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).

Researchers suggest novel way to generate a light source made from entangled photons

PHYS.ORG — Entanglement is a strange phenomenon in quantum physics where two particles are inherently connected to each other no matter the distance between them. When one is measured, the other measurement is instantly a given. Researchers from Purdue University have proposed a novel, unconventional approach to generate a special light source made up of entangled photons. On Sept. 6, 2022, they published their findings in Physical Review Research.

Promoting STEM across the world and to all ages

Purdue’s Department of Physics and Astronomy’s K-12 outreach programs have a great breadth and depth, and in the past 10 years have offered a wide range of opportunities for students of all ages. David Sederberg, the department’s outreach coordinator, has brought the joy of STEM and the name of Purdue into the hearts and aspirations of young students and attracted a community of learners and trainers both at Purdue and beyond.

Eighteen Faculty at Purdue University Recognized for Early Career Success

Eighteen Purdue University assistant and associate professors received National Science Foundation Faculty Early Career Development (CAREER) Awards in fiscal year 2022 to fund research from sensorized farms to quantum networks at the world-renowned, public research university. Ruichao (Alex) Ma, assistant professor of physics and astronomy, was awarded for Synthetic Quantum Materials in Superconducting Circuits.

Duo of Purdue Professors Awarded NSF Grant

A pair of Purdue professors, in collaboration with peers from the University of Wyoming, have been awarded a grant of $5 million by the National Science Foundation for their research in the area of quantum information science and engineering. Dr. Yong P. Chen, of Physics and Astronomy, along with Dr. Gary Cheng, from the School of Industrial Engineering are both co-principal investigators of the project, titled “ExpandQISE: Track 2: Developing Research and Education Programs in Quantum Information Science and Engineering with Research on Locally Tunable 2D Topological Superconductors”
