Supernovae anisotropy power spectrum

School
ASTRONOMY

We contribute another anisotropy study to this field of research using Supernovae Type Ia (SNe Ia). In this work, we utilise the power spectrum calculation method and apply it to both the current SNe Ia data and simulation. Our simulations are constructed with the characteristics of the upcoming supernova surveys like the Large Synoptic Survey Telescope (LSST), which shall bring us the largest SNe Ia collection to date. We make predictions for the amplitude of a possible dipole anisotropy or anisotropy in higher multipole moments that would be detectable by data from future surveys. ...

Impurity bound states in d-wave superconductors with subdominant order parameters

It is well-known that a single magnetic impurity induces bound states inside the energy gap of conventional s-wave superconductors. On the other hand, in d-wave superconductors only virtual bound states with finite lifetime can be induced by potential or/and magnetic impurity. However, in small islands of YBa2Cu3O7-? a fully gapped spectrum has recently been discovered [1, 2] and this fact paves the way to induce real bound states in d-wave superconductors. In this work, we investigate the intra-gap bound states due to potential and magnetic im ...

Non-local Correlations and Fractional Symmetries

School
PARTICLES AND ACCELERATORS

In critical dynamics, non local correlations are observed. Fractional derivatives as operators which gather non-local information have been suggested as possible symmetries of such phenomena. In this talk we first look over some phenomena in nature which have long distance correlations. We then shortly introduce fractional derivatives. In the end we add such derivatives to the Galilean conformal algebras and present a new class of such symmetries.
