Biography

Dr Ludovic Rapp is a Senior Research Fellow at Laser Physics Centre (LPC) at the Australian National University (ANU) and the group leader of the High-Power Laser group. Ludovic has a strong background in ultra-fast laser interaction with matter, ultra-fast laser micromachining and expertise in beam shaping. His research work at ANU on high-pressure material phases formation using ultra-intense laser pulses led to the discovery of two new high-density phases of Silicon, published in Nature Communications. His research interest also includes laser cleaning, laser dentistry, complex beam formation, and advanced laser processing. Dr Rapp participated in two European 7th Framework Programme: “Ultrafast High-Average Power Thin-Disk Oscillators and Amplifiers” and “Laser printing of organic/inorganic material for the fabrication of electronic devices”, two ARC Discovery Projects: “Ultra-fast alchemy: A new strategy to synthesise super-dense nanomaterials” and “Non-equilibrium material phases”, and one ARC Linkage Project: “Laser cleaning processes for Roads and Maritime Services”.

Physics 2 builds on Physics 1, PHYS1101, with a greater emphasis on mathematical techniques. It is an essential course for any student intending to study physics in later years as it introduces foundational knowledge in the areas of waves and optics, mathematical physics, stationary action principles, and special relativity. The course develops experimental and mathematical methods as parts of an integrated approach to physics.

This course together with Physics 1 provide the basis for further study of physics. They underpin the study at second year level of the core physics areas of: quantum mechanics, statistical and thermal physics, electromagnetism, and classical physics.

Learning Outcomes:
Understand the concepts of special relativity, including: the postulates, time dilation, length contraction and the relativity of simultaneity.
Be able use the Lorentz transformations for event coordinates.
Understand the stationary action principle and its origin in quantum mechanics.
Be able to derive the Euler-Lagrange equations for simple mechanical systems.
Be able to take a wide range of physical situations, model them using differential equations, and effectively use the solutions.
Be able to set up and compute 3D integrals of both scalar and vector quantities and use them to compute physical quantities such as electric fields and moments of inertia.
Be able to model physical systems as damped, driven and coupled harmonic oscillators.
Be able to apply physics principles to the solution of problems, including complex problems, and to the conduct of experiments.
Have developed laboratory skills including equipment skills, data gathering and analysis, estimation and interpretation of uncertainties and, experiment design, and presentation.

Publication highlights

Experimental evidence of new tetragonal polymorphs of silicon formed through ultrafast laser induced confined micro explosion 
L. Rapp, B. Haberl, C.J. Pickard, J.E. Bradby, E.G. Gamaly, J.S.Williams, S. Juodkazis, A.V. Rode 
Nature Communication 6:7555 (2015)

A study demonstrating the formation of two novel metastable Si phases by the ultrafast laser induced confined microexplosion method, predicted theoretically but never observed in nature or in laboratory experiments. Theoretical prediction of four more new Si-allotropes with 32 atoms in a primitive cell, two tetragonal and two monoclinical.

“The real breakthrough has happened in 2015 when Rapp et al. have found evidence for several metastable silicon phases after ultrashort laser-induced confined microexplosions[..]. They have determined the lattice parameters and possible atomic structures of [...] phases: [...] The exotic silicon phases and those new discovered by Rapp et al. have provided a novel insight into the local structure and properties of the amorphous phase of silicon.” Dmitrienko et al., Phys.

Scientific report 6 34286 (2016)

A study demonstrating the creation of high aspect ratio nanochannels inside sapphire crystal using Bessel beam, opening novel perpectives for laser processing and new materials synthesis by laser-induced compression.

“The technique can be applied to generate through holes in a single shot event with high reliability and efficiency, Rapp et al[...] These beams enable overcoming many of the difficulties usually encountered with standard Gaussian beam[..] can significantly benefit from advanced optical solutions that are able to master not only the efficiency of the process but equally the dimensional and the structural characteristics[..] with increased levels of control.” Stoian et al., Adv.
