Goldman selected to receive $7.5M MURI Award

Professor Rachel S. Goldman

MSE is excited to announce that a team led by Professor Rachel S. Goldman recently received a major DoD Multidisciplinary University Research Initiative (MURI) Award for the project "Hosting Exotic One-Dimensional Topological States with Dislocations."

For decades, line defects (dislocations) have been considered detrimental for electronic and optoelectronic devices. With the latest advances in theories for topological states of matter, and the development of precise methods to control the densities and configurations of dislocations, the possibility for a new frontier has emerged, in which dislocations are predicted to host 1D quantum conducting states with full spin-momentum locking.  In this synergistic computational-experimental approach, we aim to understand and control 1D topological states associated with dislocations, thereby opening a new frontier in condensed matter research and education. Dislocation modes with lossless ballistic transport offer a new opportunity to mediate electrical signals in 3D space. The locking of spin with momentum allows dramatically enhanced spin pumping efficiency for spintronic applications. Furthermore, the edges of these 1D quantum conductors can host Majorana modes, a key ingredient needed to build topological quantum computers.

Co-principal investigators include: 

Cagliyan Kurdak, Physics, U-M

Kai Sun, Physics, U-M

Ctirad Uher, Physics, U-M

Harley T. Johnson, Mechanical Science and Engineering, UIUC

Minjoo Larry Lee, Electrical and Computer Engineering, UIUC

The project is supported by the Air Force Office of Scientific Research and is one of 31 projects involving 61 academic institutions selected to receive a total of $220 million. 

Since its inception in 1985, the Department’s MURI program has funded teams of investigators with the hope that collective insights from multiple disciplines could facilitate the growth of cutting-edge technologies to address the Department’s unique problem sets. The highly competitive MURI program, which complements the Department’s single-investigator basic research grants, has made immense contributions to current and future military capabilities and resulted in multiple commercial sector applications. Notable MURI achievements include breakthroughs in cold atom quantum methods with potential applications in quantum sensing and communication as well as advances in pulsed magnetic field propagation and Doppler radar detection leading to new detection physics for landmines.
