Para-Statistics as Lie-super Triple Systems
S. Okubo
We first reformulate para-statistics in terms of Lie-super triple systems. In this way, we reproduce various new kinds of para-statistics discovered recently by Palev in addition t…
Alternative Canonical Formalism for the Wess-Zumino-Witten Model
S. G. Rajeev, G. Sparano, P. Vitale
We study a canonical quantization of the Wess--Zumino--Witten (WZW) model which depends on two integer parameters rather than one. The usual theory can be obtained as a contraction…
The Method of Recursive Counting: Can One Go Further?
M. Creutz, I. Horvath, R. Mendris
After a short review of the Method of Recursive Counting we introduce a general algebraic description of recursive lattice building. This provides a rigorous framework for discussi…
Davey-Stewartson Equation from a Zero Curvature and a Self-Duality Condition
J. C. Brunelli, Ashok Das
We derive the two equations of Davey-Stewartson type from a zero curvature condition associated with SL(2,{\bf R}) in dimensions. We show in general how a dimensional z…
Driven Diffusion in the Two-Dimensional Lattice Coulomb Gas; A Model for Flux Flow in Superconducting Networks
Jong-Rim Lee, S. Teitel
We carry out driven diffusion Monte Carlo simulations of the two dimensional classical lattice Coulomb gas in an applied uniform electric field, as a model for vortex motion due to…
Yang-Mills Theory on a Cylinder Coupled to Point Particles
K. S. Gupta, R. J. Henderson, S. G. Rajeev +1
We study a model of quantum Yang-Mills theory with a finite number of gauge invariant degrees of freedom. The gauge field has only a finite number of degrees of freedom since we as…
On the Higher Order Corrections to Heavy Quark Effective Theory
Ashok Das
We show that the different ways of deriving the Heavy Quark Effective Theory (HQET) lead to equivalent theories. The equivalence can be established through a careful redefinition o…
Comment on ``Anomaly-Induced Magnetic Screening in (2+1) Dimensional QED at Finite Density"
C. R. Hagen
It is shown that a recent attempt to derive the Meissner effect from first principles in a model field theory is invalid.
Symplectic Manifolds, Coherent States and Semiclassical Approximation
S. G. Rajeev, S. Kalyana Rama, Siddhartha Sen
We describe the symplectic structure and Hamiltonian dynamics for a class of Grassmannian manifolds. Using the two dimensional sphere () and disc () as illustrative cases…
More on Symmetries in Heavy Quark Effective Theory
Ashok Das, V. S. Mathur
We present a general classification of all normal and ``chiral" symmetries of heavy quark effective theories. Some peculiarities and conondrums associated with the ``chiral" symmet…
Effects of Nongauge Potentials on the Spin-1/2 Aharonov-Bohm Problem
C. R. Hagen
Some recent work has attempted to show that the singular solutions which are known to occur in the Dirac description of spin-1/2 Aharonov-Bohm scattering can be eliminated by the i…
Phase Transitions and Vortex Line Entanglement in a Model High Temperature Superconductor
Ying-Hong Li, S. Teitel
Monte Carlo simulations of the uniformly frustrated 3d XY model are used to model vortex line fluctuations in high temperature superconductors in an applied magnetic field. We find…
Out of Equilibrium Phase Transitions and a Toy Model for Disoriented Chiral Condensates
Paulo Bedaque, Ashok Das
We study the dynamics of a second order phase transition in a situation thatmimics a sudden quench to a temperature below the critical temperature in a model with dynamical symmetr…
Two-Body Nonleptonic Decays of Charmed Mesons
P. Bedaque, A. Das, V. S. Mathur
Two-body nonleptonic decays of charmed mesons are studied on the basis of a simple pole-dominance model involving the vector, pseudoscalar and axial-vector meson poles.
Helicity Modulus and Meissner Effect in a Fluctuating Type II Superconductor
Tao Chen, S. Teitel
The helicity modulus for a fluctuating type II superconductor is computed within the elastic medium approximation, as a probe of superconducting phase coherence and the Meissner ef…
Renormalization in Quantum Mechanics
K. S. Gupta, S. G. Rajeev
We implement the concept of Wilson renormalization in the context of simple quantum mechanical systems. The attractive inverse square potential leads to a $\b$ function with a nont…
Current Algebra and Conformal Field Theory on a Figure Eight
A. P. Balachandran, G. Bimonte, K. S. Gupta +4
We examine the dynamics of a free massless scalar field on a figure eight network. Upon requiring the scalar field to have a well defined value at the junction of the network, it i…
Comment on Operator Algebra in Chern-Simons Theory on a Torus
C. R. Hagen, E. C. G. Sudarshan
It is shown that "nonintegrable phases of Wilson line integrals" are not true dynamical variables in Chern-Simons field theory.
Group actions and deformations for harmonic maps
M. A. Guest, Y. Ohnita
We obtain some new results on classical solutions of two dimensional Euclidean sigma models. From earlier work of Din-Zakrzewski, Glaser-Stora, and numerous differential geometers,…
On the fundamental group of the space of harmonic -spheres in the -sphere
M. Furuta, M. A. Guest, M. Kotani +1
We compute the fundamental group of the "moduli space" of classical solutions of the two dimensional Euclidean -model.
Series expansions without diagrams
Gyan Bhanot, Michael Creutz, Ivan Horvath Jan Lacki +1
We discuss the use of recursive enumeration schemes to obtain low and high temperature series expansions for discrete statistical systems. Using linear combinations of generalized…
Heavy Quark Solitons
Kumar S. Gupta, M. Arshad Momen, J. Schechter +1
We investigate the heavy baryons which arise as solitonic excitations in a ``heavy meson" chiral Lagrangian which includes the light vector particles. It is found that the effect o…
Search for Anomalous Production at TRISTAN
K. L. Sterner
We report on measurements of the total cross section for e+e- --> 2-Gamma for center-of-mass energies between 57.4 and 59.5 GeV, using the AMY detector at the TRISTAN collider. We…
Neutron Acceleration in Uniform Electromagnetic Fields
J. Anandan, C. R. Hagen
The question as to whether neutron acceleration can occur in uniform electromagnetic fields is examined. Although such an effect has been predicted using the canonical equations of…
