Multi-pair states in electron-positron pair creation
Anton Wöllert, Heiko Bauke, Christoph H. Keitel
Ultra strong electromagnetic fields can lead to spontaneous creation of single or multiple electron-positron pairs. A quantum field theoretical treatment of the pair creation proce…
Relativistic tunneling picture of electron-positron pair creation
Anton Wöllert, Michael Klaiber, Heiko Bauke +1
The common tunneling picture of electron-positron pair creation in a strong electric field is generalized to pair creation in combined crossed electric and magnetic fields. This en…
Lanczos algorithm with Matrix Product States for dynamical correlation functions
P. E. Dargel, A. Wöllert, A. Honecker +3
The density-matrix renormalization group (DMRG) algorithm can be adapted to the calculation of dynamical correlation functions in various ways which all represent compromises betwe…
Solitary excitations in one-dimensional spin chains
Anton Wöllert, Andreas Honecker
We study the real-time evolution of solitary excitations in 1-d quantum spin chains using exact diagonalization (ED) and the density-matrix renormalization group (DMRG). The underl…
