A Contract-Grade Verifier for LLM-Generated GPU Kernels, and a Native Blackwell Backward for the Gated-Linear-Recurrence Family
Rishi Shah, Rishav Shrestha
Systems that generate GPU kernels with language models report high correctness rates. Those rates come from a single loose test: run the kernel on a few random inputs at one fixed…
Observation of -symmetry ultralong-range Rydberg molecules
Matthew T. Eiles, Aleksandr Zaitsev, Dominik Dorer +5
We observe weakly-bound -symmetry electronic states in the spectroscopy of Rb+Rb() ultralong-range Rydberg molecules. We detect these molecul…
Universal response of Rydberg manifolds to standing light waves from the microwave to the X-ray regime
Homar Rivera-RodrÃguez, Matthew T. Eiles, Jan M. Rost
Standing light waves structure the electronic density of a Rydberg atom in a rich but surprisingly systematic fashion. We uncover these systematics, which are nearly universal acro…
Microscopic Rydberg electron orbit manipulation with optical tweezers
Homar Rivera-RodrÃguez, Matthew T. Eiles, Tilman Pfau +1
Laser cooling and trapping of atomic matter waves in optical potentials has enabled rapid progress in quantum science, particularly when combined with Rydberg excitation of the ato…
Revealing electron-ytterbium interactions through Rydberg molecular spectroscopy
Tangi Legrand, Xin Wang, Milena SimiÄ +5
Divalent atoms have emerged as powerful alternatives to alkalis in ultracold atom platforms, offering unique advantages arising from their two-electron structure. Among these speci…
Observation of spin singlet butterfly Rydberg molecules in an ultracold atomic Rb gas
Markus Exner, Rohan Srikumar, Richard Blättner +4
We report the observation of spin-singlet ultra-long range Rydberg butterfly molecules consisting of a ground-state atom bound to a Rydberg atom by -wave scattering of Rb…
