Spatially Modulated Instabilities of Geometries with Hyperscaling Violation
Sera Cremonini, Annamaria Sinkovics
We perform a study of possible instabilities of the infrared AdS2 x R2 region of solutions to Einstein-Maxwell-dilaton systems which exhibit an intermediate regime of hyperscaling…
On the IR completion of geometries with hyperscaling violation
Jyotirmoy Bhattacharya, Sera Cremonini, Annamaria Sinkovics
We study solutions to Einstein-Maxwell-dilaton gravity with a constant magnetic flux which describe, in the holographic AdS/CFT framework, field theories characterized by a dynamic…
On the Temperature Dependence of the Shear Viscosity and Holography
Sera Cremonini, Umut Gursoy, Phillip Szepietowski
We examine the structure of the shear viscosity to entropy density ratio eta/s in holographic theories of gravity coupled to a scalar field, in the presence of higher derivative co…
Decoupling Survives Inflation: A Critical Look at Effective Field Theory Violations During Inflation
Anastasios Avgoustidis, Sera Cremonini, Anne-Christine Davis +3
We investigate the validity of effective field theory methods and the decoupling of heavy fields during inflation. Considering models of inflation in which the inflaton is coupled…
