Hawking Radiation and Useful Neutrinos
Today I’ve seen two interesting works:
First is from my advisor Wilczek and my friend Mr. Robinson. After Frank's long rush time for obvious reasons their paper is finally on ArXiv: gr-qc/0502074. They are considering an effective field theory around a black hole horizon. They show that to cancel the anomalies that break general covariance, black hole must sit in a thermal radiation bath exactly at the Hawking temperature. It is a brand new way of proving Hawking radiation with lots of physical insight. Well done, Sean! We will soon congratulate you for your graduation ;)
Finally somebody found a use for neutrinos! If you can make a vertical beam line, you can probe Earth's interior density distribution with incredible accuracy from neutrino oscillations. Idea is due to Walter Winter of Advanced Study. See hep-ph/0502097 and PhysicsWeb coverage.
