    A Bloch theory on hexagonal lattice

    Thanks for your help. My first goal was write down the components of equation. For this i define ##\mathbf G=l\mathbf g_1 + p\mathbf g_2 ## in a loop for ##l## and ##p## from 1 to 10 and created a 2x100 matrices. As i understand ##\mathbf G## is like translation vector ##\mathbf T## in...

    A Bloch theory on hexagonal lattice

    Thank you for your answer. I'am trying to reproduce Figure 1 in the paper in a manner of better understanding. I have read related topics from Ashcroft & Mermin and Michael P. Marder's books but still i am not able to do numerical calculations. After i created 2x100 matrices for ##\mathbf G## i...

    A Bloch theory on hexagonal lattice

    Hello, i am new in condensed matter physics and studying the article 'Engineering artificial graphene in a two-dimensional electron gas' (Gibertini et al., 2009). I read a lot about bloch theorem lately and i got the main idea but still i don't understand the component of the equation. In the...
