Ultracold rydberg molecules

JP Shaffer, ST Rittenhouse, HR Sadeghpour - Nature communications, 2018‏ - nature.com
Ultracold molecules formed from association of a single Rydberg atom with surrounding
atoms or molecules and those from double Rydberg excitations are discussed in this review …

Ultralong-range Rydberg molecules

C Fey, F Hummel, P Schmelcher - Molecular Physics, 2020‏ - Taylor & Francis
We review ultralong-range Rydberg molecules (ULRMs), which are bound states between a
Rydberg atom and one or more ground-state atoms with bond lengths on the order of …

Vibronic interactions in trilobite and butterfly Rydberg molecules

F Hummel, P Schmelcher, MT Eiles - Physical Review Research, 2023‏ - APS
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 …

MT Eiles - Journal of Physics B: Atomic, Molecular and Optical …, 2019‏ - iopscience.iop.org
This PhD tutorial discusses ultra-long-range Rydberg molecules, the exotic bound states of
a Rydberg atom and one or more ground state atoms immersed in the Rydberg electron's …

Ultracold chemical reactions of a single Rydberg atom in a dense gas

M Schlagmüller, TC Liebisch, F Engel, KS Kleinbach… - Physical Review X, 2016‏ - APS
Within a dense environment (ρ≈ 10 14 atoms/cm 3) at ultracold temperatures (T< 1 μ K), a
single atom excited to a Rydberg state acts as a reaction center for surrounding neutral …

Precision spectroscopy of negative-ion resonances in ultralong-range Rydberg molecules

F Engel, T Dieterle, F Hummel, C Fey, P Schmelcher… - Physical review …, 2019‏ - APS
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 …

Hamiltonian for the inclusion of spin effects in long-range Rydberg molecules

MT Eiles, CH Greene - Physical Review A, 2017‏ - APS
The interaction between a Rydberg electron and a neutral atom situated inside its extended
orbit is described via contact interactions for each atom-electron scattering channel. In …

Topological edge states in a Rydberg composite

MT Eiles, CW Wächtler, A Eisfeld, JM Rost - Physical Review B, 2024‏ - APS
We examine topological phases and symmetry-protected electronic edge states in the
context of a Rydberg composite: a Rydberg atom interfaced with a structured arrangement of …

Charged ultralong-range Rydberg trimers

DJ Bosworth, F Hummel, P Schmelcher - Physical Review A, 2023‏ - APS
We show that the recently observed class of long-range ion-Rydberg molecules can be
divided into two families of states, which are characterized by their unique electronic …
