Manifold learning of Poincaré sections reveals the topology of high-dimensional chaotic flows
Evangelos Siminos
It is shown that applying manifold learning techniques to Poincaré sections of high-dimensional, chaotic dynamical systems can uncover their low-dimensional topological organizatio…
Effects of oblique incidence and colliding pulses on laser-driven proton acceleration from relativistically transparent ultrathin targets
Julien Ferri, Evangelos Siminos, Laurent Gremillet +1
The use of ultrathin solid foils offers optimal conditions for accelerating protons from laser-matter interactions. When the target is thin enough that relativistic self-induced tr…
Collisional effects on the electrostatic shock dynamics in thin-foil targets driven by an ultraintense short pulse laser
Andréas Sundström, Laurent Gremillet, Evangelos Siminos +1
We numerically investigate the impact of Coulomb collisions on the ion dynamics in high-, solid density caesium hydride and copper targets, irradiated by high-intensity ($I\appr…
Fast collisional electron heating and relaxation in thin foils driven by a circularly polarized ultraintense short-pulse laser
Andréas Sundström, Laurent Gremillet, Evangelos Siminos +1
The creation of well-thermalized, hot and dense plasmas is attractive for warm dense matter studies. We investigate collisionally induced energy absorption of an ultraintense and u…
Enhancement of laser-driven ion acceleration in non-periodic nanostructured targets
I. Thiele, J. Ferri, E. Siminos +6
Using particle-in-cell simulations, we demonstrate an improvement of the target normal sheath acceleration (TNSA) of protons in non-periodically nanostructured targets with micron-…
Laser wakefield driven generation of isolated CEP-tunable intense sub-cycle pulses
Evangelos Siminos, Illia Thiele, Christoffer Olofsson
Sources of intense, ultra-short electromagnetic pulses enable applications such as attosecond pulse generation, control of electron motion in solids and the observation of reaction…
