Russell J. Hemley
University of Illinois Chicago
Extreme conditions, and in particular extreme pressures and temperatures, produce profound effects on condensed matter, leading to the creation of new, potentially useful materials. A growing number of novel materials and phenomena are being documented over a broad range of pressures (e.g., to millions of atmospheres or hundreds of gigapascals) at a new generation of both small- and large-scale experimental facilities. In many cases guided by theory, recent results include unusual transitions between insulating and metallic phases, new topological materials and ferroelectrics, novel superhard materials, transitions in soft matter, and new materials that may comprise planetary interiors. These studies include our discovery of new classes of hydrogen-rich materials that exhibit very high Tc superconductivity in the vicinity of room temperature. The implications of these materials discoveries span science and engineering, including the development of new technologies.

Topological Superconductivity, Majorana Zero Modes and Quantum Algorithms
Dirk K. Morr
University of Illinois Chicago
The discovery of topological superconductivity and the Majorana zero modes they harbor was an important step towards the realization of topological quantum computing. In this talk, I will review some recent progress in the theoretical prediction and experimental realization of novel topological superconducting phases – ranging from strong, weak and higher order topological superconductors to topological nodal-point superconductivity -- in magnet-superconductor hybrid (MSH) systems. I will demonstrate how the real-time manipulation of the magnetic structure in MSH systems provides a new path to braiding MZMs, revealing their non-Abelian statistics, and to the creation of topological quantum gates and quantum algorithms.
