High Energy Theory Seminar

Goldstone Gauginos
Neal Weiner
2:30pm|Bloomberg Lecture Hall
Experimental constraints on models such as supersymmetry have challenged our assumptions about naturalness, while simultaneously pushing exploration into alternatives that might be more natural. One such scenario is supersymmetry with Dirac...

Non-thermal Dark Matter -- a Generic Prediction of String/M theory
Bobby Acharya
2:30pm|Bloomberg Lecture Hall
Solutions of string/M theory with low energy supersymmetry breaking generically have light moduli fields whose masses are of order the supersymmetry breaking scale. These fields -- whose expectation values parametrise the size and shape of the...

High Energy Theory Seminar

Exact Holographic Mapping, Tensor Networks and Space-time Geometry
Xiaoliang Qi
2:30pm|Bloomberg Lecture Hall

Holographic duality is a duality between gravitational systems and non-gravitational systems. In this talk, I will propose a different approach for understanding holographic duality named as the exact holographic mapping. The key idea of this...

High Energy Theory Seminar

The Time Reversal Invariant Fractional Josephson Effect
Charles Kane
2:30pm|Bloomberg Lecture Hall

Topological Superconductivity is a topic of current interest because of its potential for providing a new method for storing and manipulating quantum information. One of the most basic consequences of topological superconductivity is the fractional...

Quantum Supergravity and Exact Holography
Joao Gomes
2:30pm|Bloomberg Lecture Hall

I will present recent results on the computation of finite N corrections in supergravity in the context of AdS2/CFT1 and AdS4/ABJM holography. I will show how to use localisation in supergravity to compute all perturbative and nonperturbative charge...
