From the Yodh Group: Drops of liquid crystal molecules branch out into strange structures

Shaped by surface tension and elasticity, spherical drops of chain-like liquid crystal molecules transform upon cooling into complex shapes with long-reaching tendrils.

Penn Researchers create better light-trapping devices

A new study shows how the performance of optical resonators can be improved using topological physics, which can lead to more efficient lasers, sensors, and telecommunication devices.


Penn physicists look to navigational ‘rhumb lines’ to study polymer’s unique spindle structure

Researchers show how polymer spheres contract to form unique spiral structures known as loxodromes, or rhumb lines, creating patterns that are ten times smaller than the width of a human hair.






Liang Wu has received the William L. McMillan Award, Forbes 30 Under 30

Liang Wu, assistant professor of physics and astronomy in the Penn School of Arts and Sciences, has received the 2019 William L. McMillan Award from the department of physics at the University of Illinois for his outstanding contributions in condensed matter physics. This award, which Dr. Wu will share with Barry Bradlyn of the University of Illinois, is presented annually to a condensed matter physicist for distinguished research performed within five years of receiving a PhD. Dr.

Penn physicist Doug Durian is chair of a new division of the American Physical Society, DSOFT

Penn has one of the strongest soft matter groups in the world, with many high-profile faculty in the School of Arts and Sciences, particularly Physics & Astronomy, as well as the School of Engineering and Applied Science.

Assistant Professor in Experimental Soft Matter Physics

The Department of Physics and Astronomy at the University of Pennsylvania seeks applications from outstanding candidates for an appointment as Assistant Professor in experimental soft matter physics, broadly defined. The successful candidate will develop an innovative research program that attracts the participation of students and creates collaborative links with other Penn scientists and engineers. The candidate should have a Ph.D.
