A ground state atom immersed in the wave function of the valence electron of a Rydberg atom can generate a long-range Rydberg molecule (LRRM). In this work, using the multipole expansion of the electrostatic interaction in prolate spheroidal coordinates, approximate and compact expressions of the electrostatic potential that determine the chemistry of trilobite and butterfly LRRM are explored. It is shown that even the prolate spheroidal monopole term can be used to describe general features of… 


Electrically dressed ultra-long-range polar Rydberg molecules
We investigate the impact of an electric field on the structure of ultralong-range polar diatomic Rydberg molecules. Both the s-wave and p-wave interactions of the Rydberg electron and the neutral
Hamiltonian for the inclusion of spin effects in long-range Rydberg molecules
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 ultracold
Ultra-long-range Rydberg trimers with a repulsive two-body interaction.
It is shown that by adding a second ground-state atom, a long-range bound triatomic molecule becomes possible.
Creation of polar and nonpolar ultra-long-range rydberg molecules
A ubiquitous class of long-range molecular Rydberg states, whose Born-Oppenheimer potential curves are oscillatory in nature are predicted, whose oscillations reflect the nodal structure of the atomic Ryd Berg state wave functions.
Alignment of s -state Rydberg molecules in magnetic fields
We unravel some peculiar properties of ultralong-range Rydberg molecules formed by an $s$-state $^{87}$Rb Rydberg atom and a corresponding ground-state atom whose electronic orbitals are spherically
Ultralong-range Rydberg molecules
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 thousands of Bohr radii. The
LETTER TO THE EDITOR: Ultra-long-range Rydberg molecules exposed to a magnetic field
We investigate the impact of an external magnetic field on ultra-long-range and ultracold Rydberg molecules. The Born–Oppenheimer potential surfaces are analysed and discussed for different values of
LETTER TO THE EDITOR: Shape-resonance-induced long-range molecular Rydberg states
When an excited atomic electron interacts with a neutral perturbing atom or molecule that possesses a shape resonance, it generates a characteristic class of Born-Oppenheimer potential curves that
Quantum and semiclassical analysis of long-range Rydberg molecules
A recent study suggests the existence of highly polar and nonpolar long-range Rydberg molecules under temperature and density conditions representative of those found in atomic Bose-Einstein
Anisotropic blockade using pendular long-range Rydberg molecules
We propose an experiment to demonstrate a novel blockade mechanism caused by long-range anisotropic interactions in an ultracold dipolar gas composed of the recently observed "butterfly" Rydberg
