Abstract
A new extensive variable and its conjugate field II are introduced for the Kasteleyn dimer model on the honeycomb lattice via an isomorphic membrane-polymer chain model. The resultant phase diagram has a first-order phase line, thereby revealing a non-local order parameter in this model for the first time. The first-order line terminates in a critical point with critical exponents , , and . The -order exponents appear on the line .
