Abstract
Many-body localisation is a phenomenon in interacting, disordered systems and is a robust way of avoiding thermalisation. It has a number of interesting physical properties includ- ing giving rise to a finite-temperature insulating state as well as logarithmic entanglement growth with time. Although experimental progress has been made in systems of ultracold atoms due to isolation from the environment being possible, there have been limited de- velopments in solid-state systems where the presence of phonons restores transport and destroys localisation. This work focuses on identifying signatures of (i) electron-phonon decoupling in suspended thin films and (ii) the absence of thermalisation in quantum dots. Both tasks will allow for experimental progress in identifying electronic systems that are suitable for trying to observe many-body localisation.
