comment Symmetries of a Uniform Magnetic Field
Thanks for the detailed reply. Is there any physical significance to the constants $\mathbf{b}$ and $\phi$?

comment Helicity and Pseudospin in Graphene
Thanks for the reply! If we can tweak the basis to make both $K$ and $K'$ fit the definition of the helicity operator, does that mean the concept of helicity/chirality is not so useful when discussing scattering between the two valleys?

comment Can the Berry Connection be derived from a metric?
Ok cool thanks. So if that's not true, my question still holds: Does a metric exist such that the Berry Connection is a Levi-Civita connection?

comment Does electron-electron scattering contribute to resistivity?
So... Have we reached consensus in this debate? Or still in disagreement?
