Tour 2: A tight-binding model on a square lattice
|
|
-------------------------------------------------
|
|
|
|
Let us now consider free fermions on a Bravais lattice.
|
|
We will set up a square lattice with the nearest
|
|
neighbour hopping using the ``BravaisLattice`` class of TRIQS, compute its
|
|
density of states (DOS) and then plot it by using again the ``oplot`` function.
