Like TV ballroom dancing, the Eurovision Song Contest survived ridicule by becoming ridiculous. However, it has thrown up some talented winners. Remember Diggi-loo Diggi-Ley by Herreys?
France Gall was French but won in 1965 when representing Luxembourg. This track wasn't her winning effort but is superior and has a great video, 20 years before MTV. It was written by Serge Gainsbourg, last week's Song of the Week artist.
We study an infinite family of Massive Type IIA backgrounds that holographically describe the twisted compactification of N=(1,0) six-dimensional SCFTs to four dimensions. The analysis of the branes involved suggests a four dimensional linear quiver QFT, that deconstructs the theory in six dimensions. For the case in which the system reaches a strongly coupled fixed point, we calculate some observables that we compare with holographic results. Two quantities measuring the number of degrees of freedom for the flow across dimensions are studied.
In this talk I will present an exclusion process with different types of particles: A, B and C. This last type can be understood as holes. Two scaling limits will be discussed: hydrodynamic limits in the boundary driven setting; and equilibrium fluctuations for an evolution on the torus. In the later case, we distinguish several cases, that depend on the choice of the jump rates, for which we get in the limit either the stochastic Burgers equation or the Ornstein-Uhlenbeck equation. These results match with predictions from non-linear fluctuating hydrodynamics.
