Hyperwave: Hyper-Fast Communication within General Relativity
Lorenzo Pieri
Warp-drives are solutions of general relativity widely considered unphysical due to high negative energy requirements. While the majority of the literature has focused on macroscop…
Black Holes in String Theory
Lorenzo Pieri
Black holes are the hydrogen atoms of quantum gravity. For instance solving the information loss paradox will likely require a deep understanding of how the long-sought quantum gra…
More on microstate geometries of 4d black holes
Massimo Bianchi, Jose Francisco Morales, Lorenzo Pieri +1
We construct explicit examples of microstate geometries of four-dimensional black holes that lift to smooth horizon-free geometries in five dimensions. Solutions consist of half-BP…
Fuzzballs in general relativity: a missed opportunity
Lorenzo Pieri
Recently some 4d asymptotically regular bubbling solutions written in terms of an arbitrary profile function has appeared in literature. We discuss the possibili…
Black hole microstates from branes at angle
Lorenzo Pieri
We derive the leading g_s perturbation of the SUGRA fields generated by a supersymmetric configuration of respectively 1, 2 or 4 D3-branes intersecting at an arbitrary angle via th…
Stringy origin of 4d black hole microstates
Massimo Bianchi, Josè Francisco Morales, Lorenzo Pieri
We derive a precise dictionary between micro-state geometries and open string condensates for a large class of excitations of four dimensional BPS black holes realised in terms of…
