Die Zeitentwicklung isolierter Systeme ist auf kleinsten Skalen durch die Gesetze der Quantenmechanik bestimmt und kann sehr …

On the fundamental level, quantum fluctuations or entanglement lead to complex dynamical behaviour in many-body systems for which a …

The dynamics of quantum systems far from equilibrium represents one of the most challenging problems in theoretical many-body physics. …

To access the dynamics and internal degrees of freedom in a spin-1 system we present experimental implementation schemes for initial …

In this thesis we study long-time spin dynamics in the F = 1 hyperfine manifold of a 87Rb Bose-Einstein condensate (BEC). The magnetic …

When particles in a quantum mechanical system are entangled, a measurement performed on one part of the system can affect the results …

We experimentally study a nonlinear detection scheme in which entangling interactions are time reversed. In this way, nonclassical …

Accessing the connection between classical chaos and quantum many-body systems has been a long-standing experimental challenge. Here, …

High power lasers play an important role in atomic physics, where laser cooling is required. One possibility to achieve high laser …

In this thesis, we study the structure formation following a quench of the detuning of spin exchange. For this, we employ an effective …

In this thesis, we study a novel method to extract the Fisher information of quantum states from direct measurements without the need …

We report on the experimental observation of scaling in the time evolution following a sudden quench into the vicinity of a quantum …

The dynamical evolution of spatial patterns in a complex system can reveal the underlying structure and stability of stationary states. …

We demonstrate experimentally an alternative method for the dynamic generation of atomic spin squeezing, building on the interplay …

The observation of many quantum effects in a spinor Bose gas rely on the possibility for detection at the single-atom level. In a …
