Optimized Folding Simulations of Protein A
S. Trebst, U. H. E. Hansmann
We describe optimized parallel tempering simulations of the 46-residue B-fragment of protein A. Native-like configurations with a root-mean-square deviation of approximately 3A to…
Localized eigenmodes of the overlap operator and their impact on the eigenvalue distribution
Anna Hasenfratz, Roland Hoffmann, Stefan Schaefer
In a system where chiral symmetry is spontaneously broken, the low energy eigenmodes of the continuum Dirac operator are extended. On the lattice, due to discretization effects, th…
Parameters of the lowest order chiral Lagrangian from fermion eigenvalues
Thomas DeGrand, Stefan Schaefer
Recent advances in Random Matrix Theory enable one to determine the pseudoscalar decay constant from the response of eigenmodes of quenched fermions to an imaginary isospin chemica…
Exploring the structure of the quenched QCD vacuum with overlap fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +3
Overlap fermions have an exact chiral symmetry on the lattice and are thus an appropriate tool for investigating the chiral and topological structure of the QCD vacuum. We study va…
Understanding nucleon structure using lattice simulations
Wolfram Schroers
This review focuses on the discussion of three key results of nucleon structure calculations on the lattice. These three results are the quark contribution to the nucleon spin, J_q…
Decay constants of charm and beauty pseudoscalar heavy-light mesons on fine lattices
A. Ali Khan, V. Braun, T. Burch +4
We compute decay constants of heavy-light mesons in quenched lattice QCD with a lattice spacing of a ~ 0.04 fm using non-perturbatively O(a) improved Wilson fermions and O(a) impro…
