Today's Seminar

    2.00 pm, Lecture Hall 803
    Time-dependent NAdS2 holography with applications
    Alexander Soloviev
    University of Vienna.
    Abstract
    NAdS2 holography has recently been studied extensively as a tool to explore many interesting fundamental questions. In this vein, we develop a method for obtaining exact time-dependent solutions in Jackiw-Teitelboim gravity coupled to non-conformal matter and study consequences for NAdS2 holography. The resulting effective 0+1 dimensional description describes trapped impurities confined to a spatial point. We discuss that our model will be able to describe di-quarks in the quark-gluon plasma after inclusion of some additional features.
