While avoiding technical derivations of response functions, the fundamental idea of response theory, namely, the calculation of field-induced molecular properties through changes in expectation values, is explained in a manner equally valid for approximate wave function and density func

The goal of this chapter is to describe recent developments in the theory of intermolecular interactions that ha

Here, we have review some of the models and techniques that have been employed to study force-induced transitions in biopolymers. We briefly describe the merit and limitation of these models and technique
