Resistance scaling at the Kosterlitz-Thouless transition

Mats Wallin, Hans Weber

We study the linear resistance at the Kosterlitz-Thouless transition by Monte Carlo simulation of vortex dynamics. Finite size scaling analysis of our data show excellent agreement…

Current--Voltage Characteristics of Two--Dimensional Vortex Glass Models

R. A. Hyman, M. Wallin, M. P. A. Fisher +2

We have performed Monte Carlo simulations to determine current--voltage characteristics of two different vortex glass models in two dimensions. The results confirm the conclusions…

(3+1)-Dimensional Schwinger Terms and Non-commutative Geometry

Edwin Langmann, Jouko Mickelsson

We discuss 2-cocycles of the Lie algebra $\Map(M^3;\g)$ of smooth, compactly supported maps on 3-dimensional manifolds with values in a compact, semi-simple Lie algebra $\g$.…

Periodic orbit asymptotics for intermittent Hamiltonian systems

Per Dahlqvist

We address the problems in applying cycle expansions to bound chaotic systems, caused by e.g. intermittency and incompleteness of the symbolic dynamics. We discuss zeta functions a…

Gauss decomposition of trigonometric R-matrices

Sergei Khoroshkin, A. A. Stolin, V. N. Tolstoy

The general formula for the universal R-matrix for quantized nontwisted affine algebras by Khoroshkin and Tolstoy is applied for zero central charge highest weight modules of the q…

QCD(1+1) with massless quarks and gauge covariant Sugawara construction

E. Langmann, G. W. Semenoff

We use the Hamiltonian framework to study massless QCD, i.e.\ Yang-Mills gauge theories with massless Dirac fermions on a cylinder (= (1+1) dimensional spacetime $S^1\times…

Wodzicki residue and anomalies of current algebras

Jouko Mickelsson

The commutator anomalies (Schwinger terms) of current algebras in dimensions are computed in terms of the Wodzicki residue of pseudodifferential operators; the result can be…

Shell model on a random gaussian basis

K. Varga, R. J. Liotta

Pauli-projected random gaussians are used as a representation to solve the shell model equations. The elements of the representation are chosen by a variational procedure. This sch…

Approximate zeta functions for the Sinai billiard and related systems

Per Dahlqvist

We discuss zeta functions, and traces of the associated weighted evolution operators for intermittent Hamiltonian systems in general and for the Sinai billiard in particular. The i…
