BF Theories and 2-knots
P. Cotta-Ramusino, M. Martellini
We discuss the relations between (topological) quantum field theories in 4 dimensions and the theory of 2-knots (embedded 2-spheres in a 4-manifold). The so-called BF theories allo…
1D-Disordered Conductor with Loops Immersed in a Magnetic Field
A. S. Cattaneo, A. Gamba, I. V. Kolokolov +1
We investigate the conductance of a 1-D disordered conducting loop with two contacts, immersed in a magnetic flux. We show the appearance in this model of the Al'tshuler-Aronov-Spi…
Three-Dimensional Integrable Models and Associated Tangle Invariants
B. L. Cerchiai, M. Martellini, F. Valz-Gris
In this paper we show that the Boltzmann weights of the three-dimensional Baxter-Bazhanov model give representations of the braid group, if some suitable spectral limits are taken.…
A generalized model for two dimensional quantum gravity and dynamics of random surfaces for d>1
M. Martellini, M. Spreafico, K. Yoshida
The possible interpretations of a new continuum model for the two-dimensional quantum gravity for (=matter central charge), obtained by carefully treating both diffeomorph…
