Multi-step approach to microscopic models for frustrated quantum magnets - the case of the natural mineral azurite
Harald Jeschke, Ingo Opahle, Hem Kandpal +14
The natural mineral azurite Cu(CO)(OH) is a frustrated magnet displaying unusual and controversially discussed magnetic behavior. Motivated by the lack of a unified…
Piezoelectrics by Design: A Route through Short-period Perovskite Superlattices
Hena Das, Umesh V. Waghmare, T. Saha-Dasgupta
Using first-principles density functional theory, we study piezoelectricity in short-period superlattices made with combination of ferroelectric and paraelectric components and exh…
Chemical control of polar behavior in bicomponent short-period superlattices
Hena Das, Nicola A. Spaldin, Umesh V. Waghmare +1
Using first-principles density functional calculations, we study the interplay of ferroelectricity and polar discontinuities in a range of 1-1 oxide superlattices, built out of fer…
