Quantum exchange symmetry induces charge diffusion and trapping in ultracold gases Open
For a homonuclear ion-atom system, we show that the exchange symmetry leads to special outcomes for ion transport that manifest themselves in ultracold experiments. We compute the two body charge hopping probabilities and rates, which are …

Charge Transfer via Temporary Bonds in $C_{60} + C_{60}^+$ Molecular Collisions Open
We present a theoretical description of resonant charge transfer in collisions of nano-particles, specifically for $C_{60} + C_{60}^+$ collisions. We predict that transient bonds between colliding fullerenes can significantly extend the in…

Field Study of Turbulence Intensity measurement by Nacelle Mounted Lidar (NML) Open
In this paper, Nacelle Mounted LiDAR (NML) was used to study Turbulence Intensity (TI) by dataset from three measurement campaigns, using two approaches: the white box test and the black box test. The white box test was to compare TI LOS u…

Ultralong-range molecule engineering via Rydberg dressing Open
In 2000, three pioneering papers launched a new era in Rydberg physics. One predicted the blockade mechanism where extremely large Rydberg-Rydberg interactions only allow a single excitation in a given volume. A second envisioned how stron…

Phase-amplitude formalism for ultranarrow shape resonances Open
We apply Milne's phase-amplitude representation [W. E. Milne, Phys. Rev. 35, 863 (1930)] to a scattering problem involving disjoint classically allowed regions separated by a barrier. Specifically, we develop a formalism employing differen…

Signature of the -Wave Regime High above Ultralow Temperatures Open
Resonant exchange is a general process playing a key role in many-body dynamics and transport phenomena, such as spin, charge, or excitation diffusion. The underlying process is described by the resonant exchange cross section. We show tha…

Signature of the $s$-wave regime high above ultralow temperatures Open
Physical processes involving charge transfer, spin exchange, or excitation exchange often occur in conditions of resonant scattering. We show that the $s$-wave contribution can be used to obtain a good approximation for the full cross sect…
