Lifshitz Solutions in String and M-Theory
📍 London
Aristomenis Donos
(Imperial)
Abstract:
Condensed matter systems at quantum critical points can be described by strongly coupled field theories exhibiting anisotropic scale invariance. Lifshitz geometries been proposed to be holographic duals to these theories. I will discuss top down constructions of Lifshitz geometries in Type IIB and D=11 dimensional supergravities.

Skyrmions, instantons and holography
Paul Sutcliffe
(Durham)
Abstract:
Recently the Skyrme model has been derived from string theory in
the context of holographic QCD. Inspired by this work, I shall
introduce a BPS Skyrme model derived from Yang-Mills theory.
This explains and extends the construction of Skyrmions from the
holonomy of Yang-Mills instantons, introduced some time ago by
Atiyah and Manton

F-enomenology
📍 London
Sakura Schafer-Nameki
(King's)
Abstract:
I will give an overview of recent developments in F-theory GUT
model building. First I will discuss the basic ideas of F-theory model
building, exemplifying this by the construction of supersymmetric SU(5)
GUTs. Then I will outline how global string theoretic consistency
requirements impact the SUSY phenomenology. The main focus of this talk
will be on the phenomenological implications of these models.

Constraining F-theory GUTs
Sakura Schafer-Nameki
(King's)
Abstract:
String theory phenomenology generically suffers from either too much flexibility (and lack of predictability) or from the a high specialization to case by case studies. I will discuss how F-theory GUT model building manages to get around these pitfall, in particular, I will explain, how to systematically include global string consistency conditions, which are independent of the specific compactification, and which come with the benefit of highly constraining the class of GUT models that can arise from F-theory.
