Bio

Dr. Lucas Caretta is a University of California President’s Postdoctoral Fellow and a Ford Foundation Postdoctoral Fellow at UC, Berkeley working with Professor Ramamoorthy Ramesh. Caretta completed his Ph.D. in Materials Science and Engineering at the Massachusetts Institute of Technology under the supervision of Professor Geoffrey Beach. There, he made significant contributions to the understanding of magnetic soliton dynamics in compensated systems. His current research interests focus on developing new material systems and in-situ techniques to manipulate ferroic excitations and dynamics in nanoscale thin films.

Research

One of the most promising prospects in magnetism and ferroelectricity is the ability to control the magnetic and charge state of a material using electrical and optical stimuli. Not only does this have great technological implications, but also provides an arena to investigate new, fundamental physical phenomena, such as topology, chirality, and even relativity. Studying these phenomena requires electrical and optical probes that push experimental limits to the fastest timescales, the smallest length scales, and highest sensitivities. Much of Caretta’s work is dedicated to improving these techniques and synthesizing new materials to help push ferroic research, and its technology, further.
