sys_leads_hopping_pos
(sys, hop_lead_nr)[source]¶Return arrays of coordinates of all hoppings in a system.
~kwant.builder.Builder
or ~kwant.system.System
instanceThe system, coordinates of sites of which should be returned.
(hopping, leadnr, copynr)
tuplesOutput of sys_leads_hoppings
applied to the system.
Array of coordinates of the hoppings. The first half of coordinates in each array entry are those of the first site in the hopping, the last half are those of the second site.
Notes
This function uses site.pos
property to get the position of a builder
site and sys.pos(sitenr)
for finalized systems. This function requires
that all the positions of all the sites have the same dimensionality.
