On BPS Branes
Cumrun Vafa, David H. Wu, Kai Xu
We study supersymmetric BPS branes (BPS-B) in supergravity theories. Some of these states are anticipated by BPS black-brane (BPS-BB) solutions of supergravity. In particular, we d…
Holes in Calabi-Yau Effective Cones
Naomi Gendler, Elijah Sheridan, Michael Stillman +1
Motivated by their role in non-perturbative potentials in string theory, we study divisors in effective cones of Calabi-Yau threefolds. We give examples of geometries for which som…
E-Strings and Four-Manifolds
Du Pei, David H. Wu
We investigate the physics of the E-string theory and its compactifications as well as their applications to four-dimensional topology. In particular, we compute the partition func…
String stars in
Alek Bedroya, David Wu
We raise a thermodynamic puzzle for Horowitz--Polchinski (HP) solutions in the presence of extra compact dimensions and show that it can be resolved by the existence of higher-dime…
The Tale of Three Scales: the Planck, the Species, and the Black Hole Scales
Alek Bedroya, Cumrun Vafa, David H. Wu
Quantum gravity (QG) has a natural cutoff given by the Planck scale . However, it is known that the EFT of gravity can break down at a lower scale, the species scale $Λ…
Species Scale in Diverse Dimensions
Damian van de Heisteeg, Cumrun Vafa, Max Wiesner +1
In a quantum theory of gravity, the species scale can be defined as the scale at which corrections to the Einstein action become important or alternatively as codifying the "…
Bounds on Field Range for Slowly Varying Positive Potentials
Damian van de Heisteeg, Cumrun Vafa, Max Wiesner +1
In the context of quantum gravitational systems, we place bounds on regions in field space with slowly varying positive potentials. Using the fact that , where is…
Moduli-dependent Species Scale
Damian van de Heisteeg, Cumrun Vafa, Max Wiesner +1
The counting of the number of light modes in a gravitational theory is captured by the notion of the `species scale', which serves as an effective UV cutoff below the Planck scale.…
Resurgent Analysis of SU(2) Chern-Simons Partition Function on Brieskorn Spheres
David H. Wu
-invariants, which can reconstruct the analytic continuation of the SU(2) Chern-Simons partition functions via Borel resummation, were discovered by GPV and have been conj…
