Zwei-Dreibein Gravity
Eric A. Bergshoeff, Sjoerd de Haan, Olaf Hohm +2
We present a generally-covariant and parity-invariant "zwei-dreibein" action for gravity in three space-time dimensions that propagates two massive spin-2 modes, unitarily, and we…
Three-Dimensional Tricritical Gravity
Eric A. Bergshoeff, Sjoerd de Haan, Wout Merbis +2
We consider a class of parity even, six-derivative gravity theories in three dimensions. After linearizing around anti-de Sitter space, the theories have one massless and two massi…
Unitary Truncations and Critical Gravity: a Toy Model
Eric A. Bergshoeff, Sjoerd de Haan, Wout Merbis +2
We investigate a higher-derivative scalar field model in a fixed d+1 dimensional AdS background as a toy model for a gravitational dual to a higher-rank logarithmic CFT. The hologr…
A Non-relativistic Logarithmic Conformal Field Theory from a Holographic Point of View
Eric A. Bergshoeff, Sjoerd de Haan, Wout Merbis +1
We study a fourth-order derivative scalar field configuration in a fixed Lifshitz background. Using an auxiliary field we rewrite the equations of motion as two coupled second orde…
