SUMMARY
The discussion focuses on calculating and comparing the Fermi velocity of two metals with energy bands described by E=Ak² and E=Bk², where A>B and both have equal Fermi energy. The relationship between Fermi energy and velocity is crucial for this calculation. The Fermi velocity can be derived from the equation v_F = √(2E_F/m), where E_F is the Fermi energy and m is the effective mass of the electrons. Understanding these relationships allows for a clear comparison of the Fermi velocities of the two metals.
