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).

World Cancer Research Day: Animated Dynamics predicts a cancer drug’s effectiveness

Today, September 24, is World Cancer Research Day. We are pleased to feature Animated Dynamics on The Line. The company, which licenses technology through the Purdue Research Foundation Office of Technology Commercialization, helps improve the results of personalized cancer care. Researchers can use the technology to determine how a specific tumor will respond to chemotherapy even before a patient begins treatment.

A quest for symmetry: Purdue physicists discover symmetry in the Wigner solid

An exciting and expanding branch of physics research involves topological properties in electronic systems. The physics community has placed particularly large efforts on investigating topological properties which involve electron-electron interaction. There is an ongoing quest to see if two-dimensional topological matter displays a fundamental link, or symmetry, between the stability regions of the electronic phases. This symmetry is commonly referred to by physicists as “particle-hole symmetry.” According to Gábor Csáthy, Professor and Interim Head at Purdue University Department of Physics and Astronomy, particle-hole symmetry was already discovered and known in the fractional quantum Hall regime, but his lab has recently published “Particle-hole symmetry and the reentrant integer quantum Hall Wigner solid” in Communications Physics in which they have discovered that this symmetry also applies to the Wigner solid.

Researchers use gold film to enhance quantum sensing with qubits in a 2D material

A team of researchers at Purdue University took on the challenge of overcoming qubit signal shortcomings in their work to develop ultrathin quantum sensors with 2D materials. Their publication in Nano Letters demonstrates that they have solved some of the critical issues and yielded better results through experimentation.

An unexpected result allows researchers to narrow the scope on the quest for the chiral magnetic effect

A long-awaited quest for the “chiral magnetic effect (CME),” which could explain the dominance of matter over antimatter in our universe, has been released after years of research with the Relativistic Heavy Ion Collider (RHIC), of the U.S. Department of Energy (DOE). This experiment took place over multiple locations, including Purdue University, and sought to discover evidence of the CME.

Taking Purdue Gold to a whole new level

A team of researchers at Purdue took on the challenge of overcoming qubit signal shortcomings in their work to develop ultrathin quantum sensors with 2D materials. Their publication in Nano Letters was published today, September 2, 2021, and they have solved some of the critical issues and yielded much better results through experimentation.
