What happens when two black holes collide? How can we generate electricity by mimicking photosynthesis? Would you like to discovery earth-like exoplanets, build a quantum computer, or image myelin in the human brain? Find out how - pursue a degree in the Department of Physics & Astronomy! This event is for students who are interested in entering a physics and/or astronomy degree program in their second year of study.

Atomic-wide electron beams can be produced routinely in aberration-corrected scanning transmission electron microscopes. Each probe electron carries impulse-like electric fields which can couple to the charge-density fluctuations of the probed system resulting in a large variety of excitations (phonons, plasmons, etc). Measurements of the amounts of energy and momentum transferred during those scattering processes allow the analysis of properties of the many-particle system that are relevant to the scattering of the probe.

The nature of topological phases in solid state systems is a key outstanding research question, as it has been posited to play a critical role in enabling experimental realization of non-abelian statistics and emerging technologies such as topological quantum computation. In this talk, I will discuss how exotic phenomena can arise from the interplay of ferromagnetism and topology in relativistic materials and how these novel phases can be harnessed to build the next generation of quantum devices.

Solid state materials are classified broadly as insulators, semiconductors, metals or superconductors based on their electrical properties. A superconductor possesses an electronic ground state with zero electrical resistance and total expulsion of magnetic fields. The origin of superconductivity has been a focus since its discovery in 1911, especially following the discovery of high temperature superconductivity in cuprates. Indeed, the nature of high-temperature superconductivity in cuprates remains a defining challenge.

The 2004 isolation of graphene did more than introduce massless Dirac fermions to device physics -- it also introduced the Scotch tape exfoliation method. In this method, we create micron-sized and atomically-thin single crystals by repeatedly cleaving bulk layered crystals. This provides a new pathway for thin film synthesis complementary to more established techniques.

Neutrino oscillation measurement has entered a precision era. In summer 2017, T2K disfavoured the CP-conserving phases of δcp=0,π at 2σ level. CP asymmetry in neutrino and anti-neutrino νμ->νe appearances can be as large as 20% depending on the CP phase δcp, which is within the reach of new projects, HyperK and DUNE. HyperK aims at a statistical error of ~3% for the asymmetry. It is essential to control the systematic uncertainties well below the statistical errors for the discovery.

Remarkable emergent states of matter can be found in materials that are dominated by strong quantum effects. These quantum materials have repeatedly shifted the paradigm in condensed matter physics, proving their fundamental importance; however, these materials also hold tremendous promise for real-world applications. One particularly intriguing state is the quantum spin liquid: a strongly entangled magnetic fluid that represents the greatest departure from classical physics.

Dr. Nicolas Gauquelin
In this seminar I will walk you through my career as a scientist and use a few examples of my research to explain you how I have evolved from a chemist doing materials science to a physicist using advanced electron microscopes. One of the major fields of research in solid state physics over the last decade is the research of innovative non-silicon based electronics. The aim is to make smaller and more powerful electronic devices. This, however, requires fundamental research in the field of condensed matter physics, so new phenomena can be observed.
