A New Method and a New Scaling For Deriving Fermionic Mean-field Dynamics
Sören Petrat, Peter Pickl
We introduce a new method for deriving the time-dependent Hartree or Hartree-Fock equations as an effective mean-field dynamics from the microscopic Schroedinger equation for fermi…
Derivation of Mean-field Dynamics for Fermions
Sören Petrat
In this work, we derive the time-dependent Hartree(-Fock) equations as an effective dynamics for fermionic many-particle systems. Our main results are the first for a quantum mecha…
Effective dynamics of a tracer particle in a dense homogeneous quantum gas
M. Jeblick, D. Mitrouskas, S. Petrat +1
We investigate the mean field regime of the dynamics of a tracer particle in a homogenous quantum gas. For a bosonic gas, we show that this regime is constrained by the well known…
Multi-Time Formulation of Pair Creation
Sören Petrat, Roderich Tumulka
In a recent work [8], we have described a formulation of a model quantum field theory in terms of a multi-time wave function and proposed a suitable system of multi-time Schroeding…
