Understanding in detail the properties of protons and neutrons, two of the basic building blocks of the visible Universe, has been a long-standing goal for nuclear physics. The strong nuclear force binds together quarks and gluons into protons, neutrons and other hadrons, but the nonlinear, strongly-coupled nature of the strong force makes calculations of hadron properties very challenging. Recent theoretical developments mean calculations of the internal structure of hadrons, using lattice quantum chromodynamics (QCD), have now become possible. Recent proof-of-principle calculations of generalised parton distributions, which encode the three-dimensional structure of hadrons, marked the advent of a new era in lattice QCD calculations. I introduce the ideas that underpin these developments and summarise some of the most exciting recent results.

Abstract: I will talk about the shock formation problem for 1D Burgers equation in the presence of small viscosity. Although the vanishing viscosity problem till moments before the first shock and in presence of a fully developed shocks is very classical, little is known about the moment of shock formation. We develop a matched asymptotic expansion to describe the solution to the viscous Burgers equation (with small viscosity) to arbitrary order up to the first singularity time. The main feature of the work is the inner expansion that accommodates the viscous effects close to the shock location and match it to the usual outer expansion (in viscosity). We do not use the Cole-Hopf transform and hence we believe that this approach works for more general scalar 1D conservation laws. Time permitting, I will talk about generalizing to vanishing viscosity limit from compressible Navier–Stokes to compressible Euler equations. This is joint work with Cole Graham (Brown university).

The high densities achieved in neutron stars and the high densities and temperatures achieved in neutron-star mergers create ideal testing grounds in which to learn about exotic matter, namely hyperons and deconfined quarks. The presence of exotic matter can strongly affect the interior of neutron stars, but cannot be directly observed. New electromagnetic and gravitational-wave constraints have been slowly constraining the dense QCD equation of state, allowing us to learn important information about the strong interaction. Nevertheless, strong constraints on dense and hot matter depend on (a) the not yet observed post-merger period of gravitational-wave production from neutron-star mergers and (b) non-trivial comparisons with particle collision experimental data. In this talk, I discuss where we stand and what we expect to learn about dense matter in the near future.
