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 …

Mechanisms of antiwear tribofilm growth revealed in situ by single-asperity sliding contacts

NN Gosvami, JA Bares, F Mangolini, AR Konicek… - Science, 2015 - science.org
Zinc dialkyldithiophosphates (ZDDPs) form antiwear tribofilms at sliding interfaces and are
widely used as additives in automotive lubricants. The mechanisms governing the tribofilm …

Atom-based sensing of weak radio frequency electric fields using homodyne readout

From molecular spectra to a density shift in dense Rydberg gases

A Gaj, AT Krupp, JB Balewski, R Löw… - Nature …, 2014 - nature.com
In Rydberg atoms, at least one electron is excited to a state with a high principal quantum
number. In an ultracold environment, this low-energy electron can scatter off a ground state …

Creation of Rydberg polarons in a Bose gas

F Camargo, R Schmidt, JD Whalen, R Ding… - Physical review …, 2018 - APS
We report spectroscopic observation of Rydberg polarons in an atomic Bose gas. Polarons
are created by excitation of Rydberg atoms as impurities in a strontium Bose-Einstein …

Photoassociation of Long-Range Rydberg Molecules

DA Anderson, SA Miller, G Raithel - Physical review letters, 2014 - APS
We observe long-range homonuclear diatomic n D Rydberg molecules photoassociated out
of an ultracold gas of Rb 87 atoms for 34≤ n≤ 40. The measured ground-state binding …

Long-range Rydberg-atom–ion molecules of Rb and Cs

A Duspayev, X Han, MA Viray, L Ma, J Zhao… - Physical Review …, 2021 - APS
We propose a novel type of Rydberg dimer, consisting of a Rydberg-state atom bound to a
distant positive ion. The molecule is formed through long-range electric-multipole interaction …

Experimental characterization of singlet scattering channels in long-range Rydberg molecules

H Saßmannshausen, F Merkt, J Deiglmayr - Physical review letters, 2015 - APS
We observe the formation of long-range Cs 2 Rydberg molecules consisting of a Rydberg
