Quantum Newtonian Dynamics on a Light Front [PDF]
, 1998 We recall the special features of quantum dynamics on a light-front (in an infinite momentum frame) in string and field theory. The reason this approach is more effective for string than for fields is stressed: the light-front dynamics for string is that

Newtonian and modified newtonian gravitational simulation of spiral galaxies
Iraqi Journal of Physics, 2019 One of the most powerful tools for any stellar dynamics is the N-body simulation. In an N-body simulation the motion of N particles is followed under their mutual gravitational attraction.

The Astrophysical Journal, 2023 A gravitational anomaly is found at weak gravitational acceleration g _N ≲ 10 ^−9 m s ^−2 from analyses of the dynamics of wide binary stars selected from the Gaia DR3 database that have accurate distances, proper motions, and reliably inferred stellar ...

Computing General Relativistic effects from Newtonian N-body simulations: Frame dragging in the post-Friedmann approach [PDF]
, 2013 We present the first calculation of an intrinsically relativistic quantity in fully non-linear cosmolog- ical large-scale structure studies. Traditionally, non-linear structure formation in standard {\Lambda}CDM cosmology is studied using N-body ...

Cosmological principle in Newtonian dynamics
Modern Physics Letters A, 2020 A correspondence between the equivalence principle and the homogeneity of the universe is discussed. In Newtonian gravity, translation of co-moving coordinates in a uniformly expanding universe defines an accelerated frame. A consistency condition for the invariance of this transformation which requires a well-defined transformation for the Newtonian ...

Stability of disk galaxies in the modified dynamics [PDF]
, 1998 General analytic arguments lead us to expect that in the modified dynamics (MOND) self-gravitating disks are more stable than their like in Newtonian dynamics.

Modified Newtonian dynamics and non-relativistic ChSAS gravity
Physics Letters B, 2018 In the context of the non-relativistic theories, a generalization of the Chern–Weil-theorem allows us to show that extended Chern–Simons actions for gravity in d=4 invariant under some specific non-relativistic groups lead to modified Poisson equations ...

Geometry of modified Newtonian dynamics [PDF]
Physical Review D, 2012 Modified Newtonian Dynamics is an empirical modification to Poisson's equation which has had success in accounting for the `gravitational field' $ $ in a variety of astrophysical systems. The field $ $ may be interpreted in terms of the weak field limit of a variety of spacetime geometries.

Relativistic theory of the gravitation for Modified Newtonian Dynamics
Revista de Investigación de Física, 2023 Modified Newtonian dynamics (MOND) is a hypothesis that proposes a modification of Newton's law of universal gravitation to account for observed properties of galaxies. This theory is an alternative to the hypothesis of dark matter in terms of explaining

Droplet Dynamics of Newtonian and Inelastic Non-Newtonian Fluids in Confinement
Micromachines, 2017 Microfluidic droplet technology has been developing rapidly. However, precise control of dynamical behaviour of droplets remains a major hurdle for new designs.
