Entrance channel mass asymmetry dependence of compound nucleus formation
Abstract The fusion reactions 48Ca+ 154Sm and 16O+ 186W leading to the same compound nucleus 202Pb are studied within the framework of an improved isospin dependent quantum molecular dynamics model. The...

Domain wall solutions with Abelian gauge fields
Abstract We study kink (domain wall) solutions in a model consisting of two complex scalar fields coupled to two independent Abelian gauge fields in a Lagrangian that has U(1)×U(1) gauge plus Z 2 ...

A description of Schwarzschild black holes in terms of intersecting M-branes and antibranes
Abstract Intersecting M-branes are known to describe multi-charged black holes. Using a configuration of such intersecting branes and antibranes, together with massless excitations living on them, we give a description of Schwarzschild black holes...

Charged balanced black rings in five dimensions
Abstract We present balanced black ring solutions of pure Einstein–Maxwell theory in five dimensions. The solutions are asymptotically flat, and their tension and gravitational self-attraction are balanced by the repulsion due to rotation and...

Bohr Hamiltonian with deformation-dependent mass term
Abstract The Bohr Hamiltonian describing the collective motion of atomic nuclei is modified by allowing the mass to depend on the nuclear deformation. Exact analytical expressions are derived for spectra and wave functions in the case of a...

A simple model of neutrino masses from supersymmetry breaking
Abstract We analyze a class of supersymmetric models first introduced by Arkani-Hamed et al. and Borzumati et al. in which the light neutrino masses result from higher-dimensional supersymmetry-breaking terms in the MSSM super-potentials and Kahler...

Cosmological constraints on the modified entropic force model
Abstract Very recently, Verlinde considered a theory in which space is emergent through a holographic scenario, and proposed that gravity can be explained as an entropic force caused by changes in the information associated with the positions of...

Noncommutative (super) p-branes and Moyal–Yang star products with a lower and upper scale
Abstract Noncommutative p-brane actions, for even ( p + 1 = 2 n )-dimensional...

The structure and motion of the self-interstitial in diamond
Abstract We have made self-consistent semi-empirical molecular orbital calculations for various possible self-interstitial geometries in diamond, both with and without lattice distortion. Total energies are obtained, not merely the sum of...

Quantum Monte-Carlo Study of Magnetic Ordering in ZnV2O4
Abstract We study the magnetic ordering of Vanadium spinels by Quantum Monte Carlo simulations of a three-band Hubbard model. Vanadium spinels, AV2O4, exhibit a unique “up-up-down-down” spin ordering at low temperatures. While this magnetic ordering ...

Maximally helicity violating disk amplitudes, twistors and transcendental integrals
Abstract We obtain simple expressions for tree-level maximally helicity violating amplitudes of N gauge bosons from disk world-sheets of open superstrings. The amplitudes are written in terms of ( N ...

Magnetic Order and Frustrated Dynamics in Li (Ni0.8Co0.1Mn0.1)O2: A Study by μ+SR and SQUID Magnetometry
Abstract Recently, the mixed transition metal oxides of the form Li (Ni1−y−zCoyMnz)O2, havebecome the center of attention as promising candidates for novel battery material. These materials have also revealed very interesting magnetic properties due ...

The sum-of-digits function of canonical number systems: Distribution in residue classes
Abstract In the present paper we investigate the sum-of-digits function for canonical number systems. We are interested in its re-partition in arithmetic progressions and similar results for sum sets. The original problem goes back to Gelfond, who...

Renormalization of composite operators in time-dependent backgrounds
Abstract We study the phenomenon of composite operator renormalization and mixing in systems where time-translational invariance is broken and the evolution is out-of-equilibrium. We show that composite operators mix also through non-local memory...

Fermat-linked relations for the Boubaker polynomial sequences via Riordan matrices analysis
Abstract The Boubaker polynomials are investigated in this paper. Using a Riordan matrices analysis, a sequence of relations outlining the relations with Chebyshev and Fermat polynomials has been obtained. The obtained expressions are a meaningful...
