Quantum state reduction, and Newtonian twistor theory
Maciej Dunajski, Roger Penrose
We discuss the equivalence principle in quantum mechanics in the context of Newton--Cartan geometry, and non--relativistic twistor theory.
Gluing Noncommutative Twistor Spaces
Matilde Marcolli, Roger Penrose
We describe a general procedure, based on Gerstenhaber-Schack complexes, for extending to quantized twistor spaces the Donaldson-Friedman gluing of twistor spaces via deformation t…
Stephen William Hawking: A Biographical Memoir
Bernard J. Carr, George F. R. Ellis, Gary W. Gibbons +5
Stephen Hawking's contributions to the understanding of gravity, black holes and cosmology were truly immense. They began with the singularity theorems in the 1960s followed by his…
A new laser-ranged satellite for General Relativity and space geodesy: III. De Sitter effect and the LARES 2 space experiment
Ignazio Ciufolini, Richard Matzner, Vahe Gurzadyan +1
In two previous papers we presented the LARES 2 space experiment aimed at a very accurate test of frame-dragging and at other tests of fundamental physics and measurements of space…
A new laser-ranged satellite for General Relativity and space geodesy: I. An introduction to the LARES2 space experiment
Ignazio Ciufolini, Antonio Paolozzi, Erricos C. Pavlis +8
We introduce the LARES 2 space experiment recently approved by the Italian Space Agency (ASI). The LARES 2 satellite is planned for launch in 2019 with the new VEGA C launch vehicl…
An Improved Test of the General Relativistic Effect of Frame-Dragging Using the LARES and LAGEOS Satellites
Ignazio Ciufolini, Antonio Paolozzi, Erricos C. Pavlis +7
We report the improved test of frame-dragging, an intriguing phenomenon predicted by Einstein's General Relativity, obtained using 7 years of Satellite Laser Ranging (SLR) data of…
