(February 2, 1996) We investigate numerically the statistical properties of spectra of two-dimensional disordered systems by using the decimation method applied to the Anderson model. Statistics of the spacings calculated for system size up to 1024 × 1024 lattice sites exhibits a crossover between Wigner and Poisson distributions. We perform a selfcontained finite-size scaling analysis to find ...

in present work, we have calculated the electronic properties including density of states (dos) and electron density for gan, inn and in wurtzite phase for x=0.5. the study is based on density functional theory (dft) with full potential linearized augmented plane wave method (fp-lapw) by generalized gradient approximation (gga-pbesol) for calculating electronic properties. in this report we con...

since the beginning of human history, one of the basic dilemmas that every political institution must solve is how to exercise legitimate authority- that is, how to govern with the consent. “you can’t sit on bayonets,” goes an old political expression. this is a way of saying that although a state can exercise its power through the use of police force or coercion, in the long run the use of for...

We report on the observation of triatomic Efimov resonances in an ultracold gas of cesium atoms. Exploiting the wide tunability of interactions resulting from three broad Feshbach resonances in the same spin channel, we measure magnetic-field dependent three-body recombination loss. The positions of the loss resonances yield corresponding values for the three-body parameter, which in universal ...

Timed game automata are used for solving control problems on real-time systems. A timed reachability game consists in finding a strategy for the controller for the system, modeled as a timed automaton. Such a controller says when and which of some "controllable" actions should be taken in order to reach "goal" states. We deal with a parametric version of timed game automata. We define parametri...

Within a phenomenological approach possible forms of the order parameter of the superfluid phases of 3He in a vicinity of the transition temperature are discussed. Effect of aerogel is described by a random tensor field interacting with the orbital part of the order parameter. With respect to their interaction with the random tensor field a group of ”robust” order parameters which can maintain ...

By recasting the Klein–Gordon equation as an eigen-equation in coupling parameter [Formula: see text] basic comparison theorem may be written text], where and are monotone nondecreasing shapes of two central potentials on text]. Meanwhile, corresponding parameters that functions energy We weaken sufficient condition for ground-state spectral ordering by proving (for example dimension) if coupli...
