We carry out a finite density calculation based on a canonical approach which is designed to address the overlap problem. Two degenerate flavor simulations are performed using Wilson gauge action and Wilson fermions on 4 lattices, at temperatures close to the critical temperature Tc ≈ 170MeV and large densities (5 to 20 times nuclear matter density). In this region, we find that the algorithm w...

FermiQCD is a C++ library for fast development of parallel Lattice Quantum Field Theory computations. It has been developed following a top-down fully Object Oriented design approach with focus on simplicity of use. FermiQCD includes: a heatbath algorithm for Wilson and O(a2) improved SU(n) gauge actions; inversion algorithms for Wilson, Clover, Kogut-Susskind, Asqtad, and Domain Wall fermionic...

We describe recent results concerning the behavior of lattice QCD with light dynamical Wilson and Staggered quarks. We show that it is possible to reach regions of parameter space with light pions m 0:2=a using Wilson fermions. If the Hybrid Molecular Dynamics (HMD) algorithm is used with the same parameters it gives incorrect results. We also present preliminary results using a higher-order in...

We provide an extension of the perfect sampling algorithm of Fill (1998) to general chains, and describe how use of bounding processes can ease computational burden. Along the way, we unearth a simple connection between the Coupling From The Past (CFTP) algorithm originated by Propp and Wilson (1996) and our extension of Fill's algorithm.

We present an adaptive multigrid solver for application to the non-Hermitian Wilson-Dirac system of QCD. The key components leading to the success of our proposed algorithm are the use of an adaptive projection onto coarse grids that preserves the near null space of the system matrix together with a simplified form of the correction based on the so-called γ5-Hermitian symmetry of the Dirac oper...

introduction: the wilson disease is an autosomal recessive disease in which the liver, central nervous system, eyes, blood and other parts of the body involved. timely diagnosis and appropriate treatment of the disease requires awareness of the clinical presentations of this disease in children.methods: this case series study included 62 patients with wilson disease who admitted to children&apo...

Wilson disease is a pathology because of a gene mutation causing malfunction in the copper excretion from the organism. Therefore, copper accumulation in the human body gives rise to oxidative processes. Hence, Wilson disease causes several disorders including affecting tissues and organs. Neurological disorders leads to copper accumulation in the human body. Approximately 95% of individuals wi...
