Clifford Johnson Colloquium: Holographic Heat Engines for Fun and Profit

April 11, 2018

Clifford Johnson is a theoretic physicist at the University of Southern California, who focuses on string theory and gravity. He is a gifted speaker, science advisor for television and movies, and the author of a non-fiction graphic novel Dialogues: Conversations about the Nature of the Universe. He will give a talk on April 11, 2018 at 4pm in Chapman Hall Room 201 on the campus of UNC Chapel Hill.

Colloquium: Holographic Heat Engines for Fun and Profit

New work has shown how to complete the correspondence between the physics of black holes and the laws of thermodynamics by incorporating volume and pressure into the formalism. This results in a change in the thermodynamic interpretation of the black hole’s mass, and may give a new handle on understanding aspects of theories of gravity with non-vanishing cosmological constant. The concept of the “holographic heat engine”, where a black hole acts as the working substance for a heat engine, arises naturally in this framework, and further connects ideas from traditional thermodynamics, quantum gravity, and field theory. This talk will try to motivate and explain some of these developments and show some potential applications.

 

Black Holes, Time, and Space with Clifford Johnson

April 10, 2018

Dr. Clifford Johnson, professor of physics & astronomy at the University of Southern California, will take us on a whirlwind tour of Black Holes, Space & Time while sharing his experiences as a science adviser to television and movies, including Marvel superhero movies. His graphic novel Dialogues: Conversations about the Nature of the Universe, will be available for sale with a book signing following questions and answers. The event will take place April 10 starting at 5:30 at the Morehead Planetarium and Science Center.

Abstract:   New work has shown how to complete the correspondence between the physics of black holes and the laws of thermodynamics by incorporating volume and pressure into the formalism. This results in a change in the thermodynamic interpretation of the black hole’s mass, and may give a new handle on understanding aspects of theories of gravity with non-vanishing cosmological constant.

Astronomy on Tap: The End of the World and Finding New Worlds with Tiny Telescopes

March 6, 2018

Astronomy on Tap will have its next event on March 6th at Fullsteam Brewery in Durham, led by 2 CoSMS members.

  • Dr. Chris Clemens (UNC-CH) will discuss all the ways the world can end.
  • Dr. Nick Law (UNC-CH) will talk about how to find extrasolar planets with tiny telescopes.

Astronomy on Tap events are meant to provide a venue for short outreach talks (~20 min with plenty of time for questions) in a relaxed setting over beers — they are free, open to all ages, and start at 7 pm. Some more details about the event can be found at the link here:

Astronomy on Tap: The Beginning and End of the Universe

February 6, 2018

The first Astronomy on Tap event of 2018 at Fullsteam Brewery in Durham is focused on cosmology and the beginning and end of our Universe and led by 2 CoSMS members.

  • Dr. Adrienne Erickcek (UNC-CH) will discuss the hot big bang and our expanding Universe.
  • Dr. Katie Mack (NCSU) (http://www.astrokatie.com/) will talk about the future of the cosmos and how the Universe will likely come to an end. She also has a very large following on social media: https://twitter.com/AstroKatie

20th Capra Meeting on Radiation Reaction in General Relativity

June 19, 2017

The Capra meetings have been bringing together relativists interested in the problem of radiation reaction in general relativity and its application to extreme-mass-ratio inspirals (EMRIs) as astrophysical sources of gravitational waves. The meeting will be held June 19-23, 2017 at UNC.

Three Seeds in the Flowering of Quantum Science

April 10, 2017

Prof. Daniel Kleppner from the Massachusetts Institute of Technology and recipient of the 2017 APS Medal for Exceptional Achievement in Research, will present a talk entitled “Three Seeds in the Flowering of Quantum Science.”

A new field of quantum science has sprung into life in the last few decades. This talk will describe three of the scientific seeds that contributed to this flowering.

A reception will be held outside of Chapman 201 after the colloquium.
