Near-Zero Moment Ferromagnetism in the Semiconductor SmN
C. Meyer, B. J. Ruck, J. Zhong +4
The magnetic behaviour of SmN has been investigated in stoichiometric polycrystalline films. All samples show ferromagnetic order with Curie temperature (T_c) of 27 +/- 3 K, eviden…
Ferromagnetic redshift of the optical gap in GdN
H. J. Trodahl, A. R. H. Preston, J. Zhong +4
We report measurements of the optical gap in a GdN film at temperatures from 300 to 6K, covering both the paramagnetic and ferromagnetic phases. The gap is 1.31eV in the paramagnet…
Comprehensive proof of the Greenberger-Horne-Zeilinger Theorem for the four-qubit system
Li Tang, Jie Zhong, Yaofeng Ren +2
Greenberger-Horne-Zeilinger (GHZ) theorem asserts that there is a set of mutually commuting nonlocal observables with a common eigenstate on which those observables assume values t…
Quasi-particle dynamics of a strongly correlated polaron metal
J. Zhong, H. -B. Schuttler
We develop a simple diagrammatic low-energy boson exchange strong-coupling model for an antiferromagnetically correlated polaronic metal. Important low-temperature features of such…
