BondHoppings

class hubbard.plot.BondHoppings(H, annotate=False, off_diagonal_only=True, **kwargs)[source]

Bases: Plot

Plot matrix element of a tight-binding Hamiltonian in real space

Parameters:

  • H (sisl.Hamiltonian or hubbard.HubbardHamiltonian object) – tight-binding Hamitlonian

  • annotate (bool, optional) – if True it annotates the numerical value of the matrix element

  • off_diagonal_only (bool, optional) – if True it also plots the onsite energies

Methods

__init__(H[, annotate, off_diagonal_only])

add_colorbar(layer[, pos, size])

Add figure colorbar

close()

Close figure

legend(**kwargs)

Add legend to figure.

savefig(fn)

Set maximum and minimum y-axis values
add_colorbar(layer, pos='right', size='5%')

Add figure colorbar

Parameters:

  • layer (matplotlib.cm.ScalarMappable) – i.e., AxesImage, ContourSet, etc. described by this colorbar
