Effective Symmetries: Clues to Higher Dimensions

3:30 PM
"Effective Symmetries: Clues to Higher Dimensions”
Dr Tristan Hubsch
D. Physics and Astronomy, Howard University.

ABSTRACT: Many of the well-known physical models exhibit symmetries that have
not been built into them by the initial construction and application.
Such "effective" symmetries often help understanding both the model
as well as the physical system being modeled by it. After a cursory
survey of a few simple cases, I will describe how such effective
symmetries---well-nigh holographically---remember whether a quantum-
mechanical supersymmetric system is a "dimensionally reduced" shadow
of a system defined in a higher-dimensional spacetime.

Temporary Physics Faculty Position

The Department of Physics and Astronomy anticipates filling two temporary (non tenure-track) faculty positions for two semesters (spring and fall semesters) starting January 2015, subject to budgetary approval. Applicants are invited in all areas of physics.

These position are for the rank of Lecturer/Instructor with primary responsibility for instruction, require a PhD degree in physics or a closely related field and a strong commitment to excellence in teaching.

Review of applicants will begin on October 15, 2014 and continue until the positions are filled. Application materials should include a letter of application, a curriculum vitae, and names and contact information (e-mail address and telephone) of three references. Although electronic applications are preferred (, the application materials may also be sent to:

Chair, APT Committee
