Ultracold YbAg molecules have been recently proposed as promising candidates for electron electric dipole moment searches Verma et al (2020 Phys. Rev. Lett. 125 153201). Here, we calculate potential energy curves, permanent electric dipole and quadrupole

Observation of pendular butterfly Rydberg molecules
Rydberg molecules have potential for ultracold chemistry applications in light of their unconventional binding mechanism that provides high tunability. Here the authors observe and control butterfly Rydberg molecules, which are bound by a shape resonance

Ultracold chemistry with alkali-metal–rare-earth molecules
A first principles study of the dynamics of $^6$Li($^{2}$S) + $^6$Li$^{174}$Yb($^2 ^+$)$ \to ^6$Li$_2(^1 ^+$) + $^{174}$Yb($^1$S) reaction is presented at cold and ultracold temperatures. The computations involve determination and analytic fitting of a three-dimensional potential energy surface for the Li$_2$Yb system and quantum dynamics ...

Effect of nuclear spin symmetry in cold and ultracold reactions: D + para/ortho-H2
We report results for reaction and vibrational quenching of the collision D with para-H _2 ( $v,j=0$ ) and ortho-H _2 ( $v,j=1$ ) at cold and ultracold temperatures.

Buffer gas cooling of ions in radio-frequency traps using ultracold atoms
Reaching ultracold temperatures within hybrid atom–ion systems is a major limiting factor for control and exploration of the atom–ion interaction in the quantum regime.

Universality and chaoticity in ultracold K+KRb chemical reactions
Studying chemical reactions near zero temperature in detail is challenging both in theory and practice. Here the authors report an explicit quantum mechanical study of the benchmark ultracold reaction between a K atom and a KRb molecule, important for ...

Controlling the nature of a charged impurity in a bath of Feshbach dimers
We theoretically study the dynamics of a trapped ion that is immersed in an ultracold gas of weakly bound atomic dimers created by a Feshbach resonance.

Few-Body Analog Quantum Simulation with Rydberg-Dressed Atoms in Optical Lattices
Most experiments with ultracold atoms in optical lattices have contact interactions and therefore operate at high densities of around one atom per site to observe the effect of strong interactions.

Universal model for exoergic bimolecular reactions and inelastic processes
From a rigorous multichannel quantum-defect formulation of bimolecular processes, we derive a fully quantal and analytic model for the total rate of exoergic bimolecular reactions and/or inelastic processes that is applicable over a wide range of ...
