Impurity locating
Witryna15 sty 2011 · When the impurity spin locating at the edge site of the three-spin XX chain, after a similar analysis as performed in the above section, one can also show that perfect transfer of an arbitrary one-qubit pure state is also possible by modulating the intensity of the external magnetic field or performing relevant local unitary operations … Witryna23 lut 2007 · In this paper, we present a microscopic study of impurity resonance and tunneling magnetoresistance (TMR) for nanojunctions. We employ the Green’s-function method to derive the tunneling wave functions and TMR from the spintronic model with nonmagnetic impurities and at a finite bias voltage.

WitrynaAn interstitial impurityA point defect that results when an impurity atom occupies an octahedral hole or a tetrahedral hole in the lattice between atoms. is usually a smaller atom (typically about 45% smaller than the host) that can fit into the octahedral or tetrahedral holes in the metal lattice ( Figure 8.4.1 ). Witryna1 cze 2004 · We arrive at a situation that the energy of 4f n levels is determined by the internal properties of the lanthanide ion not effected much by the host. The energy of …
We consider impurities in the simplest 1D Hatano–Nelson chain43, which already exhibits nearly the full scope of impurity-induced phenomena in more generic lattices. An impurity is represented as a modified coupling between the first and last sites: with μ± = μe±α, μ controlling the local impurity, α > 0 and x = 0, … Zobacz więcej To understand why SFA occurs, we analytically solve for the eigenstates \({{{\Psi }}}_{n}=\mathop{\sum }\nolimits_{x}^{L}{\psi }_{x,n}{\hat{c}}_{x}^{\dagger … Zobacz więcej The discussions above imply a duality between PBCs at μ = 1 and quasi-PBCs at μ = e2α. This motivates us to seek duality relations for the whole range of μ. For e−2α ≪ μ ≪1, another set of exponentially decaying … Zobacz więcej As steady-state phenomena, the SFA can be most easily demonstrated in an electrical circuit setting. In place of the Hamiltonian, we consider the circuit Laplacian J which governs its steady-state response via I = … Zobacz więcej The decay exponents κL(μ) of SFA states, as induced by the impurity, are insensitive to the exact configuration of non-reciprocal hoppings in the … Zobacz więcej
