The discovery of topological Weyl semimetals in 2017 has revealed opportunities to realize several extraordinary physical phenomena in condensed matter physics. Now, researchers at Chalmers University of Technology have demonstrated the direct electrical detection of a large spin Hall effect in this topological quantum material. Weyl semimetal takes advantage of its strong spin-orbit coupling and novel topological spin-polarized electronic states in its band structure. These experimental findings can pave the way for the utilization of spin-orbit induced phenomena in developing next-generation of faster and energy-efficient information technology and have been published in the scientific journal Physical Review Research.


As our society is becoming more integrated with artificial intelligence (AI) and Internet-of-Things

Hall of Femme 2020: Alyson Connor, MicroMass Communications – Hall of Femme – MM&M

What would you do if you didn’t work in healthcare?  

I’ve spent my entire career in healthcare. It’s my passion and where I feel I can use my strengths to make an impact. I guess if I could do anything else I would be a professional global food critic specializing in desserts. If I could get paid to travel the world, sample the local confections, all while satisfying my sweet tooth, that would be a very satisfying career. I also think I could fall back on being a professional comedian. With three boys and three dogs, the chaos in my house creates comedic material I just can’t make up.   

Can you give a shout-out to someone who helped you at a pivotal time in your career?

Phil Stein has been my partner at MicroMass for 15 years. We always have very spirited conversations that result in thoughtfully considered decisions. Phil
