
