-
A.
La2CuO4
chosen
La2CuO4 is a copper-oxide compound that serves as the undoped parent material of high-temperature cuprate superconductors, exhibiting strong electron correlations and antiferromagnetic order.
-
B.
Sr2CuO2Cl2
Sr2CuO2Cl2 is a layered copper-oxide compound widely studied as a prototypical parent material of high-temperature superconducting cuprates, notable for its strong electron correlations and antiferromagnetic order.
-
C.
London theory of superconductivity
The London theory of superconductivity is a foundational phenomenological model that explains key electromagnetic properties of superconductors, such as perfect diamagnetism and the Meissner effect, through the London equations.
-
D.
V2O3
V2O3 (vanadium(III) oxide) is a transition metal oxide known for its temperature- and pressure-dependent metal–insulator transition, making it a classic system for studying strong electron correlations and Mott physics.
-
E.
Schrieffer
Schrieffer is the surname of John Robert Schrieffer, the American physicist and Nobel laureate known for co-developing the BCS theory of superconductivity.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
