The Princeton MRSEC has leveraged the low disorder and long coherence of states in a pristine silicon crystal to experimentally realize the Tavis-Cummings model, a fundamental model in quantum optics.

The Princeton MRSEC has detected a unique quantum property of an elusive particle, the Majorana fermion that is notable for behaving simultaneously like matter and antimatter. Using enhanced scanning tunneling microscopy techniques, the team captured signals from the Majorana particle at both ends of an atomically thin iron wire stretched on the surface of a crystal of lead.
Inspired by the human eye, a team led by Clarke at the Harvard MRSEC has reported in Science Advances an adaptive metalens that is a flat, electronically-controlled artificial eye. This new lens which combines breakthroughs in artificial muscle and lens technologies simultaneously controls focus, astigmatism, and image shift.
Crushing a soda can from top to bottom is easier if it is dented initially on the side. Predicting the force needed to crush a dented can, however, which is of critical importance for structural reliance of materials engineering is quite challenging.
Limited performance and reliability of electronic devices at extreme temperatures, intensive radiation found in space exploration missions and earth-based applications requires the development of alternative computing technologies. Nebraska MRSEC researchers have designed and prototyped the world’s first high-temperature thermal diode.
In Summer 2017, Nebraska MRSEC partnered with the Foundation for Lincoln Public Schools to offer a new, STEAM-based summer learning program. Spark Summer Learning provides opportunities for students in grades K-5 to explore science, technology, engineering, art, and math in an immersive setting, engaging students in problem-based learning through hands-on “maker” projects.
Switchable electric polarization of ferroelectric materials can serve as a state variable in advanced electronic systems, such as non-volatile memories and logic. Control of ferroelectric polarization by external stimuli is the key component for these systems.
Multiferroics is a class of materials that exhibits a coexistence of electric and magnetic polarizations. Coupling of these polarizations is potentially useful for energy-efficient information storage and processing. Hexagonal rare-earth ferrites (h-RFeO3, where R is rare-earth element and Fe is iron) are new family of multiferroic materials.
