SUMMARY:Origins of nematicity and field-induced superconductivity in i
 ron-based materials\, Physics Department Colloquium\, Shua Sanchez\, P
 ostdoctoral Fellow\, MIT
DESCRIPTION:Materials with strongly correlated electrons can give rise
  to interesting and useful phenomena\, such as nematicity\, magnetism\
 , and unconventional superconductivity. In these systems\, the charge\
 , spin\, and lattice degrees of freedom become intertwined\, such that
  the origin of these phenomena becomes obscured. In this talk\, I will
  discuss a new experimental platform which combines tunable applied st
 rain\, transport measurements\, and several x-ray techniques to probe 
 the origin and mechanisms of strongly correlated phases. I will review
  three recent studies in iron-based superconductors\, which examine (1
 ) the transport-structural correspondence in the nematic phase of dope
 d BaFe2As2\, (2) the orbital driver of nematicity in FeSe\, and (3) th
 e mechanism of field-induced superconductivity in ferromagnetic doped 
 EuFe2As2. These diverse investigations demonstrate the power and promi
 se of multimodal characterization for solving other puzzles in strongl
 y correlated materials.<br>
