Dissipative dynamics of atomic and molecular Rydberg gases: Avalanche to ultracold plasma states of strong coupling
M. Aghigh, K. Grant, R. Haenel +8
Not long after metastable xenon was photoionized in a magneto-optical trap, groups in Europe and North America found that similar states of ionized gas evolved spontaneously from s…
Proof of concept for an optogalvanic gas sensor for NO based on Rydberg excitations
Johannes Schmidt, Markus Fiedler, Ralf Albrecht +9
We demonstrate the applicability of 2-photon Rydberg excitations of nitric oxide (NO) at room temperature in a gas mixture with helium (He) as an optogalvanic gas sensor. The charg…
Arrested relaxation in an isolated molecular ultracold plasma
R. Haenel, M. Schulz-Weiling, J. Sous +5
Spontaneous avalanche to plasma splits the core of an ellipsoidal Rydberg gas of nitric oxide. Ambipolar expansion first quenches the electron temperature of this core plasma. Then…
On the formation and decay of a molecular ultracold plasma
N. Saquet, J. P. Morrison, M. Schulz-Weiling +4
Double-resonant photoexcitation of nitric oxide in a molecular beam creates a dense ensemble of Rydberg states, which evolves to form a plasma of free electrons trapped in…
Charge, density and electron temperature in a molecular ultracold plasma
C. J. Rennick, J. P. Morrison, J. Ortega-Arroyo +3
A Rydberg gas of NO entrained in a supersonic molecular beam releases electrons as it evolves to form an ultracold plasma. The size of this signal, compared with that extracted by…
The very slow expansion of an ultracold plasma formed in a seeded supersonic molecular beam of NO
J. P. Morrison, C. J. Rennick, E. R. Grant
The double-resonant laser excitation of nitric oxide, cooled to 1 K in a seeded supersonic molecular beam, yields a gas of molecules cm in a single selected…
Evolution from a molecular Rydberg gas to an ultracold plasma in a seeded supersonic expansion of NO
J. P. Morrison, C. J. Rennick, J. S. Keller +1
We report the spontaneous formation of a plasma from a gas of cold Rydberg molecules. Double-resonant laser excitation promotes nitric oxide, cooled to 1 K in a seeded supersonic m…
