Dipolar coupling hamiltonian
WebOur proposal treats the full Hamiltonian of the 1Σ+ molecule NaCs, utilizing a pair of nuclear spin states as storage qubits. A third rotationally excited state with rotation-hyperfine coupling enables switchable electric dipolar exchange interactions between two molecules to generate an iSWAP gate. All three states are insensitive to external ...

Webin its PAS. The purely dipolar part is expressed by the second, traceless matrix. In Fig. 4 the effect of the hyperfine coupling on the energy level diagram and the EPR spectrum is illustrated for the simple case of isotropic EZI and HFI for a spin I = 3/2 (e.g. Cu 2+) 2.The coupling between the electron and nuclear spin results in a splitting of each electron …
WebSep 12, 2003 · De novo structure determination on the basis of dipolar couplings has also been demonstrated, but remains challenging if only one-bond heteronuclear dipolar couplings are available (50–52). In this case, the lack of distance restraints makes it difficult to correctly translate elements of well-defined local structure relative to one another. lindy hop bostonWebDipolar Coupling 8.1 Hamiltonian As discussed in the first lecture, a nucleus with spin I ≥ 1/2 has a magnetic moment, µ, associated with it given by µ~ = γL~.
