A Multidisciplinary Investigation on the Influence of Archean Seawater Composition and UV radiation levels on the Survival and Evolution of Early Microorganisms
DownloadFall 2014
Life evolved in the oceans nearly four billion years ago, but the environmental conditions surrounding its evolution remains poorly understood. While Archean seawater (2.5 to 3.8 Ga) provided ancient microorganisms with the bioactive trace metals needed to sustain their metabolic requirements, it...

The conventional, single band Hubbard model captures the dynamics that arise in strongly correlated electron systems in the competition between electron transport and local Coulomb interactions. However, some of the important physics of real lattices is overlooked by its simplicity. The dynamic...
