Generating Rotation in a Snap
Soumangsu Chakraborty, Pierre Heidmann, Gela Patashuri
We build a technique to generate rotation from arbitrary static solutions that asymptote to four- or five-dimensional Minkowski spacetime based on Clément's approach [1]. The meth…
Microstates of Non-extremal Black Holes: A New Hope
Soumangsu Chakraborty, Pierre Heidmann
We provide a new roadmap for constructing microstates of non-extremal black holes in supergravity. First, we review the non-linear sigma model of five-dimensional supergravity gove…
Effective
Soumangsu Chakraborty, Amit Giveon, David Kutasov
In arXiv:2109.00065, it was pointed out that superstring theory on with -field background and is dual to a symmetric product CFT deform…
Path integral of free fields and the determinant of Laplacian in warped space-time
Soumangsu Chakraborty, Akikazu Hashimoto, Horatiu Nastase
We revisit the problem of computing the determinant of Klein-Gordon operator on Euclideanized with the Euclideanized time coordinate compactified with…
The M2-M5 Mohawk
Iosif Bena, Soumangsu Chakraborty, Dimitrios Toulikas +1
We show that the near-brane back-reaction of M2 branes ending on M5 branes has a rich "spike structure" that is determined by partitioning the numbers of M2 branes that are termina…
