Einstein-aether Elliptic Charges and the First Law of Asymptotically AdS Black Holes
Walter Arata, Moustafa Ismail, Stefano Liberati +3
We investigate the thermodynamic role of asymptotic aether alignment for universal horizons in Einstein-aether theory. In the static, spherically symmetric, asymptotically AdS sect…

A Covariant Phase Space Approach to Einstein-AEther Gravity
Walter Arata, Stefano Liberati, Giulio Neri
Black hole thermodynamics in Lorentz-violating gravity is subtle because different excitations propagate at different speeds and hence identify different causal horizons. We revisi…
