Reflection symmetry at a B=0 metal-insulator transition in two dimensions
D. Simonian, S. V. Kravchenko, M. P. Sarachik
We report a remarkable symmetry between the resistivity and conductivity on opposite sides of the B=0 metal-insulator transition in a two-dimensional electron gas in high-mobility…
A Strong-Coupling Analysis of the Lattice Models in the Presence of a Term
Jan Plefka, Stuart Samuel
A term, which couples to topological charge, is added to the lattice model. The strong-coupling character expansion is developed. The series for the free energy and…
Quantum Versus Mean Field Behavior of Normal Modes of a Bose-Einstein Condensate in a Magnetic Trap
A. B. Kuklov, N. Chencinski, A. M. Levine +2
Quantum evolution of a collective mode of a Bose-Einstein condensate containing a finite number N of particles shows the phenomena of collapses and revivals. The characteristic col…
Nonequilibrium transport and population inversion in double quantum dot systems
Jun Zang, Joseph L Birman, A. R. Bishop +1
We present a microscopic theory for both equilibrium and nonequilibrium transport properties of coupled double quantum dots (DQD). A general formula for current tunneling through t…
Small cancellation groups and translation numbers
Ilya Kapovich
In this paper we prove that C(4)-T(4)-P, C(3)-T(6)-P and C(6)-P small cancellation groups are translation dis crete in the strongest possible sense and that in these groups for any…
Nonequilibrium Neutrino Oscillations in the Early Universe with an Inverted Neutrino-Mass Hierarchy
V. Alan Kostelecky, Stuart Samuel
The annihilation of electron-positron pairs around one second after the big bang distorts the Fermi-Dirac spectrum of neutrino energies. We determine the distortions assuming neutr…
Gauge invariance and mass gap in (2+1)-dimensional Yang-Mills theory
Dimitra Karabali, V. P. Nair
In terms of a gauge-invariant matrix parametrization of the fields, we give an analysis of how the mass gap could arise in non-Abelian gauge theories in two spatial dimensions.
On Non-Abelian Thomas-Fermi Screening
G. Alexanian, V. P. Nair
The Thomas-Fermi screening of non-Abelian gauge fields by fermions or screening of gluon fields in quark matter is discussed. It is described by an effective mass term which is, as…
Non Abelian Bosonization in Two and Three Dimensions
J. C. Le Guillou, E. Moreno, C. Nunez +1
We discuss non-Abelian bosonization of two and three dimensional fermions using a path-integral framework in which the bosonic action follows from the evaluation of the fermion det…
Recursion Rules for Scattering Amplitudes in Non-Abelian Gauge Theories
Chanju Kim, V. P. Nair
We present a functional derivation of recursion rules for scattering amplitudes in a non-Abelian gauge theory in a form valid to arbitrary loop order. The tree-level and one-loop r…
Electric field scaling at a B=0 metal-insulator transition in two dimensions
S. V. Kravchenko, D. Simonian, M. P. Sarachik +2
The non-linear (electric field-dependent) resistivity of the 2D electron system in silicon exhibits scaling as a function of electric field and electron density in both the metalli…
A Note on the Stability of Quantum Supermembranes
Michio Kaku
We re-examine the question of the stability of quantum supermembranes. In the past, the instability of supermembranes was established by using a regulator, i.e. approximating the m…
Collective Variables of Fermions and Bosonization
B. Sakita
We first present a general method for extracting collective variables out of non-relativistic fermions by extending the gauge theory of collective coordinates to fermionic systems.…
How Unstable Are Fundamental Quantum Supermembranes?
Michio Kaku
String duality requires the presence of solitonic -branes. By contrast, the existence of fundamental supermembranes is problematic, since they are probably unstable. In this pap…
Time Dependent Behavior of Granular Material in a Vibrating Box
Jysoo Lee
Using numerical and analytic methods, we study the time dependent behavior of granular material in a vibrating box. We find, by molecular dynamics simulation, that the temporal flu…
Generalized primitive elements of a free group
Vladimir Shpilrain
We study endomorphisms of a free group of finite rank by means of their action on specific sets of elements. In particular, we prove that every endomorphism of the free group of ra…
Hyperbolic groups and free constructions
Olga Kharlampovich, Alexey Myasnikov
We investigate which free constructions (amalgamated products and HNN-extensions) over word hyperbolic groups produce groups that are again word hyperbolic. A complete answer is ob…
On the Glueball Mass
Stuart Samuel
An approximate vacuum wave functional is proposed for -dimensional Yang-Mills theories. Using , one can compute the glueball mass in terms of the str…
Finitely presented subgroups of automatic groups and their isoperimetric functions
Gilbert Baumslag, Martin Bridson, Charles Miller +1
We describe a general technique for embedding certain amalgamated products into direct products. This technique provides us with a way of constructing a host of finitely presented…
Comment on ``Observation of the quantum Hall effect in a strongly localized two-dimensional system''
S. V. Kravchenko
In a recent Rapid Communication ``Observation of the quantum Hall effect in a strongly localized two-dimensional system,'' Shahar, Tsui, and Cunningham reported a disorder --…
A Tverberg-type result on multicolored simplices
János Pach
Let be pairwise disjoint -element point sets in general position in -space. It is shown that there exist a point and suitable subsets $Q_i\subs…
W_\infty and w_\infty Gauge Theories and Contraction
An. Kavalov, B. Sakita
We present a general method of constructing Winf and winf gauge theories in terms of d+2 dimensional local fields. In this formulation the \Winf gauge theory Lagrangians involve no…
Duality in deformed coset fermionic models
D. C. Cabra, E. F. Moreno
We study the -parafermion model perturbed by its first thermal operator. By formulating the theory in terms of a (perturbed) fermionic coset model we show that the mo…
A Simple Model for Deep Bed Filtration
Jysoo Lee, Joel Koplik
We present a simple model for deep bed filtration, where particles suspended in a fluid are trapped while passing through a porous filter. A steady state of the model is reached wh…
