Viscosity Bound and Causality in Superfluid Plasma
Alex Buchel, Sera Cremonini
It was argued by Brigante et.al that the lower bound on the ratio of the shear viscosity to the entropy density in strongly coupled plasma is translated into microcausality violati…
Correlation Functions and Hidden Conformal Symmetry of Kerr Black Holes
Melanie Becker, Sera Cremonini, Waldemar Schulgin
Extremal scalar three-point correlators in the near-NHEK geometry of Kerr black holes have recently been shown to agree with the result expected from a holographically dual non-chi…
On Non-Canonical Kinetic Terms and the Tilt of the Power Spectrum
Sera Cremonini, Zygmunt Lalak, Krzysztof Turzynski
We argue that in models of inflation with two scalar fields and non-canonical kinetic terms there is a possibility of obtaining a red tilt of the power spectrum of curvature pertur…
Extremal Three-point Correlators in Kerr/CFT
Melanie Becker, Sera Cremonini, Waldemar Schulgin
We compute three-point correlation functions in the near-extremal, near-horizon region of a Kerr black hole, and compare to the corresponding finite-temperature conformal field the…
