Free-Boundary Dynamics in Elasto-plastic Amorphous Solids: The Circular Hole Problem

Eran Bouchbinder, J. S. Langer, Ting-Shek Lo +1

We develop an athermal shear-transformation-zone (STZ) theory of plastic deformation in spatially inhomogeneous, amorphous solids. Our ultimate goal is to describe the dynamics of…

Massive perturbers in the galactic center

Hagai B. Perets, Clovis Hopman, Tal Alexander

We investigate the role of massive perturbers, such as giant molecular clouds or stellar clusters, in supplying low-angular momentum stars that pass very close to the central massi…

Inclusive Production of Charged Hadrons in Photon-Photon Collisions

The OPAL collaboration

The inclusive production of charged hadrons in the collisions of quasi-real photons e+e- -> e+e- +X has been measured using the OPAL detector at LEP. The data were taken at e+e- ce…

Phase lapses in transmission through interacting two-level quantum dots

C. Karrasch, T. Hecht, A. Weichselbaum +3

We investigate the appearance of pi lapses in the transmission phase theta of a two-level quantum dot with Coulomb interaction U. Using the numerical and functional renormalization…

On the hyperplane conjecture for random convex sets

Bo'az Klartag, Gady Kozma

Let N > n, and denote by K the convex hull of N independent standard gaussian random vectors in an n-dimensional Euclidean space. We prove that with high probability, the isotropic…

The use of cluster quality for track fitting in the CSC detector

Erez Etzion, David Primor, Giora Mikenberg +2

The new particle accelerators and its experiments create a challenging data processing environment, characterized by large amount of data where only small portion of it carry the e…

Long-Range Effects in Layered Spin Structures

Alessandro Campa, Ramaz Khomeriki, David Mukamel +1

We study theoretically layered spin systems where long-range dipolar interactions play a relevant role. By choosing a specific sample shape, we are able to reduce the complex Hamil…

Temperature dependence of spin susceptibility in two-dimensional Fermi liquid systems

A. Shekhter, A. M. Finkel'stein

We consider the non-analytic terms in the spin susceptibility arising as a result of rescaterring of pairs of quasiparticles. We emphasize the importance of rescattering in the Coo…

Precision Measurement of the Decay Rate of 7Be in Host Materials

Y. Nir-El, G. Haquin, Z. Yungreiss +14

A controlled and precise determination of the cross-sections of the fusion reactions 7Be(p,gamma)8B and 3He(4He,gamma)7Be, which play an important role in determining the solar neu…

Cooling in a Bistable Optical Cavity

Mark Y. Vilensky, Yehiam Prior, Ilya Sh. Averbukh

We propose a generic approach to nonresonant laser cooling of atoms/molecules in a bistable optical cavity. The method exemplifies a photonic version of Sisyphus cooling, in which…

Bottleneck crossover between classical and quantum superfluid turbulence

Victor S. L'vov, Sergei V. Nazarenko, Oleksii Rudenko

We consider superfluid turbulence near absolute zero of temperature generated by classical means, e.g. towed grid or rotation but not by counterflow. We argue that such turbulence…

Clustering of matter in waves and currents

M. Vucelja, G. Falkovich, I. Fouxon

The growth rate of small-scale density inhomogeneities (the entropy production rate) is given by the sum of the Lyapunov exponents in a random flow. We derive an analytic formula f…

Tightness for a family of recursion equations

Maury Bramson, Ofer Zeitouni

In this paper we study the tightness of solutions for a family of recursion equations. These equations arise naturally in the study of random walks on tree-like structures. Example…

Hurewicz sets of reals without perfect subsets

Dušan Repovš, Boaz Tsaban, Lyubomyr Zdomskyy

We show that even for subsets X of the real line which do not contain perfect sets, the Hurewicz property does not imply the property S1(Gamma,Gamma), asserting that for each count…

Supercritical stability, transitions and (pseudo)tachyons

Ofer Aharony, Eva Silverstein

Highly supercritical strings (c much greater than 15) with a time-like linear dilaton provide a large class of solutions to string theory, in which closed string tachyon condensati…

The importance of N2 leptogenesis

Guy Engelhard, Yuval Grossman, Enrico Nardi +1

We argue that fast interactions of the lightest singlet neutrino would project part of a preexisting lepton asymmetry onto a direction that is protected from wash…

Shot Noise in Anyonic Mach-Zehnder Interferometer

D. E. Feldman, Yuval Gefen, Alexei Kitaev +2

We show how shot noise in an electronic Mach-Zehnder interferometer in the fractional quantum Hall regime probes the charge and statistics of quantum Hall quasiparticles. The depen…
