NoSymmetry
[source]¶Bases: kwant.system.Symmetry
A symmetry with a trivial symmetry group.
Methods
act
(element, a, b=None)[source]¶Act with symmetry group element(s) on site(s) or hopping(s).
Group element(s) with which to act on the provided site(s) or hopping(s)
Site
or SiteArray
If Site then element
is a single tuple, if SiteArray then
element
is a single tuple or a sequence of tuples.
If only a
is provided then element
acts on the site(s)
of a
. If b
is also provided then element
acts
on the hopping(s) (a, b)
.
has_subgroup
(other)[source]¶Test whether self has the subgroup other…
or, in other words, whether other is a subgroup of self. The reason why this is the abstract method (and not is_subgroup) is that in general it’s not possible for a subgroup to know its supergroups.
