WebbAs a consequence, one can simply implement the rotation by performing the Peierls substitution, i.e., replacing the hopping term in Hamiltonian ( 2) with (4) where the Peierls phase is proportional to the Coriolis force. Notice that the interaction term , as well as the single-particle-potential term are left unchanged by the Peierls substitution. WebbTwo new one-dimensional (1-D) molecular solids, [CH 2 = CH-BzPy][Pt(mnt) 2] (1) and [CH 2 = CH-BzPy-d 5][Pt(mnt) 2] (2) where CH 2 = CH-BzPy-d 5 + = 1-N-(4-vinylbenzyl) pyridinium-d 5 and mnt 2− = maleonitriledithiolate, were synthesized and characterized.
