N ov 2 00 1 Sub - mm gravity : confronting the modified dynamics with higher - dimensional theories
We propose that future experiments aiming at the detection of deviations from the 1/r 2 gravitational law on submillimetric scales can be used to test the modified Newtonian dynamics theory (MOND). Current experiments are able to test the gravitational field of masses m ≈ 1g at distances r ≈ 200 µm, implying that they are probing accelerations well above the MOND limit (a 0 ≈ 1.2 × 10 −8 cms −2...

متن کاملParticle dynamics in a class of two-dimensional gravity theories.
We provide a method to determine the motion of a classical massive particle in a background geometry of 2-dimensional gravity theories, for which the Birkhoff theorem holds. In particular, we get the particle trajectory in a continuous class of 2-dimensional dilaton gravity theories that includes the Callan-Giddings-HarveyStrominger (CGHS) model, the Jackiw-Teitelboim (JT) model, and the d-dime...

متن کاملBlack holes in higher-derivative gravity theories.
We study static spherically symmetric solutions of Einstein gravity plus an action polynomial in the Ricci scalar, R, of arbitrary degree, n, in arbitrary dimension, D. The global properties of all such solutions are derived by studying the phase space of field equations in the equivalent theory of gravity coupled to a scalar field, which is obtained by a field redefinition and conformal transf...
