That's Not How We Do It Here! : A Story About How Organizations Rise, Fall - and Can Rise Again /
Published 2016“…In their iconic bestseller Our Iceberg Is Melting, John Kotter and Holger Rathgeber used a simple fable about penguins to explain the process of lead­ing people through major changes. Now, ten years later, they're back with another must-read story that will help any team or organization cope with their biggest challenges and turn them into exciting opportunities. …”

Emergent vortices at a ferromagnetic superconducting oxide interface
Published 2014“…This hysteresis is argued to arise from vortex depinning within a thin (< 20 nm) superconducting layer, mediated by discrete ferromagnetic dipoles located solely above the layer. The pinning strength may be modified by varying the superconducting channel thickness via electric field-effect doping. …”
