    • Efficient estimation and verification of quantum many-body systems 

      Dissertation
      Holzäpfel, Milan (Universität Ulm, 2019-10-17)
      Quantum systems and tensors share the property that the complexity of their description grows exponentially with the number of physical subsystems or tensor indices. This thesis discusses efficient methods for tensor ...
    • Heat transport in open quantum chains: currents, fluctuations, and rectification 

      Dissertation
      Motz, Thomas (Universität Ulm, 2019-04-18)
      This cumulative thesis addresses the subject of thermal energy transport in quantum systems. Based on an exact stochastic description of the system‘s interaction with its environment, a numerically efficient and flexible ...
    • Numerical simulation of the dynamics and correlations in quantum many body systems 

      Dissertation
      Pichler, Thomas (Universität Ulm, 2016-11-22)
      This thesis discusses the application of numerical methods to different complex quantum systems. I present the successful application of the chopped random basis optimal control algorithm (CRAB) to these systems. This ...
    • Theoretical approach to high-precision atom interferometry 

      Dissertation
      Ufrecht, Christian (Universität Ulm, 2019-08-14)
      The wave properties of matter in quantum mechanics first postulated by de Broglie in 1923 as well as Einstein’s theory of general relativity have radically changed our perception of the world at the beginning of the ...
