Alexander Croy

Forskare at Chalmers, Physics, Condensed Matter Theory

I am currently working in the group of Prof. Jari Kinaret at Chalmers University of Technology as a postdoctoral researcher. The focus of my current research activities is on graphene based (mechanical) reso-nators and quantum electro-mechanical systems. I am also interested in time-resolved electron transport in nano-devices with applications to non-adiabatic electron pumping and in questions related to Anderson localization.
