Visualizing 3D tight-binding models

This example demonstrates how to visualize a 3D tight-binding model using the TBModel.visualize_3d function.

Note

This feature requires the plotly library to be installed.

You can install it via pip:

pip install plotly

or via conda:

conda install plotly

from pythtb.models import fu_kane_mele

# Reference Model
t = 1  # spin-independent first-neighbor hop
soc = 1  # spin-dependent second-neighbor hop
dt = [2, 0, 0, 0]  # hopping modulation along (111) direction
fkm_model = fu_kane_mele(t, soc, dt=dt)

fig = fkm_model.visualize_3d(draw_hoppings=True)
