Effect of thermal fluctuations in topological p-wave superconductors

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.

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.

The Higgs Boson and speculative particle physics

PIRSA:12090065

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.

The LHC detectors are allowing experimentalists to look "inside" of jets and study the properties of these. Jet substructure gives us the tools to study boosted resonances that decay into jets. In this talk, I will discuss an extension of substructure techniques to beyond the Standard Model signals where reconstructing resonances may not be optimal, but these techniques still allow us to pick out these signals from a busy QCD environment.

General Relativity & Quantum Cosmology
The idea that the graviton may be massive has seen a resurgence of interest due to recent progress which has overcome its traditional problems. I will review this recent progress, which has led to a consistent ghost-free effective field theory of a massive graviton, with a stable hierarchy between the graviton mass and the cutoff, and how this theory has the potential to resolve the naturalness problem of the cosmological constant.
