# Advanced seminar on Geometry, Topology and Physics to be offered in 2016-17 academic year

**May 16, 2016
- CHTM**

*Dr. Arash Mafi*

Arash Mafi, PhD, General Chair, Optical Science and Engineering; Associate Professor, Department of Physics & Astronomy; and Faculty Member, Center for High Technology Materials, together with Rouzbeh Allahverdi, PhD, Associate Professor, Department of Physics & Astronomy, said the seminar should be viewed as a forum for collaborative study of the subject, and everyone is most welcome to participate and contribute.

The seminar emerged from their discussions on mutual research interests. The topic was chosen for its broad applications in topics such as general relativity, the Aharonov-Bohm effect and Berry's phase, quantum Hall effect, instantons and monopoles, cosmic strings, liquid crystals, topological insulators, topological photonics and optical isolators, and others.

The main textbook will be: "**Geometry, Topology, and Physics**, 2nd Ed." by *Mikio Nakahara*. It is available at: http://www.amazon.com/Geometry-Topology-Physics-Graduate-Student/dp/0750306068

*Dr. Rouzbeh Allahverdi*

This is a highly regarded book and covers the mathematical foundations without overburdening the reader with unnecessary formalism. Because the book is intended for physicists, the flow provides a familiar tone that can be readily grasped by advanced undergraduate and beginning graduate students. Please see below for a tentative syllabus for two semesters. This will likely be a fast-paced seminar to cover the proposed material and will require considerable independent reading through the text.
