In relativistic space-time, Bohmian theories can be formulated by introducing a privileged foliation of space-time. The introduction of such a foliation – as extra absolute space-time structure – would seem to imply a clear violation of Lorentz invariance, and thus a conflict with fundamental relativity. Here, we consider the possibility that, instead of positing it as extra structure, the required foliation could be covariantly determined by the wave function. We argue that this allows for the formulation of Bohmian theories that seem to qualify as fundamentally Lorentz invariant. We conclude with some discussion of whether or not they might also …

The important identity of a responsible media is playing an unbiased role in reporting a matter without giving unnecessary hype to attract the attention of the gullible public with the object of making money and money only.After reporting properly the media can educate the public to form their own opinion in the matters of public interest. Throughout the centuries, the world has never existed without information and communication, hence the inexhaustible essence of mass media. The government has the power to either make or reject whatever that will exist within its environment. It also determines how free the mass media …

Yet Another Snapshot Of Foundational Attitudes Toward Quantum Mechanics, Travis Norsen, Sarah Nelson
Physics: Faculty Publications
A survey probing respondents' views on various foundational issues in quantum mechanics was recently created by Schlosshauer, Kofler, and Zeilinger [arXiv:1301.1069] and then given to 33 participants at a quantum foundations conference. Here we report the results of giving this same survey to the attendees at another recent quantum foundations conference. While it is rather difficult to conclude anything of scientific significance from the poll, the results do strongly suggest several interesting cultural facts -- for example, that there exist, within the broad field of "quantum foundations", sub-communities with quite different views, and that (relatedly) there is probably …
The Fine-Tuning Of Nomic Behavior In Multiverse Scenarios, Max Lewis Edward Andrews
The Fine-Tuning Of Nomic Behavior In Multiverse Scenarios, Max Lewis Edward Andrews
Masters Theses
The multiverse hypothesis (the view that there is not just one world or universe in existence, bur rather that there are many) is the leading alternative to the competing fine-tuning hypothesis (the laws of physics and constants are fine-tuned for the existence of life). The multiverse dispels many aspects of the fine-tuning argument by suggesting that there are different initial conditions in each universe, varying constants of physics, and the laws of nature lose their known arbitrary values; thus, making the previous single-universe argument from fine- tuning incredibly weak. The position that will be advocated will be that a form …
On The Physical Explanation For Quantum Computational Speedup, Michael Cuffaro
On The Physical Explanation For Quantum Computational Speedup, Michael Cuffaro
Electronic Thesis and Dissertation Repository
The aim of this dissertation is to clarify the debate over the explanation of quantum speedup and to submit, for the reader’s consideration, a tentative resolution to it. In particular, I argue that the physical explanation for quantum speedup is precisely the fact that the phenomenon of quantum entanglement enables a quantum computer to fully exploit the representational capacity of Hilbert space. This is impossible for classical systems, joint states of which must always be representable as product states. I begin the dissertation by considering, in Chapter 2, the most popular of the candidate physical explanations for quantum speedup: the …
