Review of AdS/CFT Integrability, Chapter II.4: The Spectral Curve

Sakura Schafer-Nameki

We review the spectral curve for the classical string in AdS5xS5. Classical integrability of the AdS5xS5 string implies the existence of a flat connection, whose monodromies genera…

The quantum mechanics of perfect fluids

Solomon Endlich, Alberto Nicolis, Riccardo Rattazzi +1

We consider the canonical quantization of an ordinary fluid. The resulting long-distance effective field theory is derivatively coupled, and therefore strongly coupled in the UV. T…

Aspects of the UV/IR correspondence : energy broadening and string fluctuations

Y. Hatta, E. Iancu, A. H. Mueller +1

We show that a source which radiates in the vacuum of the strongly coupled N=4 SYM theory produces an energy distribution which, in the supergravity approximation, has the same spa…

Galilean currents and charges

Alberto Nicolis

We derive the Noether currents and charges associated with an internal galilean invariance---a symmetry recently postulated in the context of so-called galileon theories. Along the…

An equivalence principle for scalar forces

Lam Hui, Alberto Nicolis

The equivalence of inertial and gravitational masses is a defining feature of general relativity. Here, we clarify the status of the equivalence principle for interactions mediated…

Galilean Genesis: an alternative to inflation

Paolo Creminelli, Alberto Nicolis, Enrico Trincherini

We propose a novel cosmological scenario, in which standard inflation is replaced by an expanding phase with a drastic violation of the Null Energy Condition (NEC): \dot H >> H^2.…

How to Run Through Walls: Dynamics of Bubble and Soliton Collisions

John T. Giblin, Lam Hui, Eugene A. Lim +1

It has recently been shown in high resolution numerical simulations that relativistic collisions of bubbles in the context of a multi-vacua potential may lead to the creation of bu…

Escaping the crunch: gravitational effects in classical transitions

Matthew C Johnson, I-Sheng Yang

During eternal inflation, a landscape of vacua can be populated by the nucleation of bubbles. These bubbles inevitably collide, and collisions sometimes displace the field into a n…

The Heavy Quark Free Energy in QCD and in Gauge Theories with Gravity Duals

Jorge Noronha

We show that the Polyakov loop approaches its asymptotic value at high temperatures {\it from below} in any strongly-coupled gauge theory at large with a dual supergravity de…

Derrick's theorem beyond a potential

Solomon Endlich, Kurt Hinterbichler, Lam Hui +2

Scalar field theories with derivative interactions are known to possess solitonic excitations, but such solitons are generally unsatisfactory because the effective theory fails pre…

Polyakov Loops in Strongly-Coupled Plasmas with Gravity Duals

Jorge Noronha

We study the properties of the Polyakov loop in strongly-coupled gauge plasmas that are conjectured to be dual to five dimensional theories of gravity coupled to a nontrivial singl…

A bulk inflaton from large volume extra dimensions

Brian Greene, Daniel Kabat, Janna Levin +1

The universe may have extra spatial dimensions with large volume that we cannot perceive because the energy required to excite modes in the extra directions is too high. Many examp…
