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…
