A Lattice Universe from M-theory
M. J. Duff, P. Hoxha, H. Lu +2
A recent paper on the large-scale structure of the Universe presented evidence for a rectangular three-dimensional lattice of galaxy superclusters and voids, with lattice spacing ~…
Gauge Dyonic Strings and Their Global Limit
M. J. Duff, J. Liu, H. Lu +1
We show that six-dimensional supergravity coupled to tensor and Yang-Mills multiplets admits not one but two different theories as global limits, one of which was previously though…
Fibre Bundles and Generalised Dimensional Reduction
I. V. Lavrinenko, H. Lu, C. N. Pope
We study some geometrical and topological aspects of the generalised dimensional reduction of supergravities in D=11 and D=10 dimensions, which give rise to massive theories in low…
Interacting Intersections
H. Lu, C. N. Pope
Intersecting p-branes can be viewed as higher-dimensional interpretations of multi-charge extremal p-branes, where some of the individual p-branes undergo diagonal dimensional oxid…
Dualisation of Dualities, I
E. Cremmer, B. Julia, H. Lu +1
We analyse the global (rigid) symmetries that are realised on the bosonic fields of the various supergravity actions obtained from eleven-dimensional supergravity by toroidal compa…
Multiplet Structures of BPS Solitons
H. Lu, C. N. Pope, K. S. Stelle
There exist simple single-charge and multi-charge BPS p-brane solutions in the D-dimensional maximal supergravities. From these, one can fill out orbits in the charge vector space…
Spectrum-generating Symmetries for BPS Solitons
E. Cremmer, H. Lu, C. N. Pope +1
We show that there exist nonlinearly realised duality symmetries that are independent of the standard supergravity global symmetries, and which provide active spectrum-generating s…
Classification of p-branes, NUTs, Waves and Intersections
H. Lu, C. N. Pope, T. R. Tran +1
We give a full classification of the multi-charge supersymmetric -brane solutions in the massless and massive maximal supergravities in dimensions obtained from the toro…
Cosmological solutions, p-branes and the Wheeler-DeWitt equation
H. Lu, J. Maharana, S. Mukherji +1
The low energy effective actions which arise from string theory or M-theory are considered in the cosmological context, where the graviton, dilaton and antisymmetric tensor field s…
Supersymmetry without Supersymmetry
M. J. Duff, H. Lu, C. N. Pope
We present four-dimensional M-theory vacua with N>0 supersymmetry which, from the perspective of perturbative Type IIA string theory, have N=0. Such vacua can appear when the compa…
Towards a Field Theory of F-theory
N. Khviengia, Z. Khviengia, H. Lu +1
We make a proposal for a bosonic field theory in twelve dimensions that admits the bosonic sector of eleven-dimensional supergravity as a consistent truncation. It can also be cons…
T-duality and U-duality in toroidally-compactified strings
H. Lu, C. N. Pope
We address the issue of T-duality and U-duality symmetries in the toroidally-compactified type IIA string. It is customary to take as a starting point the dimensionally-reduced max…
p-brane Taxonomy
H. Lu, C. N. Pope
We review an approach to the construction and classification of p-brane solitons in arbitrary dimensions, with an emphasis on those that arise in toroidally-compactified M-theory.…
Harmonic superpositions of non-extremal p-branes
I. V. Lavrinenko, H. Lu, C. N. Pope +1
The plot of allowed p and D values for p-brane solitons in D-dimensional supergravity is the same whether the solitons are extremal or non-extremal. One of the useful tools for rel…
