Prof. Kevin H. Knuth and former Ph.D. student Newshaw Bahreyni published a new article on a foundational theory of emergent space-time titled "A Potential Foundation for Emergent Space-Time"
In the article, they present a novel derivation of both the Minkowski metric and Lorentz transformations from the consistent quantification of a causally ordered set of events with respect to an embedded observer. These results suggest that space-time need not be physical, but instead the mathematics of space and time may emerge as the unique way in which an observer can consistently quantify events and their relationships to one another. The result is a potential foundation for emergent space-time. The article is published in the Journal of Mathematical Physics can be found there as well as in the Physics arXiv.
Prof. Kevin H. Knuth, former Ph.D. students Ben Placek and Nabin Malakar, and current Ph.D. student Asim Mubeen, along with their colleague Dr. Michael Habeck, have published a new article on Bayesian Evidence and Model Testing
In this paper, the authors review the concepts of Bayesian evidence and Bayes factors, and their application to model selection. The theory is presented along with a discussion of analytic, approximate and numerical techniques, which are demonstrated through four concrete examples in the areas of brain-computer interface (BCI), sensor characterization in robotics, exoplanet exploration using EXONEST, and molecular force characterization. The article is published in Digital Signal Processing and can be found there or in the physics arXiv.
Prof. Kevin H. Knuth and former UAlbany PostDoc Deniz Gencaga, along with their colleague Prof. William Rossow, published a new article on quantifying information flow in a complex system titled "A Recipe for the Estimation of Information Flow in a Dynamical System"
In the paper, the authors demonstrate the utility of transfer entropy (TE) for computing the information flow in a complex dynamical system. The article, which was published in the journal Entropy, can be found here.
Prof. Goyal publishes new article "Derivation of Quantum Theory from Feynman's Rules"
Building on his previous work showing how to derive Feynman's rules from simpler assumptions, Prof. Goyal's recent article now shows how to derive the rest of the standard von Neumann quantum formalism starting from Feynman's rules, and how to derive the rules for composite systems. The full article is available here.
New Results on Supersymmetry
Using data collected with the ATLAS detector at the Large Hadron Collider at CERN, SUNY physicists Julian Bouffard, Jesse Ernst, Adam Fischer, Vivek Jain, and collaborator Stefan Guindon, have recently made public results that put tight constraints on the existence of particles predicted by Supersymmetry, a very attractive extension of the Standard Model of Particle Physics.
