A generalization of Kochen-Specker sets

PIRSA:12090073

I will discuss two generalizations of Kochen-Specker (KS) sets: projective KS sets and generalized KS sets. We will see that projective KS sets can be used to characterize all graphs for which the chromatic number is strictly larger than the quantum chromatic number. Here, the quantum chromatic number is defined via a nonlocal game based on graph coloring. We will further show that from any graph with separation between these two quantities, one can construct a classical channel for which entanglement assistance increases the one-shot zero-error capacity. As an example, we will consider a new family of classical channels with an exponential increase.

We shall follow the growth of probability theory and applications from the 1650s onwards, in parallel with the development of statistical inference. Bayesian, Neyman-Pearson hypothesis testing and Fisherian likelihood methods will all be covered, with an emphasis on relating theory to a wide range of applications. Practical sessions will use SciPy and feature closed-form solutions, iterative and Monte Carlo simulation methods.

Condensed Matter

In this talk, I will present our recent work on the effect of thermal fluctuations on the topological stability of chiral p-wave superconductors. We consider two models of superconductors: spinless and spinful with a focus on topological properties and Majorana zero-energy modes. We show that proliferation of vortex-antivortex pairs above the Kosterlitz-Thouless temperature T_KT drives the transition from a thermal Quantum Hall insulator to a thermal metal/insulator, and dramatically modifies the ground-state degeneracy splitting. This shows that in order to utilize 2D chiral p-wave superconductors for topological quantum computing, the temperature should be much smaller than T_KT. Within the spinful chiral p-wave model, we also investigate the interplay between half-quantum vortices carrying Majorana zero-energy modes and full-quantum vortices having trivial topological charge, and discuss topological properties of half-quantum vortices in the background of proliferating full-quantum vortices.

The Higgs Boson and speculative particle physics

The crucial role that the Higgs boson plays in the standard model for strong weak and electromagnetic interactions is reviewed. Recently a resonance with properties consistent with those expected for the Higgs boson has been discovered at the large hadron collider (LHC). This discovery constrains speculations about new physics beyond what is in the standard model. The motivation for such new physics, at roughly the energy scale probed by LHC experiments, and the nature of the constraints imposed by the recent LHC results are discussed.
