Local integrals of motion in the two-site Anderson-Hubbard model
R. Wortis, Malcolm P. Kennett
It has been proposed that the states of fully many-body localized systems can be described in terms of conserved local pseudospins. Due to the multitude of ways to define these, th…
Influence of the ferroelectric quantum critical point on SrTiO interfaces
W. A. Atkinson, P. Lafleur, A. Raslan
We study a model SrTiO interface in which conduction electrons couple to the ferroelectric (FE) phonon mode. We treat the FE mode within a self-consistent phonon theor…
Temperature-Dependent Band Structure of SrTiO Interfaces
Amany Raslan, Patrick Lafleur, W. A. Atkinson
We build a theoretical model for the electronic properties of the two-dimensional (2D) electron gas that forms at the interface between insulating SrTiO and a number of polar c…
Persistence of energy-dependent localization in the Anderson-Hubbard model with increasing system size and doping
P. Daley, R. Wortis
Non-interacting systems with bounded disorder have been shown to exhibit sharp density of states peaks at the band edge which coincide with an energy range of abruptly suppressed l…
