Caroline Robin (Uni Bielefeld and GSI)
Complexity, Entanglement and Quantum Simulations of Nuclear Many-Body Systems

The development of quantum information has provided new perspectives on quantum many-body problems. In nuclear physics, investigations of concepts such as entanglement and non-stabilizerness ("quantum magic") can shed further light on the structure of nuclei and underlying forces. At the same time, the language of quantum information is facilitating communication and exchanges of ideas and techniques between fields of physics. Such cross-fertilization, together with the gained insights, are, in turn, enabling the development of improved methods and algorithms for describing nuclear structure and dynamics on classical and quantum computers. I will discuss some recent developments in these areas.

Theorie-Seminar

Alexander Haber (University of Southampton)
Weak Interactions in Neutron Star Mergers

Weak processes like neutron decay and electron capture play a
fundamental role in the transport properties of neutron stars and their
mergers. In dense nuclear matter, these processes are called direct and
modified Urca processes. In this talk, I will discuss the importance of
flavor equilibration via Urca processes in mergers and present a new,
more accurate, systematically improvable, and consistent approach to
in-medium Urca rates called the "nucleon width approximation". This
novel approach allows us to fundamentally improve the in-medium
calculation of weak decays by taking the interactions of the decaying
nucleons with the medium consistently into account.
