Dear quanta, Here is a field-theory talk that uses quantum information to get some physical constraints. I'm not sure what the speaker means by 'quantum information' but I know that strong subadditivty has been used in similar settings. ---------- Forwarded message ---------- From: Nicole Amanda Laraia &lt;ndillie(a)mit.edu&gt; Date: Thu, Nov 2, 2017 at 3:59 PM Subject: [Lnsfaculty] [Lns-seminars] Nuclear and Particle Physics Colloquium Monday, November 6 To: [image: cid:945F1333-452E-4BB0-994E-E815014C1458] *Nuclear and Particle Physics Colloquium (NPPC)* *Monday, November 6,** 2017* 4:00 PM Kolker Room (26-414) *(refreshments served at 3:30PM)* *Bounding Negative Energy Density with Causality and Quantum Information* *Tom Faulkner— University of Illinois* *Abstract:* Negative energy density can arise naturally in Quantum Field Theory. However too much of it can lead to pathological spacetimes when coupling the theory to gravity. In this talk I will discuss conjectured bounds on negative energy density and sketch very recent general proofs of these bounds. The methods we use combine causality considerations with concepts taken from quantum information theory. http://web.mit.edu/lns/news/n <http://web.mit.edu/lns/news/nuclear.html>u clear.html <http://web.mit.edu/lns/news/nuclear.html> _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip
