Theory of exciton-electron scattering in atomically thin semiconductors
Christian Fey, Peter Schmelcher, Atac Imamoglu +1
The realization of mixtures of excitons and charge carriers in van-der-Waals materials presents a new frontier for the study of the many-body physics of strongly interacting Bose-F…
Triatomic butterfly molecules
Matthew T. Eiles, Christian Fey, Frederic Hummel +1
We detail the rich electronic and vibrational structure of triatomic "butterfly" molecules, ultra-long-range Rydberg molecules bound by resonant -wave scattering. We divide thes…
Ultralong-range Rydberg molecules
Christian Fey, Frederic Hummel, Peter Schmelcher
We review ultralong-range Rydberg molecules (ULRM), which are bound states between a Rydberg atom and one or more ground-state atoms with bond lengths on the order of thousands of…
Precision spectroscopy of negative-ion resonances in ultralong-range Rydberg molecules
Felix Engel, Thomas Dieterle, Frederic Hummel +5
The level structure of negative-ions near the electron detachment limit dictates the low-energy scattering of an electron with the parent neutral atom. We demonstrate that a single…
Particle pair creation by inflation of quantum vacuum fluctuations in an ion trap
Matthias Wittemer, Frederick Hakelberg, Philip Kiefer +5
The creation of matter and structure in our universe is currently described by an intricate interplay of quantum field theory and general relativity. Signatures of this process dur…
Observation of spin-orbit-dependent electron scattering using long-range Rydberg molecules
Markus Deiß, Shinsuke Haze, Joschka Wolf +6
We present experimental evidence for spin-orbit interaction of an electron as it scatters from a neutral atom. The scattering process takes place within a Rb ultralong-range Ry…
The building principle of triatomic trilobite Rydberg molecules
Christian Fey, Frederic Hummel, Peter Schmelcher
We investigate triatomic molecules that consist of two ground state atoms and a highly excited Rydberg atom, bound at large internuclear distances of thousands of Ångstroms. In the…
Alignment of s-state Rydberg molecules in magnetic fields
Frederic Hummel, Christian Fey, Peter Schmelcher
We unravel some peculiar properties of ultralong-range Rydberg molecules formed by an -state Rb Rydberg atom and a corresponding ground-state atom whose electronic orbita…
Effective three-body interactions in Cs()-Cs() Rydberg trimers
Christian Fey, Jin Yang, Seth T. Rittenhouse +5
Ultralong-range Rydberg trimer molecules are spectroscopically observed in an ultracold gas of Cs() atoms. The atomic Rydberg state anisotropy allows for the formation of…
Spin-Interaction Effects for Ultralong-range Rydberg Molecules in a Magnetic Field
Frederic Hummel, Christian Fey, Peter Schmelcher
We investigate the fine and spin structure of ultralong-range Rydberg molecules exposed to a homogeneous magnetic field. Each molecule consists of a Rb Rydberg atom whose ou…
Highly excited electronic image states of metallic nanorings
Christian Fey, Henrik Jabusch, Johannes Knörzer +1
We study electronic image states around a metallic nanoring and show that the interplay between the attractive polarization force and a repulsive centrifugal force gives rise to Ry…
Stretching and bending dynamics in triatomic ultralong-range Rydberg molecules
Christian Fey, Markus Kurz, Peter Schmelcher
We investigate polyatomic ultralong-range Rydberg molecules consisting of three ground state atoms bound to a Rydberg atom via - and -wave interactions. By employing the fini…
Control of multiple excited image states around segmented carbon nanotubes
J. Knörzer, C. Fey, H. R. Sadeghpour +1
Electronic image states around segmented carbon nanotubes can be confined and shaped along the nanotube axis by engineering the image potential. We show how several such image stat…
A comparative analysis of binding in ultralong-range Rydberg molecules
Christian Fey, Markus Kurz, Peter Schmelcher +2
We perform a comparative analysis of different computational approaches employed to explore the electronic structure of ultralong-range Rydberg molecules. Employing the Fermi pseud…
Momentum dependence in the dynamically assisted Sauter-Schwinger effect
Christian Fey, Ralf Schützhold
Recently it has been found that the superposition of a strong and slow electric field with a weaker and faster pulse can significantly enhance the probability for non-perturbative…
