In 1937 Ettore Majorana introduced the concept of what are now fittingly called Majorana fermions -- fermionic particles that are their own antiparticles. Nowadays an active search for condensed-matter analogues of these elusive objects is well underway, motivated by both the prospect of revealing new facets of quantum mechanics and longer-term quantum computing applications. This talk will survey recent advances in this pursuit.
Most populations are spread over spatial ranges much bigger than any one individual will explore in its lifetime. How does the simple fact of this spatial structure affect adaptive evolution and genetic diversity?
I will discuss when space can slow down or speed up adaptation, how adaptation in spatially structured populations restructures even the neutral genetic variation, and how we might be able to use sequencing data as a lens to watch organisms move.
An international team led by researchers from the College of Sciences has made a surprising discovery in the field of 2D materials. Their finding could open a range of novel device applications, but it also raises many questions about the mechanisms involved.
