Lattice Topological Field Theory in Two Dimensions
M. Fukuma, S. Hosono, H. Kawai
The lattice definition of a two-dimensional topological field theory (TFT) is given generically, and the exact solution is obtained explicitly. In particular, the set of all lattic…
Do Solar Neutrino Experiments Imply New Physics?
John N. Bahcall, H. A. Bethe
None of the 1000 solar models in a full Monte Carlo simulation is consistent with the results of the chlorine or the Kamiokande experiments. Even if the solar models are forced art…
Eluding the no-hair conjecture: Black holes in spontaneously broken gauge theories
Brian R. Greene, Samir D. Mathur, Christopher M. O'Neill
We study regular and black hole solutions to the coupled classical Einstein--Yang-Mills--Higgs system. It has long been thought that black hole solutions in the spontaneously broke…
Spin tunneling in the Kagomé antiferromagnet
Jan von Delft, Christopher L. Henley
The collective tunneling of a small cluster of spins between two degenerate ground state configurations of the Kagomé-lattice quantum Heisenberg antiferromagnet is \mbox{studied}.…
Hysteresis and hierarchies: dynamics of disorder-driven first-order phase transformations
James P. Sethna, Karin Dahmen, Sivan Kartha +3
We use the zero-temperature random-field Ising model to study hysteretic behavior at first-order phase transitions. Sweeping the external field through zero, the model exhibits hys…
Many Body Theory of Charge Transfer in Hyperthermal Atomic Scattering
J. B. Marston, D. R. Andersson, E. R. Behringer +4
We use the Newns-Anderson Hamiltonian to describe many-body electronic processes that occur when hyperthermal alkali atoms scatter off metallic surfaces. Following Brako and Newns,…
Multiphoton Production at High Energies in the Standard Model II
G. Mahlon
We examine multiphoton production in the electroweak sector of the Standard Model in the high energy limit using the equivalence theorem in combination with spinor helicity techniq…
Multiphoton Production at High Energies in the Standard Model I
G. Mahlon, T. M. Yan
We examine multiphoton production in the electroweak sector of the Standard Model in the high energy limit using the equivalence theorem in combination with spinor helicity techniq…
Generalized Gluon Currents and Applications in QCD
G. Mahlon, T. M. Yan, C. Dunn
We consider the process containing two quark lines and an arbitrary number of gluons in a spinor helicity framework. A current with two off-shell gluons appears in the amplitude. W…
Quantum Affine Symmetry as Generalized Supersymmetry
A. LeClair, C. Vafa
The quantum affine $\CU_q (\hat{sl(2)}) $ symmetry is studied when is an even root of unity. The structure of this algebra allows a natural generalization of N=2 supersymmetr…
On the Viability of Lattice Perturbation Theory
G. P. Lepage, P. B. Mackenzie
In this paper we show that the apparent failure of QCD lattice perturbation theory to account for Monte Carlo measurements of perturbative quantities results from choosing the bare…
Chiral Lagrangians for Radiative Decays of Heavy Hadrons
H. Y. Cheng, C. Y. Cheung, G. L. Lin +3
The radiative decays of heavy mesons and heavy baryons are studied in a formalism which incorporates both the heavy quark symmetry and the chiral symmetry. The chiral Lagrangians f…
Electromagnetic response of a static vortex line in a type-II superconductor : a microscopic study
Boldizsar Janko, Joel D. Shore
The electromagnetic response of a pinned Abrikosov fluxoid is examined in the framework of the Bogoliubov-de Gennes formalism. The matrix elements and the selection rules for both…
Destructive quantum interference in spin tunneling problems
Jan von Delft, Christopher L. Henley
In some spin tunneling problems, there are several different but symmetry-related tunneling paths that connect the same initial and final configurations. The topological phase fact…
Melting a copper cluster: Critical droplet theory
Ole H. Nielsen, James P. Sethna, Per Stoltze +2
We simulate the melting of a 71 A diameter cluster of Cu. At low temperatures the crystal exhibits facets. With increasing temperatures the open facets pre-melt, the melted regions…
Sine-Gordon =/= Massive Thirring, and Related Heresies
Timothy R. Klassen, Ezer Melzer
By viewing the Sine-Gordon and massive Thirring models as perturbed conformal field theories one sees that they are different (the difference being observable, for instance, in fin…
S-matrices for Perturbed N=2 Superconformal Field Theory from quantum groups
A. LeClair, D. Nemeschansky, N. P. Warner
S-matrices for integrable perturbations of superconformal field theories are studied. The models we consider correspond to perturbations of the coset theory $G_k \times H_{g-…
Low-Lying States of the Six-Dimensional Fractional Superstring
P. C. Argyres, E. Lyman, S. -H. H. Tye
The fractional superstring Fock space is constructed in terms of $\bZ_4$ parafermions and free bosons. The bosonization of the $\bZ_4$ parafermion theory and the generalized…
Polynomial diffeomorphisms of C^2, IV: The measure of maximal entropy and laminar currents
Eric Bedford, Mikhail Lyubich, John Smillie
This paper concerns the dynamics of polynomial automorphisms of . One can associate to such an automorphism two currents and the equilibrium measure $μ=μ^+\wedge…
The Quantum Double in Integrable Quantum Field Theory
D. Bernard, A. LeClair
Various aspects of recent works on affine quantum group symmetry of integrable 2d quantum field theory are reviewed and further clarified. A geometrical meaning is given to the qua…
Improved Nonrelativistic QCD for Heavy Quark Physics
G. P. Lepage, L. Magnea, C. Nakhleh +2
We construct an improved version of nonrelativistic QCD for use in lattice simulations of heavy quark physics, with the goal of reducing systematic errors from all sources to below…

Geoffrey T. Bodwin, Eric Braaten, G. Peter Lepage
Rigorous QCD predictions for decay rates of the P-wave states of heavy quarkonia are presented. They are based on a new factorization theorem which is valid to leading order in the…
Bilinear Quantum Monte Carlo: Expectations and Energy Differences
Shiwei Zhang, M. H. Kalos
We propose a bilinear sampling algorithm in Green's function Monte Carlo for expectation values of operators that do not commute with the Hamiltonian and for differences between ei…
Logarithmically slow domain growth in nonrandomly frustrated systems: Ising models with competing interactions
Joel D. Shore, Mark Holzer, James P. Sethna
It is known that in systems which contain randomness explicitly in their Hamiltonians (e.g., due to impurities), the characteristic size L of the ordered domains can grow only loga…
