• From Einstein's Legacy to Hawking's Cosmos

 This course is designed for those undergraduates who are interested in modern physics as well as its recent  developments   no matter who is majoring in physics or not.  In particular, I intend to convey relativity and its modern implications from     gravitational waves, cosmology, black holes, all the way to extra dimensions, strings, branes, and holographic principle in   a clear, logical manner, without oversimplification and without inclusion of irrelevant technical details. In passing, the   basic concepts of other branches of physics, such as quantum mechanics and thermodynamics,  are also be conveyed in an   appropriate place.

• Quantum Field Theory in Curved Spacetime

This course is designed for those who aspire to work on quantum gravity. As such, different from the quantum field theory course for both particle physics and condensed matter physics, not only is the prerequisite differential geometry and general relativity, but also the emphasis is on the conceptual issues rather than on the computational ones. With this, the students are expected to be well prepared to work on a variety of issues in the frontiers of fundamental physics.

• Applied String Theory

The content of this course varies year by year, as it includes some special topics selected from the state of the art in fundamental physics, of which we should be aware. If we are lucky, some of them may emerge as our own research directions.  The topic for 2021 Spring semester will be the triangle relation among asymptotic symmetries, memory effects, and soft theorems.
