Project B5
In the theory project B5, different non-perturbative numerical methods, based on Krylov-space techniques, self-energy-functional theory and density-matrix renormalization, will be developed and used to study prototypical models of strongly correlated fermions and spins far from equilibrium. Two visionary long-term goals characterize the physical project idea: (i) A comprehensive concept and quantitative theory of “dynamical phase transitions” shall be worked out and applied to study time-dependent Mott metal-insulator and magnetic transitions. (ii) A time-dependent theory of X-ray spectroscopies shall be developed to understand in detail how correlations affect the measured intensities in corresponding pump-probe experiments, in particular close to a dynamical phase transition. We are seeking excellent candidates who are motivated to perform independent research in the fields of many-body theory and non-equilibrium physics in collaboration with different projects in the SFB925. There is an open PhD position, please contact Michael Potthoff for details.
