Dynamical generation of phase-squeezed states in a two-component Bose-Einstein condensates
G. R. Jin, Y. An, T. Yan +1
As an "input" state of a linear (Mach-Zehnder or Ramsey) interferometer, the phase-squeezed state proposed by Berry and Wiseman exhibits the best sensitivity approaching to the Hei…
Quantum-limited metrology in the presence of collisional dephasing
Y. C. Liu, G. R. Jin, L. You
Including collisional decoherence explicitly, phase sensitivity for estimating effective scattering strength of a two-component Bose-Einstein condensate is derived analytically…
A Pair of Disjoint 3-GDDs of type g^t u^1
Yanxun Chang, Yeow Meng Chee, Junling Zhou
Pairwise disjoint 3-GDDs can be used to construct some optimal constant-weight codes. We study the existence of a pair of disjoint 3-GDDs of type and establish that its n…
Van der Waals epitaxy of Bi2Se3 on Si(111) vicinal surface: An approach to prepare high-quality thin films of topological insulator
H. D. Li, Z. Y. Wang, X. Kan +7
Epitaxial growth of topological insulator Bi2Se3 thin films on nominally flat and vicinal Si(111) substrates is studied. In order to achieve planner growth front and better quality…
Polarization squeezing and multipartite entanglement of triphoton states
G. R. Jin, S. Luo, Y. C. Liu +2
Based upon standard angular momentum theory, we develop a framework to investigate polarization squeezing and multipartite entanglement of a quantum light field. Both mean polariza…
