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.

Amorphous materials (glasses) probably constitute >90% of the solid matter surrounding us in everyday life,yet traditional textbooks of condensed matter physics devote virtually no space to them.Crudely speaking,the puzzles in the behavior of glasses can be divided into three major areas:the glass transition itself,the characteristic long-term memory effects and the near-equilibrium thermal,dielectric and transport properties;this talk focusses entirely on the third area.Over the last 40 years it has become apparent that the thermal and transport properties are not only qualitatively universal between glasses with totally different chemistry and microstructure,but in some cases possess a truly mind-boggling degree of _quantitative_ universality.In this talk I will describe the salient experimental data,review the established ("tunnelling two-level system") model commonly used to interpret them,and introduce a rather different scenario (developed in collaboration with D.C.Vural) which holds out some prospect of explaining the universalities in a natural way.

A simple physical realization of an integer quantum Hall state of interacting two dimensional bosons is provided. This is an example of a "symmetry-protected topological" (SPT) phase which is a generalization of the concept of topological insulators to systems of interacting bosons or fermions. Universal physical properties of the boson integer quantum Hall state are described and shown to correspond to those expected from general classifications of SPT phases.
