arXivReal Borcherds Superalgebras and Mtheory Pierre HenryLabordere, Bernard Julia, Louis Paulot... more(3) 20021231 The correspondence between del Pezzo surfaces and field theory models over the complex numbers or for split real forms is extended to other real forms, in particular to those compatible with supersymmetry. Specifically, all theories of the Magic triangle that reduce to the pure supergravities in four dimensions correspond to singular real del Pezzo surfaces and the same is true for the Magic square of N=2 SUGRAS. A real del Pezzo surface is the invariant set under an antilinear involution of a complex one. This conjugation induces an involution of the Picard group that preserves the anticanonical class and the intersection form. The known nonsplit Uduality algebras are embedded into superBorcherds algebras defined by their Cartan matrix (minus the intersection form) and fixed by the antiinvolution. These data may be described by TitsSatake bicoloured diagrams. As in the split case, oxidation results from blowing down disjoint real P^1's of selfintersection 1. The singular del Pezzo surfaces of interest are obtained by degenerating regular surfaces upon contraction of real curves of selfintersection 2. We use the finite classification of real simple singularities to exhibit the relevant normal surfaces. We also give a general construction of more magic triangles like a type I split magic triangle and prove their (approximate) symmetry with respect to their diagonal, this symmetry argument was announced in our previous paper for the split case.

arXivOperational indistinguishabilty of doubly special relativities from special relativity D. V. AhluwaliaKhalilova 20021231 We argue that existing doubly special relativities may not be operationally distinguishable from the special relativity. In the process we point out that some of the phenomenologically motivated modifications of dispersion relations, and arrived conclusions, must be reconsidered. Finally, we reflect on the possible conceptual issues that arise in quest for a theory of spacetime with two invariant scales.

arXivAction principle formulation for motion of extended bodies in General Relativity Jeeva Anandan, Naresh Dadhich, Parampreet Singh... more(3) 20021231 We present an action principle formulation for the study of motion of an extended body in General Relativity in the limit of weak gravitational field. This gives the classical equations of motion for multipole moments of arbitrary order coupling to the gravitational field. In particular, a new force due to the octupole moment is obtained. The action also yields the gravitationally induced phase shifts in quantum interference experiments due to the coupling of all multipole moments.

arXivThe Challenging Cosmic Singularity Hong Liu, Gregory Moore, Nathan Seiberg... more(3) 20021231 In this talk we discuss the cosmic singularity. We motivate the need to correct general relativity in the study of singularities, and mention the kind of corrections provided by string theory. We review how string theory resolves timelike singularities with two examples. Then, a simple toy model with lightlike singularities is presented, and studied in classical string theory. It turns out that classical string theory cannot resolve these singularities, and therefore better understanding of the full quantum theory is needed. The implications of this result for the Ekpyrotic/Cyclic Model are discussed. We end by mentioning the known suggestions for explaining the cosmological singularity.

arXivQuantum fluctuations and electronic transport through strongly interacting quantum dots T. A. Costi 20021231 We study electronic transport through a strongly interacting quantum dot by using the finite temperature extension of Wilson's numerical renormalization group (NRG) method. This allows the linear conductance to be calculated at all temperatures and in particular at very low temperature where quantum fluctuations and the Kondo effect strongly modify the transport. The quantum dot investigated has one active level for transport and is modeled by an Anderson impurity model attached to left and right electron reservoirs. The predictions for the linear conductance are compared to available experimental data for quantum dots in heterostructures. The spinresolved conductance is calculated as a function of gate voltage, temperature and magnetic field strength and the spinfiltering properties of quantum dots in a magnetic field are described.
