The search for the most fundamental interactions in Nature probes the shortest distances ever reached. Right now, a major impact comes from the experimental front, in particular from the Large Hadron Collider (LHC) at CERN, but also from neutrino experiments, and, remarkably, from cosmology. In the theoretical particle physics group at the NBIA we explore all these frontiers and have a strong focus on modern amplitude calculations.

This line of research at the NBIA spans a variety of topics in astrophysical fluid- and magnetohydrodynamics and radiative transfer, using a broad range of theoretical techniques and numerical tools. Topics of interest include: accretion flows around young stars and compact objects, the interstellar medium, the intergalactic medium in galaxy clusters, as well as the early evolution of our solar system and exoplanetary systems. We have access to powerful computer resources and interact on a daily basis with the Computational Astrophysics Group at the the NBI.

These are exciting times for neutrino astro-physicists, with the IceCube telescope paving the way for a new neutrino astronomy era. The prime focus of the NBIA neutrino astrophysics group is to shed light on the role of neutrinos in astrophysical environments, such as core-collapse supernovae and gamma-ray bursts, by adopting neutrinos to learn about the source properties. This new group has recently joined ongoing local efforts in astroparticle physics, aiming to place the NBIA at the forefront of an exciting and rapidly developing field.

The research carried out in this field by the group at the NBIA is at the boundary between fundamental physics and astrophysics/cosmology, investigating the origin of the matter-antimatter asymmetry of the universe, the nature of the dark matter (and of dark energy), the generation of the primordial fluctuations which seeded large-scale structure, and the sources and propagation of high energy cosmic radiation - charged particles, gamma-rays and neutrinos.

The condensed matter theory group at the NBIA seeks to understand how to create, control, measure, and protect quantum coherence and entanglement in quantum many-body systems. This is crucial for building large controlled interacting quantum devices, such as solid-state qubits, nanowires and nanotubes. We maintain close links with the Center for Quantum Devices, with many opportunities for theory-experiment collaborations on these fundamental topics.
