On the geometry and quantum theory of regular and singular spinors
G. Papadopoulos
We relate the Lounesto classification of regular and singular spinors to the orbits of the group in the space of Dirac spinors. We find that regular spinors are associa…
Rotating Rotated Branes
G. Papadopoulos
We present a class of spacetime rotations that preserve a proportion of spacetime supersymmetry. We then give the rules for superposing these rotations with various branes to const…
Multi-angle Five-Brane Intersections
G. Papadopoulos, A. Teschendorff
We find new solutions of IIA supergravity which have the interpretation of intersecting NS-5-branes at -angles on a string preserving at least 3/32 of supersymmetry. We show…
The Moduli Spaces of Worldvolume Brane Solitons
J. Gutowski, G. Papadopoulos
We compute the moduli metrics of worldvolume 0-brane solitons of D-branes and the worldvolume self-dual string solitons of the M-5-brane and examine their geometry. We find that th…
Instantons at Angles
G. Papadopoulos, A. Teschendorff
We interpret a class of 4k-dimensional instanton solutions found by Ward, Corrigan, Goddard and Kent as four-dimensional instantons at angles. The superposition of each pair of fou…
Kaluza-Klein on the Brane
G. Papadopoulos, P. K. Townsend
The M-theory interpretation of certain D=10 IIA p-branes implies the existence of worldvolume Kaluza-Klein modes which are expected to appear as 0-brane/p-brane bound states preser…
