It is found that the wet (unbound) and the nonwet (pinned) states coexist and are both thermodynamically stable in a domain of the dynamical parameters that define the model. startxref 0000052494 00000 n By continuing you agree to the use of cookies. 0000015022 00000 n These effects are described theoretically using an action that takes into account the competition between different order parameters.
