Modified gravity revealed along geodesic tracks
European Physical Journal C: Particles and Fields, 2018 The study of the dynamics of a two-body system in modified gravity constitutes a more complex problem than in Newtonian gravity. Numerical methods are typically needed to solve the equations of geodesics.

Numerical simulations of Modified Newtonian Dynamics [PDF]
Journal of Physics: Conference Series, 2016 The ΛCDM standard cosmological model is strongly supported by multiple lines of evidence, particularly from observations at large scales such as the CMB and large scale structure. There are some indications, however, of problems at smaller scales. An alternative to the CDM approach is to modify the gravitational force, as exemplified by the MOdified ...

Modified Newtonian Dynamics Close to Home [PDF]
Science, 2007 In his Perspective “Seeing through Dark Matter” (3 August, p. 607), Stacy McGaugh describes the success of a modified Newtonian dynamics (MOND) in explaining the flat rotation curves of galaxies without invoking dark matter.

The Effects of Minimal Length in Entropic Force Approach
Advances in High Energy Physics, 2013 With Verlinde’s recent proposal which says that gravity can be identified with an entropic force and considering the effects of generalized uncertainty principle in the black hole entropy-area relation we derive the modified equations for Newton’s law of

MOND: uma alternativa à mecânica newtoniana [PDF]
Revista Brasileira de Ensino de Física, 2008 O objetivo do presente trabalho é expor os principais aspectos e resultados de uma das mais populares alternativas à teoria newtoniana para o movimento dos corpos conhecida por Modified Newtonian Dynamics (MOND, na sigla em inglês).

A quantum state for the late Universe
Physics Letters B, 2022 We consider the quantum description of a toy model universe in which the Schwarzschild-de Sitter geometry emerges from the coherent state of a massless scalar field.

The Magellanic Stream in Modified Newtonian Dynamics
, 2006 The dynamics of the Magellanic Stream (MS) as a series of clouds extending from the Magellanic Clouds (MCs) to the south Galactic pole is affected by the distribution and the amount of matter in the Milky Way. We calculate the gravitational effect of the

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels
Advanced Functional Materials, EarlyView.Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...
