On R-linear convergence of semi-monotonic inexact augmented Lagrangians for saddle point problems

Dostál, Zdeněk; Horák, David; Vodstrčil, Petr - In: Computational Optimization and Applications 58 (2014) 1, pp. 87-103

A variant of the inexact augmented Lagrangian algorithm called SMALE (Dostál in Comput. Optim. Appl. 38:47–59, <CitationRef CitationID="CR10">2007</CitationRef>) for the solution of saddle point problems with a positive definite left upper block is studied. The algorithm SMALE-M presented here uses a fixed regularization parameter and...</citationref>

Periodic boundary conditions and the correct molecular-dynamics ensemble

White, J.A.; Román, F.L.; González, A.; Velasco, S. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 27, pp. 6705-6711

The use of periodic boundary conditions in molecular-dynamics simulations leads to the microcanonical EVNMG ensemble of … hard disks with periodic boundary conditions in the absence of external forces. We find that the periodic boundary … conditions give rise to an anomalous inhomogeneity in the density profile of the system. This inhomogeneity is only relevant for …

Influence of boundary conditions on level statistics and eigenstates at the metal–insulator transition

Schweitzer, L.; Potempa, H. - In: Physica A: Statistical Mechanics and its Applications 266 (1999) 1, pp. 486-491

We investigate the influence of the boundary conditions on the scale invariant critical level statistics at the metal–insulator transition of disordered three-dimensional orthogonal and two-dimensional unitary and symplectic tight-binding models. The distribution of the spacings between...
