Electromagnetic wave scattering from a random layer with rough interfaces II: Diffusive intensity

A. Soubret, G. Berginc

A general approach for the calculation of the incoherent intensity scattered by a random medium with rough boundaries has been developed using a Green function formalism. The rando…

Signatures of spin-charge separation in double--quantum-wire tunneling

Yaroslav Tserkovnyak, Bertrand I. Halperin, Ophir M. Auslaender +1

We present evidence for spin-charge separation in the tunneling spectrum of a system consisting of two quantum wires connected by a long narrow tunnel junction at the edge of a GaA…

On the Ramification of Hecke Algebras at Eisenstein Primes

Frank Calegari, Matthew Emerton

Using the modularity technique of Wiles, we study the Hecke algebra of weight 2 and prime level N localized at the Eisenstein primes. On the way, we recover some results of Mazur (…

Slopes of overconvergent 2-adic modular forms

Kevin Buzzard, Frank Calegari

The slope of a p-adic overconvergent eigenform of weight k is the p-adic valuation of its U_p eigenvalue. We find the slope of all 2-adic finite slope overconvergent eigenforms of…

2 P2P or Not 2 P2P?

Mema Roussopoulos, Mary Baker, David S. H. Rosenthal +3

In the hope of stimulating discussion, we present a heuristic decision tree that designers can use to judge the likely suitability of a P2P architecture for their applications. It…

Contact Structures with Distinct Heegaard Floer Invariants

Olga Plamenevskaya

We prove that the contact structures on Y= dX induced by non-homotopic Stein structures on the 4-manifold X have distinct Heegaard Floer invariants.

On the J-flow in higher dimensions and the lower boundedness of the Mabuchi energy

Ben Weinkove

The J-flow is a parabolic flow on Kahler manifolds. It was defined by Donaldson in the setting of moment maps and by Chen as the gradient flow of the J-functional appearing in his…

A Black Hole Life Preserver

J. Richard Gott, Deborah L. Freedman

Since no one lives forever, all a life preserver can really do is prolong life for longer than would have otherwise been the case. With this rather limited definition in mind we ex…

Observing the First Stars, One Star at a Time

Abraham Loeb

Gamma-Ray Bursts (GRBs) are believed to originate in compact remnants (black holes or neutron stars) of massive stars. Their high luminosities make them detectable out to the edge…

Euler Maclaurin with remainder for a simple integral polytope

Yael Karshon, Shlomo Sternberg, Jonathan Weitsman

We give an Euler Maclaurin formula with remainder for the sum of the values of a smooth function on the integral points in a simple integral polytope. This formula is proved by ele…

Fluctuations of radiation from a chaotic laser below threshold

E. G. Mishchenko

Radiation from a chaotic cavity filled with gain medium is considered. A set of coupled equations describing the photon density and the population of gain medium is proposed and so…

Effective very ampleness for generalized theta divisors

Eduardo Esteves, Mihnea Popa

Given a smooth projective curve X, we give effective very ampleness bounds for generalized theta divisors on the moduli spaces and of semistable vector bundl…

A Reciprocity Theorem for Monomer-Dimer Coverings

N. Anzalone, J. Baldwin, I. Bronshtein +1

The problem of counting monomer-dimer coverings of a lattice is a longstanding problem in statistical mechanics. It has only been exactly solved for the special case of dimer cover…

Elliptic curves and class field theory

Barry Mazur, Karl Rubin

Suppose is an elliptic curve defined over $\Q$. At the 1983 ICM the first author formulated some conjectures that propose a close relationship between the explicit class field…

Deformations of chiral algebras

Dimitri Tamarkin

We start studying chiral algebras (as defined by A. Beilinson and V. Drinfeld) from the point of view of deformation theory. First, we define the notion of deformation of a chiral…

Quantum Field Theory and the Space of All Lie Algebras

William Gordon Ritter

The space M_n of all isomorphism classes of n-dimensional Lie algebras over a field k has a natural non-Hausdorff topology, induced from the Segal topology by the action of GL(n).…

Inversion of adjunction for local complete intersection varieties

Lawrence Ein, Mircea Mustaţǎ

In this note we build on our previous work with Takehiko Yasuda to prove a precise version of inversion of adjunction for varieties which are local complete intersections.

Asymptotic black hole quasinormal frequencies

Lubos Motl, Andrew Neitzke

We give a new derivation of the quasinormal frequencies of Schwarzschild black holes in d>=4 and Reissner-Nordstrom black holes in d=4, in the limit of infinite damping. For Schwar…
