Comment on "Attractive Forces between Electrons in 2 + 1 Dimensional QED"

C. R. Hagen

It is shown that a model recently proposed for numerical calculations of bound states in QED is in fact an improper truncation of the Aharonov-Bohm potential.

Triple Products and Yang-Baxter Equation (II): Orthogonal and Symplectic Ternary Systems

S. Okubo

We generalize the result of the preceeding paper and solve the Yang-Baxter equation in terms of triple systems called orthogonal and symplectic ternary systems. In this way, we fou…

Triple Products and Yang-Baxter Equation (I): Octonionic and Quaternionic Triple Systems

S. Okubo

We can recast the Yang-Baxter equation as a triple product equation. Assuming the triple product to satisfy some algebraic relations, we can find new solutions of the Yang-Baxter e…

Magnetic Fields and Passive Scalars in Polyakov's Conformal Turbulence

G. Ferretti, Z. Yang

Polyakov has suggested that two dimensional turbulence might be described by a minimal model of conformal field theory. However, there are many minimal models satisfying the same p…

On the Analytic Structure of the Self-Energy for Massive Gauge Bosons at Finite Temperature

P. Arnold, P. Bedaque, A. Das +1

We show that the one-loop self-energy at finite temperature has a unique limit as the external momentum {\it if} the loop involves propagators with distinct mass…

Self-duality and the Supersymmetric KdV Hierarchy

A. Das, C. A. P. Galvao

We show how the supersymmetric KdV equation can be obtained from the self-duality condition on Yang-Mills fields in four dimension associated with the graded Lie algebra OSp(2/1).…

Two Dimensional Quantum Chromodynamics on a Cylinder

S. Guruswamy, S. G. Rajeev

We study two dimensional Quantum Chromodynamics with massive quarks on a cylinder in a light--cone formalism. We eliminate the non--dynamical degrees of freedom and express the the…

On the Scale-Invariant Distribution of the Diffusion Coefficient for Classical Particles Diffusing in Disordered Media.-

Yan-Chr Tsai, Yonathan Shapir

The scaling form of the whole distribution P(D) of the random diffusion coefficient D(x) in a model of classically diffusing particles is investigated. The renormalization group ap…

Comment on Gauge-Independent Analysis of Chern-Simons Theory with Matter Coupling

C. R. Hagen

It is shown that a recently proposed relativistic field theory of anyons is mathematically flawed and also does not satisfy reasonable criteria for such a theory.

Three Dimensional Quantum Chromodynamics

G. Ferretti, S. G. Rajeev, Z. Yang

The subject of this talk was the review of our study of three () dimensional Quantum Chromodynamics. In our previous works, we showed the existence of a phase where parity is…

Feynman Parametrization and the Degenerate Electron Gas

Paulo F. Bedaque, Ashok Das

We give an alternate derivation of Weldon's formula for combining products of factors with non identical analytic behavior. While such a formula would appear to be useful in finite…

Self-Duality and the KdV Hierarchy

Ashok Das, C. A. P. Galvao

We derive the entire KdV hierarchy as well as the recursion relations from the self-duality condition on gauge fields in four dimensions.

Kinetic Roughening in Surfaces of Crystals Growing on Disordered Substrates

Yan-Chr Tsai, Yonathan Shapir

Substrate disorder effects on the scaling properties of growing crystalline surfaces in solidification or epitaxial deposition processes are investigated. Within the harmonic appro…

Two dimensional baryons in the large N limit

P. F. Bedaque, I. Horvath, S. G. Rajeev

We propose a bilocal field theory for mesons in two dimensions obtained as a kind of non local bosonization of two dimensional QCD. Its semi-classical expansion is equivalent to th…

Current Algebra in Three Dimensions

G. Ferretti, S. G. Rajeev

We study a three dimensional analogue of the Wess--Zumino--Witten model, which describes the Goldstone bosons of three dimensional Quantum Chromodynamics. The topologically non--tr…

A Note on ``Anomalous" Chiral Gauge Theories

Zhu Yang

We show that, the lattice regularization of chiral gauge theories proposed by Kaplan, when applied to a (2+1)-dimensional domain wall, produces a (1+1)-dimensional theory at low en…

Self-Duality in 3+3 Dimensions and the KP Equation

A. Das, E. Sezgin, Z. Khviengia

We consider two types of generalized self-duality conditions for Yang-Mills fields on paracomplex manifolds of arbitrary dimension. We then specialize to dimensions and show…

High Temperature Partition Function of the Rigid String

Joseph Polchinski, Zhu Yang

We find that the high temperature limit of the free energy per unit length for the rigid string agrees dimensionally with that of the QCD string (unlike the Nambu-Goto string). The…

Baryons as Solitons in Three Dimensional Quantum Chromodynamics

G. Ferretti, S. G. Rajeev, Z. Yang

We show that baryons of three dimensional Quantum Chromodynamics can be understood as solitons of its effective lagrangian. In the parity preserving phase we study, these baryons a…

The Effective Lagrangian of Three Dimensional Quantum Chromodynamics

G. Ferretti, S. G. Rajeev, Z. Yang

We consider the low energy limit of three dimensional Quantum Chromodynamics with an even number of flavors. We show that Parity is not spontaneously broken, but the global (flavor…

Model With a Chern-Simons Term

G. Ferretti, S. G. Rajeev

The model in three euclidean dimensions is studied in the presence of a Chern-Simons term using the expansion. The -function for the CS coefficient is found to…
