Vibronic interactions in trilobite and butterfly Rydberg molecules
Frederic Hummel, Peter Schmelcher, Matthew T. Eiles
Ultralong-range Rydberg molecules provide an exciting testbed for molecular physics at exaggerated scales. In the so-called trilobite and butterfly Rydberg molecules, the Born-Oppe…
Charged ultralong-range Rydberg trimers
Daniel J. Bosworth, Frederic Hummel, Peter Schmelcher
We show that the recently observed class of long-range ion-Rydberg molecules can be divided into two families of states, which are characterised by their unique electronic structur…
Symmetry-induced decoherence-free subspaces
Jonathan Dubois, Ulf Saalmann, Jan Michael Rost
Preservation of coherence is a fundamental yet subtle phenomenon in open systems. We uncover its relation to symmetries respected by the system Hamiltonian and its coupling to the…
Enhanced high-order harmonics through periodicity breaks: from backscattering to impurity states
Chuan Yu, Ulf Saalmann, Jan M. Rost
Backscattering of delocalized electrons has been recently established [Phys. Rev. A 105, L041101 (2022)] as a mechanism to enhance high-order harmonic generation (HHG) in periodic…
