Ultrafast Nonthermal Lattice Destabilization and Suppression of Polar Optical Scattering in Electronically Excited -SiO from First-Principles and Deep Neural Network Potential Modeling
Iyyappa Rajan Panneerselvam, Mark Yeung, Charlotte Palmer +2
We present a multiscale first-principles-to-machine-learning approach to investigate ultrafast lattice dynamics in electronically excited -SiO. Ab initio molecular dynamics…
Real-time Electron Solvation Induced by Bursts of Laser-accelerated Protons in Liquid Water
A. Prasselsperger, M. Coughlan, N. Breslin +11
Understanding the mechanisms of proton energy deposition in matter and subsequent damage formation is fundamental to radiation science. Here we exploit the picosecond (10^-12 s) re…
General features of experiments on the dynamics of laser-driven electron-positron beams
J. R. Warwick, A. Alejo, T. Dzelzainis +14
The experimental study of the dynamics of neutral electron-positron beams is an emerging area of research, enabled by the recent results on the generation of this exotic state of m…
Experimental observation of a current-driven instability in a neutral electron-positron beam
J. Warwick, T. Dzelzainis, M. E. Dieckmann +16
We report on the first experimental observation of a current-driven instability developing in a quasi-neutral matter-antimatter beam. Strong magnetic fields ( 1 T) are measur…
Attosecond Control of Relativistic Electron Bunches using Two-Colour Fields
M. Yeung, S. Rykovanov, J. Bierbach +10
Energy coupling during relativistically intense laser-matter interactions is encoded in the attosecond motion of strongly driven electrons at the pre-formed plasma-vacuum boundary.…
Ultrafast opacity in borosilicate glass induced by picosecond bursts of laser-driven ions
B. Dromey, L. Stella, D. Adams +22
Direct investigation of ion-induced dynamics in matter on picosecond (ps, 10-12 s) timescales has been precluded to date by the relatively long nanosecond (ns, 10-9 s) scale ion pu…
Femtosecond-scale Synchronisation of Ultra-Intense Focused Laser Beams
D. J. Corvan, W. Schumaker, J. Cole +10
Synchronising ultra-short (~fs) and focussed laser pulses is a particularly difficult task, as this timescale lies orders of magnitude below the typical range of fast electronic de…
Ultra-high brilliance multi-MeV -ray beam from non-linear Thomson scattering
G. Sarri, D. J. Corvan, W. Schumaker +13
We report on the generation of a narrow divergence ( mrad), multi-MeV ( MeV) and ultra-high brilliance ( photons s m…
Enhanced harmonic generation in relativistic laser plasma interaction
C. Rödel, E. Eckner, J. Bierbach +12
We report the enhancement of individual harmonics generated at a relativistic ultra-steep plasma vacuum interface. Simulations show the harmonic emission to be due to the coupled a…
Relativistic plasma optics enabled by near-critical density nanostructured material
J. H. Bin, W. J. Ma, H. Y. Wang +11
The nonlinear optical properties of a plasma due to the relativistic electron motion in an intense laser field are of fundamental importance for current research and the generation…
Bright subcycle XUV pulse from a single dense relativistic electron sheet
W. J. Ma, J. H. Bin, H. Y. Wang +11
Relativistic electrons are prodigious sources of photons. Beyond classical accelerators, ultra-intense laser interactions are of particular interest as they allow the coherent moti…
Relativistic Frequency Synthesis of Light Fields
C. Rödel, E. Eckner, J. Bierbach +12
Waveform shaping and frequency synthesis based on waveform modulation is ubiquitous in electronics, telecommunication technology, and optics. For optical waveforms, the carrier fre…
Harmonic Generation from Relativistic Plasma Surfaces in Ultra-Steep Plasma Density Gradients
Christian Rödel, Daniel an der Brügge, Jana Bierbach +19
Harmonic generation in the limit of ultra-steep density gradients is studied experimentally. Observations demonstrate that while the efficient generation of high order harmonics fr…
