Implications of Conformal Invariance for Quantum Field Theories in d>2d>2

Recently obtained results for two and three point functions for quasi-primary operators in conformally invariant theories in arbitrary dimensions {\absit d} are described. As a consequence the three point function for the energy momentum tensor has three linearly independent forms for general {\absit d} compatible with conformal invariance. The corresponding coefficients may be regarded as possible generalisations of the Virasoro central charge to {\absit d} larger than 2. Ward identities which link two linear combinations of the coefficients to terms appearing in the energy momentum tensor trace anomaly on curved space are discussed. The requirement of positivity for expectation values of the energy density is also shown to lead to positivity conditions which are simple for a particular choice of the three coefficients. Renormalisation group like equations which express the constraints of broken conformal invariance for quantum field theories away from critical points are postulated and applied to two point functions.\hfill\break Talk presented at the XXVII Ahrenshoop International Symposium.Comment: 14pages, Damtp 93/6

On the Difference Between Being and Object

If philosophy in the wake of Kant’s transcendental revolution tends to orient itself around a subjective principle, namely the human subject, then recently various schools of thought have proposed a counter-revolution in which philosophy is given an objective, non-human starting point. In this historical context, ‘object-oriented ontology’ has sought to gain the status of first philosophy by identifying being in general with the object as such—that is, by systematically converting beings to objects. By tracing the provenance of contemporary object-oriented philosophy to a key moment of late 18th-century German philosophy, this paper develops the idea of the difference between being and object in order to demonstrate that object-oriented thinking, contrary to its anti-Kantian claims, adheres to the central axiom of transcendental idealism, that this axiom is an unsolvable paradox, and that Kant and Novalis give us the resources for a transformative philosophical project that meets the challenge of the cultural and theoretical turn to objects

Eigenvalue correlations in QCD with a chemical potential

We discuss a new Random Matrix Model for QCD with a chemical potential that is based on the symmetries of the Dirac operator and can be solved exactly for all eigenvalue correlations for any number of flavors. In the microscopic limit of small energy levels the results should be an accurate description of QCD. This new model can also be scaled so that all physical observables remain at their $\mu=0$ values until a first order chiral restoration transition is reached. This gives a more realistic model for the QCD phase diagram than previous RMM. We also mention how the model might aid in determining the phase diagram of QCD from future numerical simulations.Comment: 3 pages, 3 figures, Lattice2004(non-zero
