Abstract:
An arrangement of particles is said to be "hyperuniform" if its density
fluctuations over large distances are strongly suppressed relative to a
random configuration. Crystals, for example, are hyperuniform. Recently,
several disordered materials have been found to be hyperuniform. Examples
are sheared suspensions and emulsions, and random close packings of hard
spheres. We show that externally driven asymmetric particles in a liquid

Abstract:
The remarkable detection of gravitational waves by the LIGO/Virgo
collaboration has opened a new window into the cosmos. In this
colloquium, we explain how particle theorists can help out with
high-precision calculations relevant for gravitational-wave emission
from compact astrophysical objects. We describe theoretical tools
such as the duality between color and kinematics, double-copy
relations and generalized unitarity. We explain how these ideas can

Abstract:
Optical spectroscopy emerged as a valuable tool to study live biological tissue at various scales and
detect early disease in the human body. While fluorescence and Raman spectra are sensitive to
molecular properties of tissue, light scattering spectra, originating from the extracellular matrix,
subcellular structures, and other tissue inhomogeneities, carry information about tissue microscopic and
macroscopic organization. In this talk we will discuss how scattered light can be used for noninvasive
