  abstract     = {{Electron-lattice interactions play a large role in determining physical properties of crystalline solids, such as electrical resistance and superconductivity. Properties like these are not only of theoretical interest, but also of practical importance when designing new materials. A key quantity describing these interactions is the electron-phonon coupling, which links atomic displacement to changes in the electronic free energy and the resulting lattice forces. This thesis investigates the interatomic force constants emerging from the electron-phonon coupling in a two-dimensional square lattice, within a tight-binding framework. By introducing a distance-dependent hopping parameter, mobile electrons couple to the lattice and the resulting forces can be derived from the electronic structure. The force constants are defined as the second derivative of the Helmholtz free energy of the electronic Hamiltonian. An analysis is given of how variables such as temperature, chemical potential, hopping strength and atomic displacement affects the force constants. Finally, the strength and limitations of this approach to electron-lattice coupling are discussed.}},
