The Equivalence Principle Revisited [PDF]

open access: yes, 2002
A precise formulation of the strong Equivalence Principle is essential to the understanding of the relationship between gravitation and quantum mechanics.

Quark Soup al dente: Applied Superstring Theory [PDF]

open access: yes, 2008
We discuss the application of the AdS/CFT correspondence to possibly gain new physical insights for the strongly coupled quark-gluon plasma. This article provides an informal summary of a talk given by RCM at the 18th International Conference on General ...

Effect of Some Modified Models of Gravity on the Radial Velocity of Binary Systems

open access: yesUniverse, 2022
For many classes of astronomical and astrophysical binary systems, long observational records of their radial velocity V, which is their directly observable quantity, are available.

Prospects for comparison of matter and antimatter gravitation with ALPHA-g

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
The ALPHA experiment has recently entered an expansion phase of its experimental programme, driven in part by the expected benefits of conducting experiments in the framework of the new AD + ELENA antiproton facility at CERN.

Gravitation from entanglement in holographic CFTs [PDF]

open access: yes, 2013
A bstractEntanglement entropy obeys a ‘first law’, an exact quantum generalization of the ordinary first law of thermodynamics. In any CFT with a semiclassical holographic dual, this first law has an interpretation in the dual gravitational theory as a ...

Statistical Mechanics-Based Schrödinger Treatment of Gravity

open access: yesEntropy, 2019
The entropic gravity conception proposes that what has been traditionally interpreted as unobserved dark matter might be merely the product of quantum effects.

Bound Orbits and Epicyclic Motions around Renormalization Group Improved Schwarzschild Black Holes

open access: yesUniverse, 2022
We study timelike particles’ bound orbits around renormalization group improved Schwarzschild black holes (RGISBHs), which originate from renormalization group improvement of the Einstein–Hilbert action by using the running Newton constant.

Adam Smith et la physique de Newton

open access: yesŒconomia, 2012
In most of Smith's writings we find references to the natural philosophy of Newton. Beyond the use of Newtonian concepts and laws to deal with specific issues, we would like to focus on the relationship between the Smithian representation of the social ...
