Collapse and Relativity
نویسنده
چکیده
Ever since we have been in the possession of quantum theories without observers, such as Bohmian mechanics or the Ghirardi–Rimini–Weber (GRW) theory of spontaneous wave function collapse, a major challenge in the foundations of quantum mechanics is to devise a relativistic quantum theory without observers. One of the difficulties is to reconcile nonlocality with relativity. I report about recent progress in this direction based on the GRW model: A relativistic version of the model has been devised for the case of N noninteracting (but entangled) particles. A key ingredient was to focus not on the evolution of the wave function but rather on the evolution of the matter in space-time as determined by the wave function.

On peaceful coexistence: is the collapse postulate incompatible with relativity?
In this paper, it is argued that the prima facie conflict between special relativity and the quantum-mechanical collapse postulate is only apparent, and that the seemingly incompatible accounts of entangled systems undergoing collapse yielded by different reference frames can be regarded as no more than differing accounts of the same processes and events. Attention to the transformation propert...
متن کاملNaked Singularity, Black-hole and the Mass Loss in a Spherically Symmetric Gravitational Collapse
A distinguishable physical property between a naked singularity and a black-hole, formed during a gravitational collapse has important implications for both experimental and theoretical relativity. We examine the energy radiated during the spherically symmetric Gravitational collapse in this context within the framework of general relativity. It is shown that total energy radiated( Mass Loss) d...
متن کاملA naturalness argument for covered and naked singularities in gravitational collapse
We give a naturalness argument to show that both covered and naked singularities should occur generically in spherical gravitational collapse in classical general relativity, subject to the assumption of the dominant energy condition. An outstanding open problem in classical general relativity and relativistic astrophysics is to determine the final fate of the continual gravitational collapse o...
متن کاملC.G.Timpson and H.R.Brown Entanglement and Relativity ∗
This paper surveys some of the questions that arise when we consider how entanglement and relativity are related via the notion of non-locality. We begin by reviewing the role of entangled states in Bell inequality violation and question whether the associated notions of non-locality lead to problems with relativity. The use of entanglement and wavefunction collapse in Einstein's famous incompl...
متن کامل3D collapse of rotating stellar iron cores in general relativity including deleptonization and a nuclear equation of state.
We present 2D and 3D simulations of the collapse of rotating stellar iron cores in general relativity employing a nuclear equation of state and an approximate treatment of deleptonization. We compare fully general relativistic and conformally flat evolutions and find that the latter treatment is sufficiently accurate for the core-collapse supernova problem. We focus on gravitational wave (GW) e...
متن کاملCollapse of a Rotating Supermassive Star to a Supermassive Black Hole: Fully Relativistic Simulations
We follow the collapse in axisymmetry of a uniformly rotating, supermassive star (SMS) to a supermassive black hole (SMBH) in full general relativity. The initial SMS of arbitrary mass M is marginally unstable to radial collapse and rotates at the mass-shedding limit. The collapse proceeds homologously early on and results in the appearance of an apparent horizon at the center. Although our int...
