Swift charged particles in a degenerate electron gas: An estimation for the Barkas effect in stopping
I. Nagy, I. Aldazabal
Applying a recently suggested new form [Phys. Rev. A {\bf 94}, 042704 (2016)] for the stopping power in terms of scattering phase shifts, here we show analytically that an exact le…

Exact spectral decomposition of a time-dependent one-particle reduced density matrix
I. Nagy, J. Pipek, M. L. Glasser
We determine the exact time-dependent non-idempotent one-particle reduced density matrix and its spectral decomposition for a harmonically confined two-particle correlated one-dime…
