Quantum interference in superposed lattices
Yejun Feng, Yishu Wang, T. F. Rosenbaum +2
Charge transport in solids at low temperature reveals a material's mesoscopic properties and structure. Under a magnetic field, Shubnikov-de Haas (SdH) oscillations inform complex…
Origin of two-dimensional electron gases at oxide interfaces: insights from theory
N C Bristowe, Philippe Ghosez, P B Littlewood +1
The response of oxide thin films to polar discontinuities at interfaces and surfaces has generated an enormous activity due to the variety of interesting effects it gives rise to.…
One-dimensional half-metallic interfaces of two-dimensional honeycomb insulators
N. C. Bristowe, Massimiliano Stengel, P. B. Littlewood +2
We study zigzag interfaces between insulating compounds that are isostructural to graphene, specifically II-VI, III-V and IV-IV two-dimensional (2D) honeycomb insulators. We show t…
Proposal of a one-dimensional electron gas in the steps at the LaAlO-SrTiO interface
N. C. Bristowe, T. Fix, M. G. Blamire +2
The two-dimensional electron gas (2DEG) at the interface between LaAlO (LAO) and SrTiO (STO) has become one of the most fascinating and highly-debated oxide systems of rece…
Electrochemical ferroelectric switching: The origin of polarization reversal in ultrathin films
N. C. Bristowe, Massimiliano Stengel, P. B. Littlewood +2
Against expectations, robust switchable ferroelectricity has been recently observed in ultrathin (1 nm) ferroelectric films exposed to air [V. Garcia , Nature {\bf 460},…
Variational discrete variable representation for excitons on a lattice
A. Alvermann, P. B. Littlewood, H. Fehske
We construct numerical basis function sets on a lattice, whose spatial extension is scalable from single lattice sites to the continuum limit. They allow us to compute small and la…
