Well-controlled synthetic quantum systems, such as ultracold atoms in optical lattices, offer intriguing possibilities to study complex many-body problems in regimes that are beyond reach using state-of-the-art numerical techniques. This enables us, for instance, to shed new light on fundamental questions about the thermalization of isolated quantum many-body systems. Recently, a class of models has been identified that lies in between the extreme limits of thermal and localizing behavior. Here ergodicity-breaking occurs due to an emergent fragmentation of the many-body Hilbert space. A versatile platform that paves the way towards studying these phenomena is the 1D Fermi-Hubbard model with a strong linear potential. [more]

Interactions govern the flow of information and the structure of correlations in quantum systems. Typical interactions decay with distance, resulting in a network of connectivity that is dictated by geometry. Yet a variety of applications, in areas ranging from quantum simulation to combinatorial optimization, demand more versatile control of the graph of interactions. [more]

+++ONLINE COLLOQUIUM+++ How to shrink accelerators and light sources? (Prof. Dr. X. Franz Kärtner)

The use of very high frequencies enables operation of accelerators at higher field strength with lower energetic driver pulses scaling with wavelength cube. Approaches towards a linear terahertz accelerator technology to realize ultrabright and compact electron sources for both ultrafast electron diffraction as well as X-ray sources are discussed. [more]
