Condensed Matter Theory Group Meetings: Lent 19/20
This term’s meetings will take place at 11am on Thursdays. This term will start off with a seminar and continue with a series of dice seminars on the topic of SYK and gravity.
Dice Seminars: Sometimes we run Dice Seminars, which occur over the course of 5 weeks or so, and consist of us collaboratively learning about a given topic, by reading a paper or paper section, and rolling a dice to determine who will talk about what they’ve read. The previous topic was “Machine Learning”. The topic before that was “Topological Insulators”.
Other Meetings: There are ~weekly condensed matter seminars at 3pm on Fridays, which will be interesting for anyone attending our group meetings. These are advertised internally.
Mailing List: If you would like to be added to the mailing list for these meetings, please subscribe.

Hamed Ghaemidizicheh – Physics of Nonlinear Spectral Singularity
Spectral singularities are specific points of continuous spectrum of complex scattering potentials where the transmission and reflection amplitudes diverge. This mathematical concept was initially introduced by mathematicians and has recently paved its way in physics. In this presentation, I review the nonlinear generalization of spectral singularity and its application in Optics.
