Holographic Magnetic Phase Transition
Gilad Lifschytz, Matthew Lippert
We study four-dimensional interacting fermions in a strong magnetic field, using the holographic Sakai-Sugimoto model of intersecting D4 and D8 branes in the deconfined, chiral-sym…
Inhomogeneous tachyon dynamics and the zipper
Niko Jokela, Matthew Lippert
We study the process of inhomogeneous tachyon condensation in an intersecting D1- and anti-D1-brane system using an effective tachyon DBI action. By switching to the Hamiltonian fo…
Anomalous conductivity in holographic QCD
Gilad Lifschytz, Matthew Lippert
We compute the longitudinal and Hall conductivities in the parallel phase of the Sakai-Sugimoto model with a transverse magnetic field. We find that the conductivities behave as if…
Evidence for a bound on the lifetime of de Sitter space
Ben Freivogel, Matthew Lippert
Recent work has suggested a surprising new upper bound on the lifetime of de Sitter vacua in string theory. The bound is parametrically longer than the Hubble time but parametrical…
Probabilities in the landscape: The decay of nearly flat space
Raphael Bousso, Ben Freivogel, Matthew Lippert
We discuss aspects of the problem of assigning probabilities in eternal inflation. In particular, we investigate a recent suggestion that the lowest energy de Sitter vacuum in the…
The information paradox and the locality bound
Steven B. Giddings, Matthew Lippert
Hawking's argument for information loss in black hole evaporation rests on the assumption of independent Hilbert spaces for the interior and exterior of a black hole. We argue that…
