Energy Optimal Interpolation in Quantum Evolution
Xiao Ge, Zhan Xu
We introduce the concept of interpolation in quantum evolution and present a general framework to find the energy optimal Hamiltonian for a quantum system evolving among a given se…
Degree of entanglement for bipartite pure states

Skyrmion Excitation in Two-Dimensional Spinor Bose-Einstein Condensate
Hui Zhai, WeiQiang Chen, Zhan Xu +1
We study the properties of coreless vortices(skyrmion) in spinor Bose-Einstein condensate. We find that this excitation is always energetically unstable, it always decays to an uni…
Entanglement Properties of Some Fractional Quantum Hall Liquids
Bei Zeng, Hui Zhai, Zhan Xu
We study the entanglement properties of some fractional quantum Hall liquids. We calculate the entanglement of the Laughlin wave function and the wave functions that are generated…
Differential Geometrical Formulation of Gauge Theory of Gravity
Ning Wu, Zhan Xu, Da-Hua Zhang
Differential geometric formulation of quantum gauge theory of gravity is studied in this paper. The quantum gauge theory of gravity which is proposed in the references hep-th/01091…
Determination of Cosmological Constant from Gauge Theory of Gravity
Ning Wu, Germano Resconi, Zhan Xu +3
Combining general relativity and gravitational gauge theory, the cosmological constant is determined theoretically. The cosmological constant is related to the average vacuum energ…
