We further draw an analogy with the appearance of imaginary terms in simple models of barrier scattering, which may help understanding the unusually effective long-range electron transfer in biological systems. Our symmetry analysis helps to identify essential constraints in the theoretical description of the CISS effect. Hence, they are not related to the breaking of time-reversal symmetry resulting from the fact that molecules are open systems in a junction.
These imaginary terms originate from the spin–orbit coupling, and they preserve the Hermitian nature of the Hamiltonian. On the basis of first-principles calculations and analytical considerations, we perform a symmetry analysis of the key quantities determining transport probabilities of electrons of different spin orientations. We are taking an essential step into this direction by analyzing the importance of imaginary terms in the Hamiltonian as a necessary condition for nonvanishing spin polarization in helical structures. The CISS effect is attributed to spin–orbit coupling, but a sound theoretical understanding of the surprising magnitude of this effect in molecules without heavy atoms is currently lacking. Also, CISS-induced spin polarization has a considerable promise for new spintronic devices and the design of quantum materials.
Therefore, the expression is not the same and the function has no symmetry with respect to the origin.The chiral-induced spin selectivity (CISS) effect, which describes the spin-filtering ability of diamagnetic structures like DNA or peptides having chiral symmetry, has emerged in the past years as the central mechanism behind a number of important phenomena, like long-range biological electron transfer, enantiospecific electrocatalysis, and molecular recognition. We see that in this case, the right side of the expression is identical to the original equation, but the left side is different. We remember that a negative number raised to an even power is equal to a positive number. Solution: Again, we have to replace x with -x and y with -y. Determine whether the function $latex y=2+2$ symmetric about the origin?.
