CM Seminar: Muons for the Quantum Matter
2355 East Mall
Research Scientist, TRIUMF and
Affiliated Associate Professor, SBQMI
A S=1/2 polarized particle, which may couple to the near-by electron is the simplest quantum mechanical object, as you may find in the standard text books. In reality, a particle called positive muon (µ+), provides such experimental observations. TRIUMF in the UBC south campus, which is also my home institute since this August, provides muon beams for material science research.
In the seminar this time, I would like to introduce some of my research work in which muons played important roles.
The subject involves phase diagram of iron pnictide superconductors , electrides [2,3] and wide gap semiconductors.
The muon characterization has the feature of a sensitive magnetic probe as well as a Hydrogen isotope which extracts its electronic state in the dilute limit.
