Small gauge transformations and universal geometry in heterotic theories [PDF]

open access: yes, 2020
The first part of this paper describes in detail the action of small gauge transformations in heterotic supergravity. We show a convenient gauge fixing is `holomorphic gauge' together with a condition on the holomorphic top form.

Euclidean-signature Supergravities, Dualities and Instantons [PDF]

open access: yes, 1998
We study the Euclidean-signature supergravities that arise by compactifying D=11 supergravity or type IIB supergravity on a torus that includes the time direction.

Rational deformations of conformal mechanics [PDF]

open access: yes, 2018
We study deformations of the quantum conformal mechanics of De Alfaro-Fubini-Furlan with rational additional potential term generated by applying the generalized Darboux-Crum-Krein-Adler transformations to the quantum harmonic oscillator and by using the

Twistors, Harmonics and Holomorphic Chern-Simons [PDF]

open access: yes, 2013
We show that the off-shell N=3 action of N=4 super Yang-Mills can be written as a holomorphic Chern-Simons action whose Dolbeault operator is constructed from a complex-real (CR) structure of harmonic space.

Spectrum of D=6, N=4b Supergravity on AdS_3 x S^3 [PDF]

open access: yes, 1998
The complete spectrum of D=6, N=4b supergravity with n tensor multiplets compactified on AdS_3 x S^3 is determined. The D=6 theory obtained from the K_3 compactification of Type IIB string requires that n=21, but we let n be arbitrary.

Rotating Intersecting M-Branes [PDF]

open access: yes, 1996
We present intersecting p-brane solutions of eleven-dimensional supergravity (M-branes) which upon toroidal compactification reduce to non-extreme ``rotating'' black holes. We identify harmonic functions, associated with each M-brane, and non-extremality

N=2 supergravity and supercurrents [PDF]

open access: yes, 2010
We address the problem of classifying all N=2 supercurrent multiplets in four space-time dimensions. For this purpose we consider the minimal formulation of N=2 Poincare supergravity with a tensor compensator, and derive its linearized action in terms of

Bogoliubov transformations and exact isolated solutions for simple non-adiabatic Hamiltonians [PDF]

open access: yes, 2001
We present a new method for finding isolated exact solutions of a class of non-adiabatic Hamiltonians of relevance to quantum optics and allied areas. Central to our approach is the use of Bogoliubov transformations of the bosonic fields in the models ...

High-order gauge-invariant perturbations of a spherical spacetime [PDF]

open access: yes, 2007
We complete the formulation of a general framework for the analysis of high-order nonspherical perturbations of a four-dimensional spherical spacetime by including a gauge-invariant description of the perturbations.

Alternative sets of hyperspherical harmonics: Satisfying cusp conditions through frame transformations [PDF]

open access: yes, 1999
By extending the concept of Euler-angle rotations to more than three dimensions, we develop the systematics under rotations in higher-dimensional space for a novel set of hyperspherical harmonics.
