Theory Seminar: Yu Nakayama

Surprising trace anomaly from freakolography

Mon. Mar. 19 @ 12:00 PM

Room CP 179

ABSTRACT

One of the myths in theoretical physics is that in four-dimension, the trace anomaly is given only by the central charges "a" and "c". I'd like to discuss other possibilities e.g. R2 term and Hirzebruch-Pontryagin density. In particular, I'll show how these can arise in a ``freakolographic computation". Are they really consistent? Any pathology? I'd like to challenge how far the holograhic computation can go. The obvious but sutble distinction between scale invariance and conformal invariane will be emphasized.

WIRED Living Learning Community

Incoming Freshman are encouraged to apply to live in UK's A&S Wired dormitory located in Keeneland Hall. A&S Wired features a technology-infused curriculum designed around the concept of a 21st century liberal arts education. Students take 2-3 of the same courses, including eight-week interdisciplinary Wired courses and a first-year writing course, as part of a shared academic program that promotes communal learning.

What's New in Science - Ganpathy Murthy Part 2

Ganpathy Murthy, Professor of Physics and Astronomy, speaks about Big Bang Theory, Dark Matter and Dark Energy. Part 2 - What’s the Evidence for the Big Bang and Expansion of the Universe? What Do We Measure and How? What’s the evidence? How we know the Big Bang happened, and that the universe is expanding and accelerating. How we measure how fast different parts of the Universe are moving away.
