##Quantum mechanics predicts that electrons in a solid or atoms in a gas can loose their single-particle properties completely and instead start behaving collectively. This often leads to the emergence of new states of matter which are a fascinating topic for fundamental research and offer the potential for technological advances. Important examples include high-temperature superconductivity in cuprates and iron pnictides, quantum wires such as carbon nanotubes, as well as the Bose-Einstein condensation in trapped atomic gases at ultracold temperatures.##

##The research interests of our group lie in the theoretical explanation of the physics of such strongly correlated quantum systems. Recent publications include work on##

• ##Quenches and thermalization,##
  
  
• ##Many-body localization,##
  
  
• ##Entanglement measures,##
  
  
• ##Dynamical quantum phase transitions,##
  
  
• ##transport in spin chains and quantum wires,##
  
  
• ##spin textures in quantum dots,##
  
  
• ##neural networks for many-body systems,##
  
  
• ##multiferroic behavior in spin chains,##
  
  
• ##domain walls in ferromagnetic Luttinger liquids,##
  
  
• ##compounds with orbital degrees of freedom,##
  
  
• ##quantum critical points in magnetic systems with frustration,##
  
  
• ##field- or pressure-driven phase transitions in magnetic systems (Bose-Einstein condensation of magnons).##
  
  

##Our research on these topics often combines analytical methods (Bethe ansatz, bosonization, conformal field theory, nonlinear sigma-models, renormalization group) with numerical methods, in particular, the density-matrix renormalization group (DMRG). We have developed several new DMRG-type algorithms to study quantum dynamics both in equilibrium at finite temperatures and in non-equilibrium following a quantum quench.##
