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…
The energy-momentum tensor of perturbed tachyon matter
Niko Jokela, Matti Jarvinen, Esko Keski-Vakkuri
We add an initial nonhomogeneous perturbation to an otherwise homogeneous condensing tachyon background and compute its space time energy-momentum tensor from worldsheet string the…
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…
Holographic Nuclear Physics
Oren Bergman, Gilad Lifschytz, Matthew Lippert
We analyze the phases of the Sakai-Sugimoto model at finite temperature and baryon chemical potential. Baryonic matter is represented either by 4-branes in the 8-branes or by strin…
