DNA Molecule as a Spin System and the Symmetric Top Model
نویسنده
چکیده
It is observed that when the conformational properties of DNA molecule are mapped onto an antiferromagnetic spin system we can realize the specific properties of the rod-like-chain (RLC) model where the analytically continued partition function corresponds to the symmetric top Hamiltonian. The relevant path integral represents a charge particle in the field of a non-quantized monopole which suggests that angular momentum is not quantized. However in a spin chain the nonquantized monopole charge appears in the renormalization group flow and corresponds to the Barry phase required by a spin 1⁄2 state in an entangled spin system. Thus avoids the RLC model crisis.
