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…
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…
Black holes and Bhargava's invariant theory
Murat Gunaydin, Shamit Kachru, Arnav Tripathy
Attractor black holes in type II string compactifications on are in correspondence with equivalence classes of binary quadratic forms. The discriminant of the quadr…
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…
Recounting Special Lagrangian Cycles in Twistor Families of K3 Surfaces. Or: How I Learned to Stop Worrying and Count BPS States
Shamit Kachru, Arnav Tripathy, Max Zimet
We consider asymptotics of certain BPS state counts in M-theory compactified on a K3 surface. Our investigation is parallel to (and was inspired by) recent work in the mathematics…
