Holography in Rindler Space
 
 

Rindler space has been studied in great detail within the context of quantum field theory. However, a quantum gravitational treatment of Rindler space is handicapped by the fact that quantum gravity in flat space is poorly understood. By contrast, quantum gravity in anti-de Sitter space (AdS), is relatively well understood via the AdS/CFT correspondence. Taking this cue, we construct Rindler coordinates for AdS (RAdS) space in d + 1 spacetime dimensions. Specializing to three spacetime dimensions, we find novel one-parameter families of stationary vacua which possess an observer-dependent ergoregion in addition to having an event horizon. By applying the AdS/CFT correspondence to Rindler-AdS space, we derive the thermodynamics of Rindler-AdS space, and also probe the causal structure of the spacetime by sending in a time-like source into the Rindler horizon.
