Mirror Symmetry for Nonabelian Landau-Ginzburg Models
Nathan Priddis, Joseph Ward, Matthew M. Williams
We consider Landau-Ginzburg models stemming from groups comprised of non-diagonal symmetries, and we describe a rule for the mirror LG model. In particular, we present the non-abel…
Point-Particle Effective Field Theory I: Classical Renormalization and the Inverse-Square Potential
C. P. Burgess, Peter Hayman, Matt Williams +1
Singular potentials (the inverse-square potential, for example) arise in many situations and their quantum treatment leads to well-known ambiguities in choosing boundary conditions…
Point-Particle Effective Field Theory II: Relativistic Effects and Coulomb/Inverse-Square Competition
C. P. Burgess, Peter Hayman, Markus Rummel +2
We apply point-particle effective field theory (PPEFT) to compute the leading shifts due to finite-size source effects in the Coulomb bound energy levels of a relativistic spinless…
Remarks on scale separation in flux vacua
F. F. Gautason, M. Schillo, T. Van Riet +1
We argue that the Maldacena-Nunez no-go theorem excluding Minkowski and de Sitter vacua in flux compactifications can be extended to exclude anti-de Sitter (AdS) vacua for which th…
Domain walls inside localised orientifolds
J. Blåbäck, E. van der Woerd, T. Van Riet +1
The equations of motion of toroidal orientifold compactifications with fluxes are in one-to-one correspondence with gauged supergravity if the orientifold (and D-brane) sources are…
A Problem With delta-functions: Stress-Energy Constraints on Bulk-Brane Matching (with comments on arXiv:1508.01124)
C. P. Burgess, Ross Diener, M. Williams
We critically assess a recent assertion (arXiv:1508.01124) concerning using delta-functions to analyze how higher-codimension branes back-react on their environment. We also briefl…
Technically Natural Vacuum Energy at the Tip of a Supersymmetric Teardrop
M. Williams
A minimal supersymmetric brane-world model is presented which has: i) zero classical four-dimensional vacuum curvature, despite the large naive vacuum energy due to contributions f…
