Radio frequency field-induced electron mobility in an ultracold plasma state of arrested relaxation
R. Wang, M. Aghigh, K. L. Marroquín +5
Penning ionization releases electrons in a state-selected Rydberg gas of nitric oxide entrained in a supersonic molecular beam. Subsequent processes of electron impact avalanche, b…
Coupled rate-equation hydrodynamic simulation of a Rydberg gas Gaussian ellipsoid: Classical avalanche and evolution to molecular plasma
Rafael Haenel, Edward Grant
An ellipsoidal volume of Rydberg molecules, entrained in a supersonic molecular beam, evolves on a nanosecond timescale to form a strongly coupled ultracold plasma. We present coup…
Control of molecular ultracold plasma relaxation dynamics by mm-wave Rydberg-Rydberg transitions
Fernanda Banic Viana Martins, James S. Keller, Edward R. Grant
Resonant mm-wave fields drive transitions in a state-selected Rydberg gas of NO. This transformation produces a clear signature in t…
Palatini frames in scalar-tensor theories of gravity
Aleksander Kozak, Andrzej Borowiec
A new systematic approach extending the notion of frames to the Palatini scalar-tensor theories of gravity in various dimensions n>2 is proposed. We impose frame transformation ind…
