Quantum Phase Transition in Antiferromagnetic Heisenberg Chains Coupled to Phonons
Satoru Akiyama, Chitoshi Yasuda
We develop an analytical approach based on a unitary transformation to investigate S=1/2 antiferromagnetic Heisenberg chains coupled to phonons, and find a new quantum phase transi…
Stability of the rotating SU(3) Skyrmion
Satoru Akiyama, Masahiro Kawabata
The profile functions of the SU(3) Skyrme soliton are investigated for the octet, decuplet, and antidecuplet baryons by the mean field approach. In this approach, the profile funct…
Quantum corrections to the masses of the octet and decuplet baryons in the SU(3) chiral quark soliton model
Satoru Akiyama, Yasuhiko Futami
Mesonic fluctuations around the chiral solitons are investigated in the SU(3) chiral quark soliton model. Since the soliton takes the non-hedgehog shape for the hyperons and the he…
Nonrigid chiral soliton for the octet and decuplet baryons
Satoru Akiyama, Yasuhiko Futami
Systematic treatment of the collective rotation of the nonrigid chiral soliton is developed in the SU(3) chiral quark soliton model and applied to the octet and decuplet baryons. T…
Instability of the hedgehog shape for the octet baryon in the chiral quark soliton model
Satoru Akiyama, Yasuhiko Futami
In this paper the stability of the hedgehog shape of the chiral soliton is studied for the octet baryon with the SU(3) chiral quark soliton model. The strangeness degrees of freedo…
