R. G. Herb Condensed Matter Seminar
Enhancing cavity QED via anti-squeezing: synthetic ultra-strong coupling and entangled cat-states
Time: 10:00 am
Place: 5310 Chamberlin Hall
Speaker: Dr. Luke Govia, University of Chicago
Abstract: We present applications of parametric (two-photon) driving of a cavity in a generic cavity QED setup, which can be used to exponentially enhance the light-matter coupling. This can take a weakly coupled system into the strong coupling regime (where the coupling exceeds dissipative rates) and even the ultra-strong coupling regime (where the coupling is comparable to the cavity frequency). As an example, we show how this allows one to use a weak-coupling system to adiabatically prepare the highly entangled ground state of the ultra-strong coupling system. Furthermore, we show that by adding local Kerr nonlinearities to parametrically driven cavities one can stabilize an entangled cat-state between the cavities.

Astronomy Colloquium
"Simulations of Black hole Accretion and Outflows"
Time: 3:30 pm
Place: 4421 Stering Hall, Coffee and cookies 3:30 pm, Talk begins at 3:45 pm
Speaker: Alexander Tchekhocvskoy, Northwestern University
Abstract:
Black holes are responsible for a wide variety of astrophysical phenomena. They devour stars, eject relativistic jets, affect star formation and galaxy evolution, and enrich the Universe with heavy elements. I will discuss how global general relativistic magnetized fluid dynamics numerical simulations allow us to use this activity to quantitatively probe strong-field gravity and constrain black hole physics in various astrophysical context
