Exchange interaction in quantum rings and wires in the Wigner-crystal limit
Michael M. Fogler, Eugene Pivovarov
We present a controlled method for computing the exchange coupling in correlated one-dimensional electron systems based on the relation between the exchange constant and the pair-c…

Spin exchange in quantum rings and wires in the Wigner-crystal limit
Michael M. Fogler, Eugene Pivovarov
We present a controlled method for computing the exchange coupling in strongly correlated one-dimensional electron systems. It is based on the asymptotically exact relation between…
