Non-vanishing normal density in cold holographic superfluids
Blaise Goutéraux, Eric Mefford
The low energy and finite temperature excitations of a -dimensional system exhibiting superfluidity are well described by a hydrodynamic model with two fluid flows: a normal f…
Normal charge densities in quantum critical superfluids
Blaise Goutéraux, Eric Mefford
The normal density of a translation-invariant superfluid often vanishes at zero temperature, as is observed in superfluid Helium and conventional superconductors described by BCS t…
Achronal ANEC, Weak Cosmic Censorship, and AdS/CFT duality
Akihiro Ishibashi, Kengo Maeda, Eric Mefford
We examine the achronal averaged null energy condition~(ANEC) for a class of conformal field theories~(CFT) at strong coupling in curved spacetime. By applying the AdS/CFT duality,…
Violation of the quantum null-energy condition in a holographic wormhole and infrared effects
Akihiro Ishibashi, Kengo Maeda, Eric Mefford
We examine the quantum null energy condition (QNEC) for a -dimensional conformal field theory (CFT) at strong coupling in the background of a wormhole spacetime by employing t…
