Quantum Many-Body Physics

Systems composed of multiple quantum components exhibit rich physical phenomena and can give rise to the most interesting macroscopic properties (e.g. high-temperature superconductivity or thermalization). Most such systems are very hard to solve, and it is of fundamental interest to develop techniques that allow us a better understanding of these phenomena.

The Theory Division investigates these problems from different perspectives:

Tensor network theory.—Tensor Networks offer the possibility to construct states where collective properties are determined from small local tensors. more
