Department of Physics and Astronomy

The Department of Physics and Astronomy has a rich and long history dating back to the latter part of the 19th century. Our faculty and students are exploring nature at all length scales, from the subatomic (quarks and gluons) to the macroscopic (black holes and dark energy), and everything in between (atomic and biological systems).

TIME Best Inventions Hall of Fame

TIME — TIME has covered hundreds of inventions, from the esoteric (clouds featured more than once) to essential, including life-changing medicines, technological breakthroughs, new foods, nearly every new Apple product category, and even a few great ideas that didn’t quite catch on. As TIME publishes the 2025 list, we’re also assembling the Best Inventions Hall of Fame: the 25 most iconic inventions we covered in the past quarter century. Both the Large Hadron Collider and the James Webb Space Telescope are among the projects that many Purdue Physics and Astronomy faculty and students have worked on!

James Webb Space Telescope Delivers Stunning Views Of Supernova Remnant Cassiopeia A

Space.com — The James Webb Space Telescope has captured new imagery of supernova remnant Cassiopeia A. It is 11,000 light-years away in the Cassiopeia constellation. Footage courtesy: NASA, ESA, CSA, D. Milisavljevic (Purdue University).

Qi Zhou named American Physical Society Fellow

Qi Zhou, professor in the Physics and Astronomy Department, has been elected as a 2025 American Physical Society (APS) Fellow, a prestigious recognition given to scientists who have made exceptional contributions to physics.

How Purdue University is enhancing education with extended reality

PhysAstro's Danny Milisavljevic and Purdue's Envision Center are transforming education with CollabXR, a Unity-powered XR platform boosting student comprehension. Over 100 students across disciplines benefit from immersive, collaborative learning. This open-source tool is expanding to mobile and desktop AR, redefining education!

Direct evidence of universal anyon tunneling in a chiral Luttinger liquid revealed in edge-mode experiment

Phys.org — Electrons in two-dimensional (2D) systems placed under strong magnetic fields often behave in unique ways, prompting the emergence of so-called fractional quantum Hall liquids. These are exotic states of matter in which electrons behave collectively and form new quasiparticles carrying only a fraction of an electron's charge and obeying unusual quantum statistics.
