Under dielectric continuum approximation,interface optical (IO) phonon modes and the Froehlich electron IO phonon interaction Hamiltonian in a multi-shell spher
By using the Holevo-Schumacher-Westmoreland theorem and through solving eigenvalues of states out from the quantum noisy channels directly, or with the help of
We discussed the directed motion and the energy conversion efficiency of a particle in two-state ratchet potentials with white noise. We studied the effective p
