Correspondence Principle for Many-Body Scars in Ultracold Rydberg Atoms

Physical Review X, 2021
The theory of quantum scarring—a remarkable violation of quantum unique ergodicity—rests on two complementary pillars: the existence of unstable classical periodic orbits and the so-called quasimodes, i.e., the nonergodic states that strongly overlap ...

Drone Delivery Packing Problem on a Neutral‐Atom Quantum Computer

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.
This research models the Drone Delivery Packing Problem as a battery‐constrained graph partitioning. We use Pasqal's Fresnel QPU to sample time‐feasible single‐drone schedules, with tunable delivery targets via hardware parameters, and enforce battery limits by greedy post‐processing.

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.

Dissecting the Electronic Factors Governing Phosphine Oxide Reduction With Silanes: A Computational Study

European Journal of Inorganic Chemistry, Volume 29, Issue 24, 21 August 2026.
Phosphine oxide reduction with silanes is governed by phosphine oxide distortion and silane interaction energies. In R3SiH silanes, NBO analysis reveals that n(O)→σ*(SiR) donation is distributed among several acceptor orbitals, whereas in Ph2RSiH silanes, small electronegative substituents directly bonded to silicon (RCl, OCN, OH) enhance the σ ...

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

Chemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Orientation‐Engineered PtTe2 Schottky FETs: Quantum Transport Insights for Dopant‐Free Advanced Technology Nodes

Advanced Electronic Materials, Volume 12, Issue 16, 24 August 2026.
Monolayer PtTe2 enables dopant‐free Schottky FETs through its thickness‐dependent electronic transition. Quantum transport simulations show that crystallographic orientation strongly influences device performance, with Γ–M transport delivering higher drive current, lower leakage, and improved switching behavior.
