Physikalisches Kolloquium

Institut für Physik

16:15 Uhr s.t., HS KPH

Prof. Dr. Frank Saueressig, Radboud University, NL
Fusing the principles of general relativity and quantum mechanics in a consistent theoretical framework still constitutes one of the main open challenges in theoretical physics today. Over the last decades, the gravitational asymptotic safety program has taken significant steps towards achieving this goal. A central virtue, driving the success of the approach, is its conservative nature: the program builds on well-established principles of quantum field theory and extends them in a rather minimalistic way. In this talk, we will review the key developments in the program, building up to its present status. I will also attempt to give an outlook on the challenges that need to still be addressed in the future.

Physikalisches Kolloquium

Institut für Physik

16:15 Uhr s.t., HS KPH

Prof. Dr. Reinhard Noack, Philipps University Marburg
Correlated Electrons from Zero to Infinite Dimensions: Early Days of KOMET 7 in Mainz I will talk about the problems in correlated electron systems that occupied us in the early days of the KOMET 7 research group headed by Peter van Dongen. These problems include quantum impurity problems as well as the dynamical mean field theory (DMFT), i.e., correlated electrons in the infinite-dimensional limit. At first glance, these two problems are very different because the impurity problem is in a sense zero-dimensional, whereas the DMFT is formally infinite-dimensional. However, the effective problems and solution methods of these two problems are closely related, and both approaches can be used to describe the behavior of real three-dimensional materials. In addition, a major activity of group members has been to develop and use matrix-product-state and tensor-network methods, especially the density matrix renormalization group. These methods are ideally suited to study quasi-one-dimensional and two-dimensional strongly correlated systems. They can be applied to a variety of systems ranging from transition-metal coumpounds such as the cuprates to organometallic materials such as Bechgaard salts as well as to quantum simulators formed from cold atomic gases on optical lattices.

Theorie-Palaver

Institut für Physik

14:00 Uhr s.t., Lorentz room (Staudingerweg 7, 5th floor)

Jordy de Vries, Amsterdam U., Nikhef
The fact that neutrinos are massive particles can be neatly explained by the existence of (at least two) additional neutrinos, called sterile neutrinos. Depending on their mass, sterile neutrinos can be looked for in various experiments. I will discuss how sterile neutrinos can be probed indirectly in neutrinoless double beta decay experiments and how this search compares to more direct probes and how it can test low-scale leptogenesis as a solution for the baryon number asymmetry of the universe.
