In a surprising discovery, Princeton physicists have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum oscillation, is typically observed in metals rather than insulators, and its discovery offers new insights into our understanding of the quantum world. The findings also hint at the existence of an entirely new type of quantum particle.
The Cleland and Schuster groups at the University of Chicago have demonstrated multi-bit entanglement in a Quantum Network.
The Gardel lab at the University of Chicago has realized an active liquid crystal where the active stresses could be modulated spatiotemporally through selective illumination with blue light.
Semiconductors, which have electrical properties in between metals and insulators, are the building blocks of devices like transistors that fuel computer technology. New semiconducting materials that could outperform existing ones are continuously sought in science and engineering, with oxides being one contender.
Screening block oligomer chemistry and architecture through molecular simulations to find promising candidates for functional materials requires effective morphology identification techniques. Common strategies for structure identification include structure factors and order parameters, but these fail to identify imperfect structures in simulations with incorrect system sizes.
Trained binding interactions can assemble multiple distinct structures from a soup of molecules through distinct nucleation pathways.
MRSEC faculty at Princeton University and the University of Delaware co-hosted a virtual symposium celebrating early-career researchers in Soft and Biological Matter with a focus on those from underrepresented groups.
PAQM researcher Theanne Schiros creatied a virtual exhibition entitled 6878 KM. The exhibition features outreach and international sustainable development teaching natural dye chemistry to artisans, especially women, in ultra-poor communities in West Africa.
Active control over exciton (electron-hole pair) transport is a much sought-after goal to create reconfigurable excitonic and optoelectronic transistors. The PAQM team achieved the first example of predictive optical control over exciton transport in semiconductors.
Researchers have developed programmable DNA origami building blocks that self-assemble into icosahedral shells, with programmable sizes. The shells can be functionalized with antibodies, enabling them to engulf and neutralize natural viruses.
