Energy Landscapes in Chemical Reactions and Transport
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Binding potentials and interaction gates between microwave-dressed Rydberg atoms
, 2014 We demonstrate finite range binding potentials between pairs of Rydberg atoms interacting with each other via attractive and repulsive van der Waals potentials and driven by a microwave field.

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems
Laser &Photonics Reviews, EarlyView.This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

Exploring the vibrational series of pure trilobite Rydberg molecules
Nature Communications, 2023 In trilobite Rydberg molecules, an atom in the ground state is bound by electron-atom scattering to a Rydberg electron that is in a superposition of high angular momentum states.

Blinking Optical Tweezers for Atom Rearrangements
Advanced Quantum Technologies, EarlyView.The work introduces an energy‐efficient method for holding and rearranging an N ×$\times$ M array of atoms using only N optical tweezers, using just 1M of the optical power per atom. In the proof‐of‐concept experiments, single blinking tweezer holds M = 9 atoms and further facilitates rearrangement M = 4 ∼$\sim$ 5 atoms in various configurations ...

Entanglement Swapping for Partially Entangled Qudits and the Role of Quantum Complementarity
Advanced Quantum Technologies, EarlyView.The entanglement swapping protocol is extended to partially entangled qudit states and analyzed through complete complementarity relations. Analytical bounds on the average distributed entanglement are established, showing how the initial local predictability and entanglement constrain the operational distribution.
