Explore the design of Ru-based quantum spin liquid candidates and their experimental signatures in this 49-minute conference talk by Roser Valenti from Goethe-Universität Frankfurt. Delve into microscopic modeling techniques and learn about recent progress in quantum magnetism as part of the Dynamical Response and Transport in Quantum Magnets conference at the Kavli Institute for Theoretical Physics. Discover how entangled spin, orbital, and lattice degrees of freedom contribute to the complexity of magnetic materials and the emergence of low-energy quantum gauge theories. Gain insights into the search for novel topologically-ordered states of matter, dynamical and transport properties revealing fractionalization, and the roles of disorder and spin-phonon interaction in quantum magnets.
