Multi-level run-length-limited read-only optical storage is a kind of high density storage method. The width and height of recording marks are varied with diffe
We propose a robust scheme to generate four-mode entangled states by using the method of adiabatic passage.Our scheme is more insensitive to certain practical s
Metals are typically good conductors in which the abilities to transport charge and to transport heat can be related through the Wiedemann-Franz law. Here we re
Using the Keldysh nonequilibrium Green function and equation-of-motion technique, we have qualitatively studied the spin-dependent transport of a triple-QD syst
