### Abstract

In this paper, it is shown that Dirac’s Hamiltonian and Bogoliubov’s Hamiltonian both can be braid group matrix representations which are new type of four-dimensional matrix representation of the braid group in comparison with the well-known type (Ge et al. in Int J Mod Phys A 6:3735, 1991; Ge et al. in J Phys A 24:2679, 1991; Ge and Xue in Phys Lett A 152:266, 1991; Ge et al. J Phys A 25:L807 1992) related to the usual spin models. The Dirac’s Hamiltonian is for a free electron with mass m while the Bogoliubov’s Hamiltonian is for quasiparticles in $$^{3}He$$ 3 H e -B with the same free energy and mass being $$\frac{m}{2}$$ m 2 which depends on the momentum p. And this type is known that the braid matrices are related to the anyon description for FQHE with $$\nu =\frac{1}{2}$$ ν = 1 2 (Nayak et al. in Rev Mod Phys 80, 2008; Slingerland and Bais in Nucl Phys B 612:229, 2001), this may mean that Dirac particle could be decomposed into anyons based on the braid group relation. We also get the Temperley-Lieb matrix representations corresponding to the braid group matrix representations and investigate the entanglement and Berry phase of the corresponding Dirac system.
