Finite-temperature study of eight-flavor SU(3) gauge theory [PDF]
, 2015 We present new lattice investigations of finite-temperature transitions for SU(3) gauge theory with Nf=8 light flavors. Using nHYP-smeared staggered fermions we are able to explore renormalized couplings $g^2 \lesssim 20$ on lattice volumes as large as ...

A combined finite volumes ‐ finite elements method for a low‐Mach model
International Journal for Numerical Methods in Fluids, 2017 In this paper, we develop a finite volumes ‐ finite elements method based on a time splitting to simulate some low‐Mach flows. The mass conservation equation is solved by a vertex‐based finite volume scheme using a τ‐limiter.

N-point and higher-genus osp(1|2) fusion [PDF]
, 2002 We study affine osp(1|2) fusion, the fusion in osp(1|2) conformal field theory, for example. Higher-point and higher-genus fusion is discussed. The fusion multiplicities are characterized as discretized volumes of certain convex polytopes, and are ...

Finite size scaling in CP(N-1) models
, 1993 Finite size effects in Euclidean ${\rm CP}^{N-1}$ models with periodic boundary conditions are investigated by means of the $1/N$ expansion and by Monte Carlo simulations.

Current renormalization in finite volume
Physics Letters B, 2007 For finite volume field theories with discrete translational invariance, conserved currents can be additively renormalized by infrared effects. We demonstrate this for pions using chiral perturbation theory coupled to electromagnetism in a periodic box. Gauge invariant single particle effective theories are constructed to explain these results. In such

Pion mass dependence of the $K_{l3}$ semileptonic scalar form factor within finite volume
, 2011 We calculate the scalar semileptonic kaon decay in finite volume at the momentum transfer $t_{m} = (m_{K} - m_{\pi})^2$, using chiral perturbation theory. At first we obtain the hadronic matrix element to be calculated in finite volume.

The Role of Contact Angle Hysteresis for Fluid Transport in Wet Granular Matter [PDF]
, 2015 The stability of sand castles is determined by the structure of wet granulates. Experimental data about the size distribution of fluid pockets are ambiguous about their origin.

Methods to Increase the Robustness of Finite-Volume Flow Models in Thermodynamic Systems
Energies, 2014 This paper addresses the issues linked to simulation failures during integration in finite-volume flow models, especially those involving a two-phase state.
