Spontaneous Symmetry Probing

Alberto Nicolis, Federico Piazza

For relativistic quantum field theories, we consider Lorentz breaking, spatially homogeneous field configurations or states that evolve in time along a symmetry direction. We dub t…

Superembedding methods for 4d N=1 SCFTs

Walter D. Goldberger, Witold Skiba, Minho Son

We extend SO(4,2) covariant lightcone embedding methods of four-dimensional CFTs to N=1 superconformal field theory (SCFT). Manifest superconformal SU(2,2|1) invariance is achieved…

On Black Holes in Massive Gravity

L. Berezhiani, G. Chkareuli, C. de Rham +2

In massive gravity the so-far-found black hole solutions on Minkowski space happen to convert horizons into a certain type of singularities. Here we explore whether these singulari…

Confirmation of the Secondary Constraint and Absence of Ghost in Massive Gravity and Bimetric Gravity

S. F. Hassan, Rachel A. Rosen

In massive gravity and in bimetric theories of gravity, two constraints are needed to eliminate the two phase-space degrees of freedom of the Boulware-Deser ghost. For recently pro…

Dissipative effects in the Effective Field Theory of Inflation

Diana Lopez Nacir, Rafael A. Porto, Leonardo Senatore +1

We generalize the effective field theory of single clock inflation to include dissipative effects. Working in unitary gauge we couple a set of composite operators in the effective…

Bimetric Gravity from Ghost-free Massive Gravity

S. F. Hassan, Rachel A. Rosen

Generically, non-linear bimetric theories of gravity suffer from the same Boulware-Deser ghost instability as non-linear theories of massive gravity. However, recently proposed the…

Ghost-free Massive Gravity with a General Reference Metric

S. F. Hassan, Rachel A. Rosen, Angnis Schmidt-May

Theories of massive gravity inevitably include an auxiliary reference metric. Generically, they also contain an inconsistency known as the Boulware-Deser ghost. Recently, a family…

A holographic model for large N thermal QCD

Mohammed Mia, Keshav Dasgupta, Charles Gale +1

We summarize the dual gravity description for a thermal gauge theory, reviewing the key features of our holographic model of large N QCD and elaborating on some new results.The the…

Classical Stability of the Galileon

Solomon Endlich, Junpu Wang

We consider the classical equations of motion for a single Galileon field with generic parameters in the presence of non-relativistic sources. We introduce the concept of absolute…

Strongly Warped BPS Domain Walls

Ali Masoumi, I-Sheng Yang

We present analytical solutions of BPS domain walls in the Einstein-Maxwell flux landscape. We also remove the smeared-branes approximation and write down solutions with localized…

Effective field theory for hydrodynamics: thermodynamics, and the derivative expansion

Sergei Dubovsky, Lam Hui, Alberto Nicolis +1

We consider the low-energy effective field theory describing the infrared dynamics of non-dissipative fluids. We extend previous work to accommodate conserved charges, and we clari…

Brane-World Motion in Compact Dimensions

Brian Greene, Janna Levin, Maulik Parikh

The topology of extra dimensions can break global Lorentz invariance,singling out a globally preferred frame even in flat spacetime. Through experiments that probe global topology,…

Radiation by a heavy quark in N=4 SYM at strong coupling

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

Using the AdS/CFT correspondence in the supergravity approximation, we compute the energy density radiated by a heavy quark undergoing some arbitrary motion in the vacuum of the st…

Can we live in the bulk without a brane?

Kurt Hinterbichler, Janna Levin, Claire Zukowski

We suggest a braneless scenario that still hides large-volume extra dimensions. Ordinarily the strength of bulk gauge interactions would be diluted over the large internal volume,…
