Solutions of a noncommutative nonisospectral Kadomtsev-Petviashvili equation are given in terms of quasiwronskian and quasigrammian respectively. These solutions are verified by direct substitutions. Dynamics of some ...

We present that the local unitary equivalence of n-party pure states is consistent with that of their(n-l)-party reduced density matrices.As an application,we obtain the local invariants for a class of tripartite pure...

We theoretically investigate the spin-dependent electron transport properties in a magnetic superlattice (MSL) with broken two-fold symmetry. An abnormal barrier in the MSL can break the two-fold symmetry of the sys...

Field emissions (FE) from La-doped zinc oxide (ZnO) films are both experimentally and theoretically investigated. Owing to the La-doped effect, the FE characteristic of ZnO films is remarkably enhanced compared wi...
