The proposal aims to measure the powder averaged magnetic excitations in KFe2Se3. The compound is related to the recently discovered Fe-Se,As superconductors and is based upon...
Materials with nontrivial topological properties (analogous in a general way to the familiar Moebius strip) are a hot topic in current solid state physics. In particular new materials showing differen
Topological phases have been a central focus of condensed-matter physics for over 50 years. Along with many experimental applications, they have provided much intellectual interest due to their
