TL;DR: Relativistic three-dimensional particle-in-cell simulations predict that irradiation of nanostructures at intensities of >1 × 1022 W cm−2 will lead to a virtually unexplored extreme UHED plasma regime characterized by energy densities in excess of 8 × 1010 J cm−3, equivalent to a pressure of 0.35 Tbar.

Challenges of x-ray spectroscopy in investigations of matter under extreme conditions
TL;DR: The role of X-ray spectroscopy in the investigation of radiative properties of strongly coupled, highly correlated, and frequently weakly emissive plasma systems formed in matter irradiated by sub-petawatt and petawatt class lasers is discussed in this paper.

Ionization potential depression in an atomic-solid-plasma picture
Frank B. Rosmej,Frank B. Rosmej +1 more
TL;DR: In this article, an atomic-solid-plasma (ASP) model was developed that permits ionization potential depression studies also for single and multiple core hole states, which is in good agreement with recent quantum molecular dynamics simulations.

The first data from the Orion laser; measurements of the spectrum of hot, dense aluminum
Matthew Hill,P. Allan,Colin D. Brown,James S. Harris,David Hoarty,L. M. R. Hobbs,Steven James,John J. L. Morton,Ed Marley,Ronnie Shepherd,James Dunn,J. Emig,Steve Fulkerson,Hui Chen,Peter Beiersdorfer +14 more
TL;DR: In this article, the Orion laser system was used to study dense plasmas created by a combination of short pulse laser heating and compression by laser driven shocks, and the results indicated that the Ecker and Kroll model overestimates substantially the ionization potential depression in this regime.

Ignition and high gain with ultrapowerful lasers

TL;DR: In this article, a capsule is imploded as in the conventional approach to inertial fusion to assemble a high density fuel configuration, and a hole is bored through the capsule corona composed of ablated material, as the critical density is pushed close to the high density core of the capsule by the ponderomotive force associated with high intensity laser light.

TL;DR: The results are found to disagree with the predictions of the extensively used Stewart-Pyatt model, but are consistent with the earlier model of Ecker and Kröll, which predicts significantly greater depression of the ionization potential.

TL;DR: The experimental data are in closer agreement with simulations using the model of Stewart and Pyatt and an alternative due to Ecker and Kröll suggested by recent x-ray free-electron laser experiments is suggested.

TL;DR: In this article, the authors observed bunches of electrons up to 200 MeV, accelerated in the wakefield of the laser pulse, emitting very energetic Bremsstrahlung photons which were diagnosed directly with photoconductors and indirectly through photonuclear activation measurements.
