The Entropy of Hawking Radiation—Juan MALDACENA

Black holes have a temperature and an associated entropy. This thermodynamic entropy is equal to the area of their horizon. Surprisingly, black holes have a second entropy, a von Neuman ...

Twisted Topological Tangles or: the knot theory of knitting—Elisabetta MATSUMOTO

Imagine a 1D curve, then use it to fill a 2D manifold that covers an arbitrary 3D object – this computationally intensive materials challenge has been realized in the ancient technology ...

The Origins of Planetary System Architectures—Phil ARMITAGE

Searches for extrasolar planets have shown that planetary systems are not just common, but that they exhibit a broad and mostly unanticipated diversity of architectures. In this talk I will ...

High-energy quantum physics with extremely intense laser pulses—Christoph KEITEL

The field of laser-matter interaction traditionally deals with the response of atoms, molecules, and plasmas to an external light wave. However, the recent sustained technological progress is opening up the ...

Deep learning and proteins—Lucy COLWELL

A central challenge is to be able to predict functional properties of a protein from its sequence, and thus (i) discover new proteins with specific functionality and (ii) better understand ...

Geometric modelling of tangled structures—Myfanwy EVANS

Abstract:

This talk will introduce the use of geometric ideas in the characterisation and analysis of tangled biophysical systems. It will introduce the construction of idealised tangled structures using ideas ...

Bootstrapping Cosmological Correlations—Daniel BAUMANN

Cosmology is famously an observational rather than an experimental science. No experimentalists were present in the early universe, and the birth and subsequent evolution of the universe cannot be repeated ...

The First Stars, Black Holes, and Galaxies in the Universe—John WISE

Cosmic structure forms hierarchically through smooth accretion and dark matter halo mergers. As a consequence, all galaxies are the product of the dozens of mergers over billions of years. However ...

Correlation functions in fully developed turbulence—Leonie CANET

Turbulence is an ubiquitous phenomenon in fluid flows. Yet, calculating its statistical properties, and in particular what is generically called intermittency effects, remains an open issue. In this talk, I ...

Physics Beyond Colliders—Joerg JAECKEL

Abstract:

Particle physics is often equated with high energy collider experiments. However, over recent years it has become increasingly clear that high intensity and high precision experiments offer significant, complementary ...
