Dynamics of the self-interacting chameleon cosmology
Hossein Farajollahi, Amin Salehi
In this article we study the properties of the flat FRW chameleon cosmology in which the cosmic expansion of the Universe is affected by the chameleon field and dark energy. In par…
Constraints on scalar-tensor theories from observations
Hossein Farajollahi, Amin Salehi, Mohammad Nasiri
We study the dynamical description of scalar-tensor gravity by performing the best-fit analysis for two cases of exponential and power-law form of the potential and scalar field fu…
Stability analysis of agegraphic dark energy in Brans-Dicke cosmology
H. Farajollahi, J. Sadeghi, M. Pourali +1
Stability analysis of agegraphic dark energy in Brans-Dicke theory is presented in this paper. We constrain the model parameters with the observational data and thus the results be…
Anisotropic conductance at improper ferroelectric domain walls
Dennis Meier, Jan Seidel, Andres Cano +6
Transition metal oxides hold great potential for the development of new device paradigms because of the field-tunable functionalities driven by their strong electronic correlations…
Extension of the Schiff theorem to ions and molecules
V. V. Flambaum, A. Kozlov
According to the Schiff theorem the nuclear electric dipole moment (EDM) is screened in neutral atoms. In ions this screening is incomplete. We extend a derivation of the Schiff th…
On the Distribution of Atkin and Elkies Primes
Igor E. Shparlinski, Andrew V. Sutherland
Given an elliptic curve E over a finite field F_q of q elements, we say that an odd prime ell not dividing q is an Elkies prime for E if t_E^2 - 4q is a square modulo ell, where t_…
High temperature series expansion study of the Heisenberg antiferromagnet on the hyperkagome lattice: Comparison with NaIrO
R. R. P. Singh, J. Oitmaa
We develop high temperature series expansions for and the uniform structure factor of the spin-half Heisenberg model on the hyperkagome lattice to order . These ex…
Cosmic acceleration and phantom crossing in -gravity
H. Farajollahi, A. Ravanpak, P. Wu
In this paper, we propose two new models in gravity to realize universe acceleration and phantom crossing due to dark torsion in the formalism. The model parameters are cons…
The dynamical evolution of dwarf planet (136108) Haumea's collisional family: General properties and implications for the trans-Neptunian belt
Patryk Sofia Lykawka, Jonathan Horner, Tadashi Mukai +1
Recently, the first collisional family was identified in the trans-Neptunian belt. The family consists of Haumea and at least ten other ~100km-sized trans-Neptunian objects (TNOs)…
Pervasive Flexibility in Living Technologies through Degeneracy Based Design
James Whitacre, Axel Bender
The capacity to adapt can greatly influence the success of systems that need to compensate for damaged parts, learn how to achieve robust performance in new environments, or exploi…
Analysis of Hydrogen Cyanide Hyperfine Spectral Components towards Star Forming Cores
Robert M. Loughnane, Matt P. Redman, Eric R. Keto +2
Although hydrogen cyanide has become quite a common molecular tracing species for a variety of astrophysical sources, it, however, exhibits dramatic non-LTE behaviour in its hyperf…
High-order Ho multipoles in HoB2C2 observed with soft resonant x-ray diffraction
A. J. Princep, A. M. Mulders, E. Schierle +7
Soft resonant x-ray Bragg diffraction (SRXD) at the Ho M edges has been used to study Ho multipoles in the combined magnetic and orbitally ordered phase of HoBC$_2…
Ultra-shallow quantum dots in an undoped GaAs/AlGaAs 2D electron gas
W. Y. Mak, F. Sfigakis, K. Das Gupta +7
We report quantum dots fabricated on very shallow 2-dimensional electron gases, only 30 nm below the surface, in undoped GaAs/AlGaAs heterostructures grown by molecular beam epitax…
Corrections to Pauling residual entropy and single tetrahedron based approximations for the pyrochlore lattice Ising antiferromagnet
Rajiv R. P. Singh, J. Oitmaa
We study corrections to single tetrahedron based approximations for the entropy, specific heat and uniform susceptibility of the pyrochlore lattice Ising antiferromagnet, by a Nume…
CloudGenius: Automated Decision Support for Migrating Multi-Component Enterprise Applications to Clouds
Michael Menzel, Rajiv Ranjan
One of the key problems in migrating multi-component enterprise applications to Clouds is selecting the best mix of VM images and Cloud infrastructure services. A migration process…
Ground state properties, excitation spectra and phase transitions in the and bilayer Heisenberg models on the honeycomb Lattice
J. Oitmaa, R. R. P. Singh
Motivated by the observation of a disordered spin ground state in the material BiMnONO, we study the ground state properties and excitation spectra of th…
Curvaton reheating and intermediate inflation in brane cosmology
H. Farajollahi, A. Ravanpak
In this paper, we study the curvaton reheating mechanism for an intermediate inflationary universe in brane world cosmology. In contrast to our previous work, we assume that when t…
