Frustrated Spin Model as a Hard-Sphere Liquid
D topology antiferromagnetic ising model triangle lattice hard sphere fluid to the quantum spin dynamics
2014/12/20
We show that one-dimensional topological objects (kinks) are natural degrees of freedom for an antiferromagnetic Ising model on a triangular lattice. Its ground states and the coexistence of spin orde...
Time reparametrization symmetry in a short-range p-spin model
Time reparametrization symmetry short-range p-spin model
2010/11/19
We explore the existence of time reparametrization symmetry in the p-spin model. Using the Martin-Siggia-Rose generating functional, we analytically probe the long-time dynamics. We perform a Renormal...
Effective spin model for interband transport in a Wannier-Stark lattice system
Effective spin model interband transport Wannier-Stark lattice system
2010/10/29
We show that the interband dynamics in a tilted two-band Bose-Hubbard model can be reduced to an analytically accessible spin model in the case of resonant interband oscillations. This allows us to pr...
Spin-spin correlation functions of the q-VBS state of an integer spin model
Spin-spin correlation functions q-VBS state integer spin model

We consider the valence-bond-solid ground state of the q-deformed higher-spin AKLT model (q-VBS state). We investigate the eigenvalues and eigenvectors of a matrix (G matrix), which is constructed fro...
The qubit states decoherence in antiferromagnet-based nuclear spin model of quantum register

This study deals with the further development of nuclear spin model of scalable quantum register, which presents the one-dimensional chain of the magnetic atoms with nuclear spins 1/2, substituting th...

Spin quantum constant neutron model Intrinsic Velocity
2007/6/7
Based on the concept that the electron and proton are manacled by own magnetic field，a Resonance Ring Model for spin of electron and proton and new calculation method of quantum constants are describe...
