Evaluation of Observables in the Gaussian Kazakov-Migdal Model
M. Dobroliubov, A. Morozov, G. Semenoff +1
We examine the properties of observables in the Kazakov-Migdal model. We present explicit formulae for the leading asymptotics of adjoint Wilson loops as well as some other observa…
Phase Space Isometries and Equivariant Localization of Path Integrals in Two Dimensions
Richard J. Szabo, Gordon W. Semenoff
By considering the most general metric which can occur on a contractable two dimensional symplectic manifold, we find the most general Hamiltonians on a two dimensional phase space…
A Kuchař Hypertime Formalism For Cylindrically Symmetric Spacetimes With Interacting Scalar Fields
Stephen P. Braham
The Kuchař canonical transformation for vacuum geometrodynamics in the presence of cylindrical symmetry is applied to a general non-vacuum case. The resulting constraints are highl…
Tunneling in Quantum Wires: a Boundary Conformal Field Theory Approach
Eugene Wong, Ian Affleck
Tunneling through a localized barrier in a one-dimensional interacting electron gas has been studied recently using Luttinger liquid techniques. Stable phases with zero or unit tra…
S(k) for Haldane Gap Antiferromagnets: Large-scale Numerical Results vs. Field Theory and Experiment
E. Sorensen, I. Affleck
The structure function, S(k), for the s=1, Haldane gap antiferromagnetic chain, is measured accurately using the recent density matrix renormalization group method, with chain-leng…
A Simple Formula for the Persistent Current in Disordered 1D Rings: Parity and Interaction Effects
Alexander O. Gogolin, Nikolai V. Prokof'ev
The general expression for the persistent current of 1D noninteracting electrons in a disorder potential with smooth scattering data is derived for zero temperature. On the basis o…
Monopole-Catalysed Baryon Decay: A Boundary Conformal Field Theory Approach
Ian Affleck, Jacob Sagi
Monopole-mediated baryon number violation, the Callan-Rubakov effect, is reexamined using boundary conformal field theory techniques. It is shown that the low-energy behaviour is d…
On the Observability of Meso- and Macro-scopic Quantum Coherence of Domain Walls in Magnetic Insulators
Frank Gaitan
Results are presented of a numerical calculation of the tunneling gap for a domain wall moving in the double well potential of a pair of voids in a magnetic insulator. Both symmetr…
Coupling and Harnack inequalities for Sierpinski carpets
Martin T. Barlow, Richard F. Bass
Uniform Harnack inequalities for harmonic functions on the pre- and graphical Sierpinski carpets are proved using a probabilistic coupling argument. Various results follow from thi…
Kondo Crossover In The Self-Consistent One-Loop Approximation"
Junwu Gan
The free energy and magnetization for the general one impurity Kondo model in the magnetic field, , are calculated by extending the previous expansion technique: t…
On The Multichannel Kondo Model"
Junwu Gan
A detailed and comprehensive study of the one-impurity multichannel Kondo model is presented. In the limit of a large number of conduction electron channels , the low ener…
Non-Fermi Liquid Behavior In Quantum Critical Systems
Junwu Gan, Eugene Wong
The problem of an electron gas interacting via exchanging transverse gauge bosons is studied using the renormalization group method. The long wavelength behavior of the gauge field…
The superconductor-insulator transition in 2D dirty boson systems
M. Wallin, E. Sorensen, S. M. Girvin +1
Universal properties of the zero temperature superconductor-insulator transition in two-dimensional amorphous films are studied by extensive Monte Carlo simulations of bosons in a…
Equivalence of Several Chern-Simons Matter Models
Wei Chen, Chigak Itoi
Not only does Chern-Simons (CS) coupling characterize statistics, but also spin and scaling dimension of matter fields. We demonstrate spin transmutation in relativistic CS matter…
Star counts in NGC 6397
G. A. Drukier, G. G. Fahlman, H. B. Richer +2
I-band CCD images of a large area of the nearby globular cluster NGC~6397 have been used to construct a surface density profile and two luminosity and mass functions. The surface d…
Consistent axial--like gauge fixing on hypertori
Edwin Langmann, Manfred Salmhofer, Alex Kovner
We analyze the Gribov problem for $\SU(N)$ and $\U(N)$ Yang-Mills fields on -dimensional tori, . We give an improved version of the axial gauge condition and find…
The Reality and Measurement of the Wavefunction
W. G. Unruh
Using a simple version of the model for the quantum measurement of a two level system, the contention of Aharonov, Anandan, and Vaidman that one must in certain circumstances give…
Solution to 2+1 Gravity in DreiBein formalism
W. G. Unruh, Peter Newbury
The reduction of the dreibein formalism of 2+1 General Relativity to the holonomies is explicitly performed. We also show explicitly how to relate these holonomies to a geometry cl…
Generalized Sums over Histories for Quantum Gravity II. Simplicial Conifolds
Kristin Schleich, Donald M. Witt
This paper examines the issues involved with concretely implementing a sum over conifolds in the formulation of Euclidean sums over histories for gravity. The first step in precise…
Generalized Sums over Histories for Quantum Gravity I. Smooth Conifolds
Kristin Schleich, Donald M. Witt
This paper proposes to generalize the histories included in Euclidean functional integrals from manifolds to a more general set of compact topological spaces. This new set of space…
Scattering From a Two Dimensional Array of Flux Tubes: A Study of The Validity of Mean Field Theory
Ken Kiers, Nathan Weiss
Mean Field Theory has been extensively used in the study of systems of anyons in two spatial dimensions. In this paper we study the physical grounds for the validity of this approx…
Fermi-Edge Singularity with Backscattering in the Luttinger-Liquid Model
N. V. Prokof'ev
We study the response of the interacting electron gas in one dimension on the local external potential. In the low frequency limit the power-law singularities are essentially modif…
