Abstract
A theoretical study is given of the resistance of two ballistic point contacts in series. Nonadditivity of resistances is demonstrated as a result of classical ballistic transport. A rich magnetoresistance behavior is predicted to follow from the interplay of the cyclotron radius, the pointcontact width, and the point-contact separation.Keywords
