Many-body theory for systems with particle conversion: Extending the multiconfigurational time-dependent Hartree method
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
We derive a multiconfigurational time-dependent Hartree theory for systems with particle conversion. In such systems particles of one kind can convert to another kind and the total…

On interacting fermions and bosons with definite total momentum
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
Any {\it exact} eigenstate with a definite momentum of a many-body Hamiltonian can be written as an integral over a {\it symmetry-broken} function . For two particles, we solve…
