From Bohr to Bayes: Causality, Probability, and Statistics in Quantum Theory.
Arkady Plotnitsky - Purdue University
This paper critically examines the view of quantum mechanics that emerged shortly after the introduction of quantum mechanics and that has been widespread ever since. Although N. Bohr, P. A. M. Dirac, and W. Heisenberg advanced this view earlier, it is best exemplified by J. von Neumann’s argument…
Meson widths from string worldsheet instantons.
Thomas Faulkner - University of Illinois Urbana-Champaign
We discuss various properties of holographic mesons in a deconfined strongly coupled plasma. We show that such mesons obtain a width from a non-perturbative effect. On the string theory side this is due to open string modes on a D-brane tunneling into a black hole through worldsheet instantons. On…
Gravitoelectromagnetism
Edmund Bertschinger - Massachusetts Institute of Technology (MIT) - Department of Physics
Gravitomagnetism is a subtle concept. Adding Lorentz invariance to Newtonian gravity leads to magnetism, but Einsteinian gravitomagnetism differs from Maxwell\'s electromagnetism. The differences lead to confusion when Lense-Thirring precession is wrongly ascribed to gyroscopes, and when authors…
Curved space, monsters and black hole entropy
I discuss a class of compact objects (\'monsters\') with more entropy than a black hole of the same ADM mass. Such objects are problematic for AdS/CFT duality and the conventional interpretation of black hole entropy as counting of microstates. Nevertheless, monster initial data can be constructed…
Astrophysics and Cosmology through Problems - 12B
Mark Wyman - PDT Partners LLC , Niayesh Afshordi - University of Waterloo
This course is aimed at advanced undergraduate and beginning graduate students, and is inspired by a book by the same title, written by Padmanabhan. Each session consists of solving one or two pre-determined problems, which is done by a randomly picked student. While the problems introduce various…

Measurement Pattern Interpolation: Theory, and potential applications
Niel de Beaudrap - Institute for Quantum Computing (IQC)
Quantum computation by single-qubit measurements was proposed by Raussendorf and Briegel [PRL 86, 5188] as a potential scheme for implementing quantum computers. It also offers an unusual means of describing unitary transformations. To better understand which measurement-based procedures perform…

What is a Wavefunction?
Garnet Ord - Toronto Metropolitan University
Conventional quantum mechanics answers this question by specifying the required mathematical properties of wavefunctions and invoking the Born postulate. The ontological question remains unanswered. There is one exception to this. A variation of the Feynman chessboard model allows a classical…
Who Is The Inflaton?
Robert Brout - Université Libre de Bruxelles
It is argued that space-time is discretized on the basis of the gravitational interactions among the degrees of freedom of quantum fields.Configurations of fields fall into 2 classes,propagating (cisplanckian in length scale) and those that are transplanckian, sequestered in the space-time that is…
