    Primordial anisotropies from defects during inflation

    School
    ASTRONOMY

    In this talk we review the imprints of various defects present during inflation on primordial power spectrum. In particular, we look at the effects of a domain wall, a cosmic string, a massive monopole and the vacuum bubble during inflation. We show that these defects generate non-trivial scale-dependent power anisotropies which can be tested from CMB observations ...

    Skew Products and Invariant Graphs

    School
    MATHEMATICS

    This talk concerns the stability and ergodic properties of skew products $T(x, y) =(f(x), g(x, y))$ in which $(f, X, mu)$ is an ergodic map of compact metric space $X$ and $g : X imes Y ightarrow Y$ is continuous. The set $X$ is the base, while $Y$ is the fiber. We consider the case where g is (non-uniformly) contracting. When this contraction is uniform, it can easily be shown that there exists a globally attracting invariant set which is the graph of a function from the base space to the fiber space. Here, we consider the case that the contraction rates are non-uniform and hence specifi ed by Lyapunov exponents and analogous quantities. ...

    Probabilistic Theories of Critical Phenomena, and the Dimer Model

    School
    PARTICLES AND ACCELERATORS

    The probabilistic theories of critical phenomena have been undergoing intense development during the last two decades. Drawing on ideas from statistical physics, many 2D critical lattice models are conjectured or even proved to have conformally invariant scaling limits. We begin by reviewing some fundamental random objects including curves, loop ensembles and surfaces, which arise universally and canonically in these systems, and explain how they are related to many contexts in physics. We then introduce the planar (double-)dimer model as a statistical mechanical model of random 2-dimentional interfaces, and present some results which support ...
