A plethora of K3 metrics
Arnav Tripathy, Max Zimet
We extend our recent study of K3 metrics near the orbifold locus to the other torus orbifold loci. In particular, we provide several new constructions of K3 surfaces as h…
K3 metrics
Shamit Kachru, Arnav Tripathy, Max Zimet
We provide an explicit construction of Ricci-flat K3 metrics. It employs the technology of D-geometry, which in the case of interest is equivalent to a hyper-Kähler quotient. We re…
de Sitter Vacua from Ten Dimensions
Shamit Kachru, Manki Kim, Liam McAllister +1
We analyze the de Sitter construction of \cite{KKLT} using ten-dimensional supergravity, finding exact agreement with the four-dimensional effective theory. Starting from the fermi…
Semiclassical Entropy of BPS States in 4d Theories and Counts of Geodesics
Shamit Kachru, Richard Nally, Arnav Tripathy +1
We relate a number of results in the theory of flat surfaces to BPS spectra of a class of 4d supersymmetric quantum field theories arising from M5 branes wrapped on…
Distributions of extremal black holes in Calabi-Yau compactifications
George Hulsey, Shamit Kachru, Sungyeon Yang +1
We study non-supersymmetric extremal black hole excitations of 4d N=2 supersymmetric string vacua arising from compactification on Calabi-Yau threefolds. The values of the (vector…
K3 metrics from little string theory
Shamit Kachru, Arnav Tripathy, Max Zimet
Certain six-dimensional (1,0) supersymmetric little string theories, when compactified on , have moduli spaces of vacua given by smooth K3 surfaces. Using ideas of Gaiotto-Moo…
