Stable Spin Maps, Gromov-Witten Invariants, and Quantum Cohomology

Tyler J. Jarvis, Takashi Kimura, Arkady Vaintrob

We introduce the stack of r-spin maps. These are stable maps into a variety V from n-pointed algebraic curves of genus g, with the additional data of an r-spin structure on the cur…

Top Physics

Elizabeth H. Simmons

The Run I experiments at the Fermilab Tevatron Collider discovered the top quark and provided first measurements of many of its properties. Run II (and eventually the LHC and NLC e…

Fractional Electrons in Liquid Helium?

R. Jackiw, C. Rebbi, J. R. Schrieffer

We argue that electrons in liquid helium bubbles are not fractional, they are entangled.

Thermodynamically Important Contacts in Folding of Model Proteins

Antonio Scala, Nikolay V. Dokholyan, Sergey V. Buldyrev +1

We introduce a quantity, the entropic susceptibility, that measures the thermodynamic importance-for the folding transition-of the contacts between amino acids in model proteins. U…

The Dynamics of Efficiency: A Simple Model

S. N. Majumdar, P. L. Krapivsky

We propose a simple model that describes the dynamics of efficiencies of competing agents. Agents communicate leading to increase of efficiencies of underachievers, and an efficien…

CDW, Superconductivity and Anomalous Metallic Behavior in 2D Transition Metal Dichalcogenides

Antonio H. Castro Neto

We propose a theory for quasi-two-dimensional transition metal dichalcogenides that provides a unified microscopic picture of the charge density wave (CDW) and superconducting phas…

suppression in co-doped striped cuprates

C. Morais Smith, A. H. Castro Neto, A . V. Balatsky

We propose a model that explains the reduction of due to the pinning of stripes by planar impurity co-doping in cuprates. A geometrical argument about the planar fraction of…

Inherent-Structure Dynamics and Diffusion in Liquids

T. Keyes, J. Chowdhary

The self-diffusion constant D is expressed in terms of transitions among the local minima of the potential (inherent structure, IS) and their correlations. The formulae are evaluat…

Composite Scalars at LEP: Constraining Technicolor Theories

Kevin R. Lynch, Elizabeth H. Simmons

LEPI and LEPII data can be used to constrain technicolor models with light, neutral pseudo-Nambu-Goldstone bosons, Pa. We use published limits on branching ratios and cross section…

Anti-B-B Mixing Constrains Topcolor-Assisted Technicolor

Gustavo Burdman, Kenneth Lane, Tonguc Rador

We argue that extended technicolor augmented with topcolor requires that all mixing between the third and the first two quark generations resides in the mixing matrix of left-hande…

Byzantine Agreement with Faulty Majority using Bounded Broadcast

Jeffrey Considine, Leonid A. Levin, David Metcalf

Byzantine Agreement introduced in [Pease, Shostak, Lamport, 80] is a widely used building block of reliable distributed protocols. It simulates broadcast despite the presence of fa…

The Tale of One-way Functions

Leonid A. Levin

The existence of one-way functions is arguably the most important problem in computer theory. The article discusses and refines a number of concepts relevant to this problem. For i…

Average Time Spent by Levy Flights and Walks on an Interval with Absorbing Boundaries

S. V. Buldyrev, S. Havlin, A. Ya. Kazakov +4

We consider a Levy flyer of order alpha that starts from a point x0 on an interval [O,L] with absorbing boundaries. We find a closed-form expression for the average number of fligh…

Characterization of Sleep Stages by Correlations of Heartbeat Increments

Jan W. Kantelhardt, Yosef Ashkenazy, Plamen Ch. Ivanov +5

We study correlation properties of the magnitude and the sign of the increments in the time intervals between successive heartbeats during light sleep, deep sleep, and REM sleep us…

Degree Distributions of Growing Networks

P. L. Krapivsky, G. J. Rodgers, S. Redner

The in-degree and out-degree distributions of a growing network model are determined. The in-degree is the number of incoming links to a given node (and vice versa for out-degree.…

Semileptonic Form-factors from B-> K* gamma Decays in the Large Energy Limit

Gustavo Burdman, Gudrun Hiller

Making use of the measurement of the branching ratio together with the relations following from the limit of high recoil energy, we obtain stringent constraints on the…

Compatible sequences and a slow Winkler percolation

Peter Gacs

Two infinite 0-1 sequences are called compatible when it is possible to cast out 0's from both in such a way that they become complementary to each other. Answering a question of P…

Exact results and approximation schemes for the Schwinger model with the overlap Dirac operator

L. Giusti, C. Hoelbling, C. Rebbi

We propose new techniques to implement numerically the overlap-Dirac operator which exploit the physical properties of the underlying theory to avoid nested algorithms. We test the…
