String Theory seminar - Olga Papadoulaki Seminar

In this talk, I will give an overview of the work I did during my PhD and what I am currently working on. I will start by presenting a description of Gerard 't Hooft's black hole S-matrix using a collection of inverted harmonic oscillators. Then I will give a very brief overview on how and why we are trying to compute the 1-loop corrections to a wormhole solution. In the second part, I will present an S^1/Z_2 orbifold in Liouville string theory through a dual matrix quantum mechanics description and I will explain how we performed a matching on the two sides of the duality. In the same context, I will give a brief overview on my current work that involves coupling to the gauged matrix quantum mechanics model fundamental and anti-fundamental fields. Finally, I will present how we modelled a quantum critical point in a 2+1 dimensional system at finite charge density under constant external magnetic field using applied holography.
