In this paper, we present ideas that were part of the miniconference on the crossover
between High Energy Density Plasmas (HEDP) and Ultracold Neutral Plasmas (UNPs) at …

Spontaneous avalanche to plasma begins in the core of an ellipsoidal Rydberg gas of nitric
oxide. Ambipolar expansion of NOs to reach an imaging detector. The initial density of …

We argue that the quenched ultracold plasma presents an experimental platform for
studying the quantum many-body physics of disordered systems in the long-time and finite …

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 …

Over the last 20 years there have been a string of exciting discoveries emerging from the
study of highly excited Rydberg atoms resulting in an explosion of activity in Rydberg atom …

We have experimentally demonstrated both heating and cooling of electrons in an ultracold
neutral plasma (UNP) by embedding Rydberg atoms into the plasma soon after its creation …

Penning ionization releases electrons in a state-selected Rydberg gas of nitric oxide
entrained in a supersonic molecular beam. Subsequent processes of electron impact …

The exploration of large-scale many-body phenomena in quantum materials has produced
many important experimental discoveries, including novel states of entanglement, topology …

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 …

We report a time-resolved study on the electron kinetics and dynamics that occur during the
formation of an ultracold plasma generated by resonance enhanced multiphoton ionization …
