Plasma formation from ultracold Rydberg gases [PDF]

Physical Review A, 2003
Recent experiments have demonstrated the spontaneous evolution of a gas of ultracold Rydberg atoms into an expanding ultracold plasma, as well as the reverse process of plasma recombination into highly excited atomic states. Treating the evolution of the

Gene Expression Alteration by Non-thermal Plasma-Activated Media Treatment in Radioresistant Head and Neck Squamous Cell Carcinoma [PDF]

Clinical and Experimental Otorhinolaryngology
Objectives. Head and neck squamous cell carcinoma (HNSCC) exhibits high recurrence rates, particularly in cases of radioresistant HNSCC (RR-HNSCC). Non-thermal plasma (NTP) therapy effectively suppresses the progression of HNSCC. However, the therapeutic

Propagation of ultra-short, resonant, ionizing laser pulses in rubidium vapor [PDF]

, 2019
We investigate the propagation of ultra-short laser pulses in atomic rubidium vapor. The pulses are intensive enough to ionize the atoms and are directly resonant with the 780 nm $D_2$ line.
