Multilevel Monte Carlo simulation of soft matter using coarsegrained models
Soft matter encompasses a wide variety of materials that are composed of mesoscopic particles in solution. The numerical study of such materials is complicated by the difference in lengthscales between an atomistic, ... 
Conformal Properties of Spacetime
We begin by studying a property first introduced by Roger Penrose as a consistency condition for possible constructions of quantum gravity. In an asymptotically flat spacetime, this property, which we call the Penrose ... 
Rayleigh scattering of the Cosmic Microwave Background: Towards a first detection with the next generation of surveys.
The cosmic microwave background (CMB) has been a treasure trove for cosmology. CMB experiments such as Planck have put stringent constraints on the now standard model for Cosmology: ΛCDM. Over the next decade, current and ... 
Bootstrap Techniques in Flat Space and Cosmology
The scientific understanding of the Universe is evolving at a rapid pace. Each new experiment yields more and more accurate measurements of its fundamental parameters. The standard cosmological model postulates a very early ...
