Pressure-induced s,p-d electron redistribution accompanies structural transformation in amorphous Zr-Cu alloy under compression
P. Dziegielewski, J. Antonowicz, K. Georgarakis +6
Extreme compression can reorganize atomic valence states, in some regimes driving charge from spatially extended orbitals into more compact ones. We investigate this effect in amor…
Probing the formation of femtosecond laser-induced periodic surface structures on silica films by ultrafast small-angle X-ray scattering
Dominik Kaczmarek, Jean-Luc Déziel, Thies Johannes Albert +16
Ultrashort X-ray pulses, as provided by X-ray Free Electron Lasers (XFELs), offer unique opportunities to probe the formation of laser-induced nanostructures with sizes even below…
Crystallisation kinetics of supercooled liquid palladium
Zuzanna Kostera, Christian Bressler, Przemyslaw Dziegielewski +13
In this study, we employ classical molecular dynamics (MD) simulations to investigate the crystallisation kinetics of supercooled liquid palladium and relate the results to time-re…
Atomic dynamics and local structural disorder during ultrafast melting of polycrystalline Pd
Adam Olczak, Ryszard Sobierajski, Przemyslaw Dziegielewski +8
The primary distinction between solid and liquid phases is mechanical rigidity, with liquids having a disordered atomic structure that allows flow. While melting is a common phase…
Structural pathways for ultrafast melting of optically excited thin polycrystalline Palladium films
Jerzy Antonowicz, Adam Olczak, Klaus Sokolowski-Tinten +28
Due to its extremely short timescale, the non-equilibrium melting of metals is exceptionally difficult to probe experimentally. The knowledge of melting mechanisms is thus based ma…
