Question: physicist of which of the following university has recently discovered the strange metal?
a) Brown University
b) Yale University
c) Cornell University
d) None of these
Answer: (a)
Related Facts:-
- A research team co-led by a Brown University physicist has discovered the strange metal.
- The research regarding the metal was published in the journal Nature.
- The team found strange metal behavior in a material in which electrical charge is carried not by electrons, but by more wave-like entities called Cooper pairs.
- It should be known that conventional charge carriers as electrons belong to a class of particles called fermions, but Cooper pairs act as bosons, which follow very different rules from fermions.
- This is the first time strange metal behavior has been seen in a bosonic system.
- Researchers are hopeful that the discovery might be helpful in finding an explanation for how strange metals work
- The team used a cuprate material called yttrium barium copper oxide patterned with tiny holes that induce the Cooper-pair metallic state.
- The team cooled the material down to just above its superconducting temperature to observe changes in its conductance.
- They found, like fermionic strange metals, a Cooper-pair metal conductance that is linear with temperature.
