Abstract
This paper presents the parastatistics of braided Majorana fermions obtained in the framework of a graded Hopf algebra endowed with a braided tensor product. The braiding property is encoded in a t-dependent 4×4 braiding matrix Bt related to the Alexander-Conway polynomial. The nonvanishing complex parameter t defines the braided parastatistics. At t=1 ordinary fermions are recovered. The values of t at roots of unity are organized into levels which specify the maximal number of braided Majorana fermions in a multiparticle sector. Generic values of t and the t=−1 root of unity mimick the behaviour of ordinary bosons.
Author comments upon resubmission
following your request of a minor revision I have inserted a paragraph
explaining why the Z_2-graded qubits describe Majorana fermions.
Two extra references ([10] and [11]) have been added with respect
to the previous version.
Sincerely Yours,
Francesco Toppan
List of changes
A paragraph (4 lines) has been added after formula (3) at page 2:
from “The excited state is a Majorana …”
till “ … (implying that the charge conjugation operator is the identity).”
Two extra references ([10] and [11]) have been added.
