The Yang-Mills vacuum in Coulomb gauge

The Yang-Mills Schr\"odinger equation is solved in Coulomb gauge for the vacuum by the variational principle using an ansatz for the wave functional, which is strongly peaked at the Gribov horizon. We find an infrared suppressed gluon propagator, an infrared singular ghost propagator and an almost linearly rising confinement potential. Using these solutions we calculate the electric field of static color charge distributions relevant for mesons and baryons.Comment: 4 pages, 5 figures, Proceedings ``Confinement Conference Sardinia 2004'

Heat-kernel expansion and counterterms of the Faddeev-Popov determinant in Coulomb and Landau gauge

The Faddeev-Popov determinant of Landau gauge in d dimensions and Coulomb gauge in d+1 dimensions is calculated in the heat-kernel expansion up to next-to-leading order. The UV-divergent parts in d=3,4 are isolated and the counterterms required for a non-perturbative treatment of the Faddeev-Popov determinant are determined.Comment: 7 page

PROSTHETIC SURFACE – DESIGN MODELS FOR A DYNAMIC ARCHITECTURE

The research investigates strategies of dynamic surface formations in a transfer from sartorial fashion to architecture. ‘Remote Control Dress’ (Hussein Chalayan), ‘Dress becomes Body (Rei Kawakubo) and ‘A-Poc’ (Issey Miyake) are precedents of specific technologies and techniques that produce responsive, performative, or phenomenal dresses. These garments can deliver generative surface methods for an architecture operated through the user. The research frames key parameters (cutting scheme, constructive line, programmatic insertions, and operative field) and their respective characteristics and interrelations in analysis. Thus, principles are derived and channeled into performative design models in a media rotation with a conversion between digital and analogue modeling. The paper discusses the potential of these dynamic design models in a design process that addresses the change capacities of architecture in a shifting cultural and programmatic context
