Responsive and adaptive particles display a broad and sometimes polymodal spectrum of internal (monomeric) distributions and have thus the ability to change their properties (such as size, shape, charge density, etc.) easily in response to external fields or to their local (cosolute) environment. In this course we discuss the basic statistical mechanics for liquids of adaptive particles (APs) and argue that in the thermodynamic limit the system behaves like conventional polydisperse systems with continuous polydispersity distributions. We then focus on the aspect that in the presence of external fields APs have local (position-dependent) properties which impose local pair potentials and non-trivial effects on the one- and two-body property and number density distributions, even for an ideal (non-interacting) gas of APs. We finally employ classical density functional theory in the local density approximation (LDA-DFT) to discuss the effects of position-dependent properties explicitly for simple selected examples of inhomogeneous AP liquids in external fields.
