Berry Curvature and Curvature Tensor
When the curvature tensor (from Einstein's theory) has a non-zero torsion, it is said to be an antisymmetric tensor in the last two indices composed of the connections of the field. Alternatively, the ...

Numerical Calculation of Berry Curvature
I am trying to calculate some berry curvature (BC) in a 2D lattice and I have some things I am getting lost with.
In the 2D lattice, we set up the eigenvalue problem $H|u_1\rangle = \epsilon_i|u_i\...
