The research fields of physics department include particle physics, astrophysics and general relativity, accelerator physics, condensed matter physics and biophysics.

Condensed matter physics is a large group, and its research directions include: non-equilibrium system principle, complex fluids and polymers, critical phenomena and phase transitions, nanostructures, low-temperature physics, quantum fluctuations and entanglement, ultracold atoms, etc. David M. Lee and Professor Robert C. Richardson jointly won the Nobel Prize in Physics in 1996.

In addition, the research of particle physics is also very powerful. Directions include elementary particles, CP symmetry breaking, basic model, strong interaction, weak interaction, quark properties and so on.

Cornell University also has applied physics programs, which are independent from the Department of Physics, with relatively new and cutting-edge research directions, including nano-science and technology, photonics and quantum electronics, condensed matter and material physics, biophysics, plasma physics, atomic and molecular physics and so on. The application deadline is 1. 15, and the requirement for TOEFL is PBT & gt=550.
