Nonlocal gravity and structure in the Universe
The observed acceleration of the Universe can be explained by modifying general relativity. One such attempt is the nonlocal model of Deser and Woodard. Here we fix the background cosmology usingExpand

Structure formation in a nonlocally modified gravity model
We study a nonlocally modified gravity model proposed by Deser and Woodard [Phys. Rev. Lett. 99, 111301 (2007)] which gives an explanation for current cosmic acceleration. By deriving and solving theExpand

Solving the effective field equations for the Newtonian potential
Loop corrections to the gravitational potential are usually inferred from scattering amplitudes, which seems quite different from how the linearized Einstein equations are solved with a static, pointExpand

Quantum scalar corrections to the gravitational potentials on de Sitter background
A bstractWe employ the graviton self-energy induced by a massless, minimally coupled (MMC) scalar on de Sitter background to compute the quantum corrections to the gravitational potentials of aExpand

Observational Constraints in Nonlocal Gravity: the Deser-Woodard Case
We study the cosmology of a specific class of nonlocal model of modified gravity, the so-called Deser-Woodard (DW) model, modifying the Einstein-Hilbert action by a term $\sim R f(\Box^{-1}R)$, whereExpand

Solvation dynamics by coherence period resolved transient grating.
We report a third-order nonlinear time-domain method, coherence period (τ) resolved transient grating (TRTG), that gives accurate solvation dynamics free from population relaxation in a short dataExpand

Investigation of a new willemite-type compound, (Li, Na, H)0.16Zn1.92SiO4
Abstract A new willemite-type compound, [(Li, Na, H)0.16Zn1.92SiO4)] was synthesized from both solid-state reactions and molten NaCl. X-ray single crystal and neutron powder diffraction studiesExpand

Analysis of the wetting state of super-repellent fabrics with liquids of varying surface tension
In designing a super-repellent surface that is not wet to liquids with a lower surface tension than water, micro and nano-scale surface roughness have a great impact in addition to low surfaceExpand

The first study of antiferromagnetic eosphorite-childrenite series (Mn1−xFex)AlP(OH)2H2O (x=0.5)
This study presents for the first time the antiferromagnetic structure of the eosphorite-childrenite series (Mn1-xFex)AlPO4(OH)2H2O (x=0.5), based on neutron single crystal diffraction at 3 K inExpand
