Core-Hole Excitation Dynamics of One-Dimensional Ultracold Trapped Fermions
André Becker, Georgios M. Koutentakis, Peter Schmelcher
We investigate the nonequilibrium dynamics of core-hole excitations in a one-dimensional fermionic few-body system consisting of a spin-polarized Fermi bath coupled to a single hea…

Two-Body Kapitza-Dirac Scattering of One-Dimensional Ultracold Atoms
André Becker, Georgios M. Koutentakis, Peter Schmelcher
Kapitza-Dirac scattering, the diffraction of matter waves from a standing light field, is widely utilized in ultracold gases, but its behavior in the strongly interacting regime is…

Dynamical probe of the pseudo Jahn-Teller effect in one-dimensional confined fermions
André Becker, Georgios M. Koutentakis, Peter Schmelcher
We investigate the real-time dynamics of a quenched quantum impurity immersed in a one-dimensional ultracold Fermi gas, focusing on the breakdown of the adiabatic Born-Oppenheimer…
