Physics@Veldhoven Master classes

Master classes 2018

Julia Yeomans, Hari Manoharan, Johanna Stachel and Chris Murray will give the Physics@Veldhoven 2018 master classes.

Please note the master classes take place on Monday evening 22 January 2018, 19.30-22.00 hours.

On Monday evening, prior to Physics@Veldhoven 2018, the programme committee is organising four master classes. These master classes offer PhDs and young postdocs a unique opportunity to receive an introduction to several hot topics from top researchers. Just 25 places are available for each master class.

You can register for the master classes on the meeting registration form. Please make sure that the topic of your thesis and your seniority in the PhD programme are filled out. If more PhD students apply than can be accommodated by the master class, preference will be given first by topic, then by seniority, then by random selection.

All abstracts of the master classes of Physics@Veldhoven 2018 are not available yet.

Abstract Johanna Stachel
The phenomenology of relativistic nuclear collisions und the quest for understanding matter in the early universe
Here I intend to focus on various way to measure temperature, time scales and expansion dynamics in relativistic nuclear collisions and linking them to epocs in the (early) universe and similar observables, where appropriate.

Abstract Julia M. Yeomans
Hot topics in active matter
The masterclass will focus on a selection of the following areas in active matter, also depending on the student audience:
1. swimming in viscous and viscoelastic fluids
2. confined active matter
3. collective cell behaviour as an active system
4. active turbulence in 3D
Yeomans will summarise the work of her group, and related research, followed by discussion and short presentations from members of the audience whose work is related. Students are invited to give a short presentation on one of the topics above.

Abstract Hari Manoharan
Hacking electrons: new particles and emergent phases in quantum materials assembled atom-by-atom
The observation of massless Dirac fermions in monolayer graphene and topological insulators has propelled a new area of science and technology seeking to harness relativistic charge carriers within solid-state materials. Using low-temperature scanning tunneling microscopy and spectroscopy, we show the emergence of Dirac fermions in fully tunable condensed-matter systems—molecular graphene and related structures—assembled via atomic manipulation of a two-dimensional electron gas. We embed, image, and tune the symmetries underlying the two-dimensional Dirac equation into these electrons by sculpting the surface potential with manipulated molecules. By distorting the electron hopping parameters into a dimerized Kekulé pattern, we find that these natively massless Dirac particles can be endowed with a tunable mass engendered by the associated scalar gauge field, in analogy to the Higgs field. With altered symmetry and texturing, the Dirac fermions can be dressed with gauge electric or magnetic fields such that the carriers believe they are in real fields and condense into the corresponding ground state, as confirmed by tunneling spectroscopy. Using these techniques we have realized a quantum Hall state that preserves time-reversal symmetry, in which electrons quantize into Landau levels in a gauge magnetic field ramped up to 300 Tesla with zero applied laboratory field. These and other chiral phases can be used to guide or confine charge in nontrivial ways and to synthesize new particles.

Abstract Christopher B. Murray
Tutorial on Building with artificial atoms:  The design of multifunctional nanomaterials and devices through nanocrystal self-assembly
The synthesis of monodisperse colloidal nanocrystals (NCs) with controlled composition, size, and shape provides ideal building blocks for the assembly of new thin films and devices. These monodisperse colloidal NCs can be considered "artificial atoms" with tunable electronic, optical, magnetic properties that are allowing the development of a new periodic table for design at the Mesoscale.  I will discuss “best practices” in synthesis, purification, and integration of single phase NCs and core-shell (heterostructures) NCs emphasizing the design of semiconductor building blocks with tunable shapes (spheres, rods, cubes, discs, octahedra, etc... that constitute a new NC “Periodic Table.” I will then present general procedures being employed to assemble these tailored NCs into single-component, binary, ternary NC superlattices providing a scalable route to the production of multi-functional thin films. The modular assembly of these NCs allows the desirable features of the underlying quantum phenomena to be retained and enhanced even as the interactions between the NCs allow new delocalized properties to emerge.   Potential impacts in 3 areas will be discussed in optics and optoelectronics, magnetics and finally in nanostructured catalysts design. Synergies in optical, magnetic and electronic, the coupling between NCs will be emphasized as we are pushing toward the realization of artificial solids and superstructures with a new 3D and structure and high degrees of electronic delocalization.  I will share specific case studies solution-processable NC films can be deposited and patterned on wafer scale and discusses challenges and opportunities in large area deposition applications.

After the conference, video recordings of the master classes will be available to watch via Archives.
