Extended Hubbard Model realized in 2D clusters of molecular anions
Oliver Tong, Katherine A. Cochrane, Bingkai Yuan +3
The Hubbard model, despite its simplicity, is remarkably successful at describing numerous many-body phenomena. However, due to the small class of problems which can be solved exac…

Intrinsic defect intolerance in the ultra-pure metal PtSn
Samikshya Sahu, Dong Chen, Niclas Heinsdorf +6
Ultra-pure materials are highly valued as model systems for the study of intrinsic physics. Frequently, however, the crystal growth of such pristine samples requires significant op…

Quenching of excitons at grain boundaries in C60 thin films
Rysa Greenwood, Bradley G. Guislain, MengXing Na +12
Exciton lifetimes play a critical role in the performance of organic optoelectronic devices. In this work, we investigate how the presence of multiple rotational domains, and there…
