F15.00001: Adler Lectureship Award (2022): The Joy of Magnetism Invited Speaker: Axel Hoffmann Magnetic materials have been the object of human curiosity for thousands of years and even at a very young age many of us find magnets fascinating toys to play with. At the same time, magnetic materials are central to our modern information-driven society, since ultimately almost all digital data is currently stored magnetically. Thus, understanding how to manipulate magnetism at the nanoscale satisfies both our drive to obtain a better fundamental understanding of the world, as well as providing a sustainable future. Towards this end, magnetic multilayers have harbored a font of surprising complexity that give rise to many new applied opportunities. Here interfacial symmetry breaking, the coupling of spins to their orbital motion, and the strong non-linearities of magnetization dynamics generate an abundance of unexpected phenomena. These range from novel approaches of generating spin currents over different ways how topology influences magnetic systems to complex magnetization dynamics that may emulate the function of the natural brain. In this talk, I will highlight some of the magnetic effects that brought joy to my own scientific work. These include, spintransport in antiferromagnets, blowing of magnetic bubbles, and curveballs with magnons. |

F15.00003: IUPAP C10 Young ScientistPrize Winner: Unveiling the realm of quantum materials with nano-optics Invited Speaker: Alexander S McLeod Toolsets wielded by condensed matter researchers over the past century have expanded meteorically into frontiers of the ultra-small and ultra-fast, today leveraging advancements like atomically precise crystal growth, nano-scale device assembly, and femtosecond spectroscopy with ultrafast photon pulses. On the other hand, despite breathtaking 20th century advancements in photon sources and detection technologies, our capacity to resolve condensed matter through optical spectroscopies has remained largely arrested by the diffraction limit since its 19th century observation by Ernst Abbe. However, recent decades have seen the marriage of "conventional" optics with scanning probes to circumvent the diffraction limit, realizing a nanometer-resolved optical spectroscopy mediated fundamentally by electromagnetic near-fields. In this talk, I review and celebrate the breakthrough of this technique into regimes of low temperature and nanometer spatial scales necessary for fundamental studies of quantum materials. I showcase seminal investigations of collective excitations in 2-dimensional media like graphene, electronic phase competition in correlated electron solids, and on-demand control of optical properties in strongly interacting materials. I will share my ambitious perspectives for the future of nano-optical probes for quantum materials, a future that is simultaneously ultra-bright and ultra-small, and fundamentally transformative for optical spectroscopies of complex matter. |

F15.00004: Greene Dissertation Award (2022): Tunable strongly coupled superconductivity in magic-angle twisted trilayer graphene Invited Speaker: Yuan Cao Magic-angle twisted trilayer graphene (MATTG) was recently discovered as a novel system for exploring moire superconductivity and more generally, correlated electrons in 2D graphene superlattices. The observed behavior in in-plane magnetic fields pointed towards a non-spin-singlet pairing in its superconducting state, which could possibly be non-s-wave as well. In this talk, I will present some recent experimental progress in the understanding of the puzzling phenomenology in this system. |
