Decoherence-Free Entropic Gravity: Model and Experimental Tests

Erik Verlinde's theory of entropic gravity [arXiv:1001.0785], postulating
that gravity is not a fundamental force but rather emerges thermodynamically,
has garnered much attention as a possible resolu

Vital node identification in hypergraphs via gravity model

Hypergraphs that can depict interactions beyond pairwise edges have emerged
as an appropriate representation for modeling polyadic relations in complex
systems. With the recent surge of interest in re

Identifying influential nodes in complex networks: Effective distance gravity model

The identification of important nodes in complex networks is an area of
exciting growth due to its applications across various disciplines like disease
controlling, community finding, data mining, net

Polarizations of Gravitational Waves in the Bumblebee Gravity Model

Lorentz violation modifies the dispersion relation of gravitational waves
(GWs), and induces birefringence and anisotropy in propagation. Our study shows
that Lorentz violation can also activate multi

Deep Gravity: enhancing mobility flows generation with deep neural networks and geographic information

The movements of individuals within and among cities influence critical
aspects of our society, such as well-being, the spreading of epidemics, and the
quality of the environment. When information abo

Gravity vs radiation model: on the importance of scale and heterogeneity in commuting flows

We test the recently introduced radiation model against the gravity model for
the system composed of England and Wales, both for commuting patterns and for
public transportation flows. The analysis is

Modified Gravity Explains Dark Matter?

We explore a new horizon of modified gravity from the viewpoint of the
particle physics. As a concrete example, we take the $F(R)$ gravity to raise a
question: can a scalar particle ("scalaron") deriv

Scalar induced gravitational waves from primordial black hole Poisson fluctuations in $f(R)$ gravity

The gravitational potential of a gas of initially randomly distributed
primordial black holes (PBH) can induce a stochastic gravitational-wave (GW)
background through second-order gravitational effect

What does a measurement of mass and/or radius of a neutron star constrain: Equation of state or gravity?

Neutron stars (NSs) are thought to be excellent laboratories for determining
the equation of state (EoS) of cold dense matter. Their strong gravity suggests
that they can also be used to constrain gra

Can the graviton have a large mass near black holes?

The mass of the graviton, if nonzero, is usually considered to be very small,
e.g. of the Hubble scale, from several observational constraints. In this
paper, we propose a gravity model where the grav

Symmetron Scalar Fields: Modified Gravity, Dark Matter or Both?

Scalar fields coupled to gravity through the Ricci scalar have been
considered both as dark matter candidates and as a possible modified gravity
explanation for galactic dynamics. It has recently been

The unreasonable effectiveness of optimal transport in economics

Optimal transport has become part of the standard quantitative economics

Can Dark Matter be Geometry? A Case Study with Mimetic Dark Matter

We investigate the possibility of dark matter being a pure geometrical
effect, rather than a particle or a compact object, by exploring a specific
modified gravity model: mimetic dark matter. We prese
