Cornell researchers have demonstrated that acoustic sound waves can be used to control the motion of an electron as it orbits a lattice defect in a diamond, a technique that can potentially improve the sensitivity of quantum sensors and be used in other quantum devices.

Using a combination of machine learning and powerful X-rays, Cornell researchers have solved a mystery behind the unusual behavior seen in a class of materials with potential for thermoelectric energy conversion and other applications.

A research team led by Cornell mapped atomic vibrations in diamond and linked them with the behavior of the quantum system embedded within, an advance that will make quantum sensors significantly more precise than today’s detection tools.

A team led by Judy Cha collaborated with the late Lena Kourkoutis to use cryo-electron imaging to study how defects in the microstructure of the nanomaterial tantalum disulfide affects its properties.

A supercrystal formation previously unobserved in the thin-film Mott insulator Ca2RuO4 was discovered by a Cornell-led research team, potentially unlocking new ways to engineer materials and devices with tunable electronic properties.

A Cornell-led team used ultrafast laser spectroscopy to scrutinize a key intermediate state during singlet fission and found that in certain molecules the intermediate can be directly generated with a strikingly simple technique.

With pulses of sound through tiny speakers, Cornell physics researchers have clarified the basic nature of the newly discovered superconductor uranium ditelluride.

Karan Mehta, assistant professor of electrical and computer engineering in Cornell Engineering, is one of six Cornell researchers who recently received National Science Foundation Faculty Early Career Development Awards. Mehta’s award supports his group’s investigations of ion-light interaction in tailored spatial field profiles, in which fine spatial variations of the field profile can potentially enhance basic operations relevant for quantum computation and atomic clocks.
