A bstractTheories of massive gravity inevitably include an auxiliary reference metric. Generically, they also contain an… Expand A bstractWe construct consistent theories of multiple interacting spin-2 fields in arbitrary spacetime dimensions using a… Expand We address the uniqueness of the minimal couplings between higher-spin fields and gravity. These couplings are cubic vertices… Expand We give an independent derivation of the Engle-Pereira-Rovelli spinfoam model for quantum gravity which recently appeared in… Expand Recently, Arkani-Hamed, Dimopoulos, and Dvali have proposed that there are extra compact dimensions of space, accessible to… Expand We propose an error correction coding algorithm for continuous quantum variables. We use this algorithm to construct a highly… Expand Field theory calculations predict multiplicative logarithmic corrections to correlation functions from marginally irrelevant… Expand We have found that the usual measuring procedure for preselected and postselected ensembles of quantum systems gives unusual… Expand Photons can mix with low-mass bosons in the presence of external electromagnetic fields if these particles---not necessarily of… Expand L'etat fondamental d'antiferromagnetiques d'Heisenberg a spin 1/2 a reseaux carre et triangulaire est determine par une extension… Expand
