The entropy of co-compact open covers
Zheng Wei, Yangeng Wang, Guo Wei
Co-compact entropy is introduced as an invariant of topological conjugation for perfect mappings defined on any Hausdorff space(compactness and metrizability not necessarily requir…
Spin transfer in ultrathin BiFeO3 film under external electric field
Hong-Jian Feng
First-principals calculations show that up-spin and down-spin carriers are accumulating adjacent to opposite surfaces of BiFeO3(BFO) film with applying external bias. The spin carr…
Probing Planckian physics in de Sitter space with quantum correlations
Jun Feng, Yao-Zhong Zhang, Mark D. Gould +3
We study the quantum correlation and quantum communication channel of both free scalar and fermionic fields in de Sitter space, while the Planckian modification presented by the ch…
Notes on teleportation in an expanding space
Jun Feng, Wen-Li Yang, Yao-Zhong Zhang +1
We investigate the quantum teleportation between a conformal detector Alice and an inertial detector Bob in de Sitter space in two schemes, (i) one uses free scalar modes and (ii)…
Asymptotic normality of maximum likelihood and its variational approximation for stochastic blockmodels
Peter Bickel, David Choi, Xiangyu Chang +1
Variational methods for parameter estimation are an active research area, potentially offering computationally tractable heuristics with theoretical performance bounds. We build on…
Determinant representations for scalar products of the XXZ Gaudin model with general boundary terms
Kun Hao, Wen-Li Yang, Heng Fan +4
We obtain the determinant representations of the scalar products for the XXZ Gaudin model with generic non-diagonal boundary terms.
