Many-body Theory Calculations of Positron Binding to Halogenated Hydrocarbons

J. P. Cassidy, J. Hofierka, B. Cunningham +3

Positron binding energies in halogenated hydrocarbons are calculated \emph{ab initio} using many-body theory. For chlorinated molecules, including planars for which the interaction…

Many-body theory of positron binding in polyatomic molecules

J. Hofierka, B. Cunningham, C. M. Rawlins +2

Positrons bind to molecules leading to vibrational excitation and spectacularly enhanced annihilation. Whilst positron binding energies have been measured via resonant annihilation…

Magnetic defects promote ferromagnetism in Zn1-xCoxO

Charles H. Patterson

Experimental studies of Zn1-xCoxO as thin films or nanocrystals have found ferromagnetism and Curie temperatures above room temperature and that p- or n-type doping of Zn1-xCoxO ca…

Band structures of rare gas solids within the GW approximation

S. Galamić-Mulaomerović, C. H. Patterson

Band structures for solid rare gases (Ne, Ar) have been calculated using the GW approximation. All electron and pseudopotential ab initio calculations were performed using Gaussian…
