On rime Ansatz
Oleg Ogievetsky, Todor Popov
The ice Ansatz on matrix solutions of the Yang-Baxter equation is weakened to a condition which we call rime. Generic rime solutions of the Yang-Baxter equation are described. We p…
Crystal growth and elasticity
P. Muller
The purpose of this paper is to review some elasticity effects in epitaxial growth. We start by a description of the main ingredients needed to describe elasticity effects (elastic…
LQG vertex with finite Immirzi parameter
Jonathan Engle, Etera Livine, Roberto Pereira +1
We extend the definition of the "flipped" loop-quantum-gravity vertex to the case of a finite Immirzi parameter. We cover the Euclidean as well as the Lorentzian case. We show that…
Cosmological constant and lensing
Thomas Schucker
The effect of the cosmological constant on the curvature of light due to an isolated spherical mass is recalculated without using the lens equation and compared to a lensing cluste…
First measurement of the forward-backward charge asymmetry in top quark pair production
D0 Collaboration, V. M. Abazov
We present the first measurement of the integrated forward-backward charge asymmetry in top-antitop quark pair (ttbar) production in proton-antiproton collisions in the lepton plus…
Search for ZZ and Zγ^* production in p-barp collisions at sqrt(s) = 1.96 TeV and limits on anomalous ZZZ and ZZγ^* couplings
D0 Collaboration, V. Abazov
We present a study of four muon, four electron, and two muon two electron events using 1 fb^(-1) of data collected with the D0 detector at the Fermilab Tevatron p-barp Collider at…
Search for squarks and gluinos in events with jets and missing transverse energy using 2.1 fb-1 of ppbar collision data at sqrt(s)=1.96 TeV
D0 Collaboration, V. Abazov
A data sample corresponding to an integrated luminosity of 2.1 fb-1 collected by the D0 detector at the Fermilab Tevatron Collider was analyzed to search for squarks and gluinos pr…
Measurement of the B0_s semileptonic branching ratio to an orbitally excited D_s** state, Br(B0_s -> Ds1(2536) mu nu)
D0 Collaboration, V. Abazov
In a data sample of approximately 1.3 fb-1 collected with the D0 detector between 2002 and 2006, the orbitally excited charm state D_s1(2536) has been observed with a measured mass…
Spectral Properties of a Magnetic Quantum Hamiltonian on a Strip
Philippe Briet, Georgi Raikov, Eric Soccorsi
We consider a 2D Schroedinger operator H0 with constant magnetic field, on a strip of finite width. The spectrum of H0 is absolutely continuous, and contains a discrete set of thre…
Nombres de Bernoulli et une formule de Ramanujan
Oleg Ogievetsky, Vadim Schechtman
In the first part we establish a connection between the Euler-Maclaurin summation formula and the Rota-Baxter functional equation. In the second part we give a simple proof of a fo…
Horizontal Dehn Surgery and genericity in the curve complex
Martin Lustig, Yoav Moriah
We introduce a general notion of "genericity" for countable subsets of a space with Borel measure, and apply it to the set of vertices in the curve complex of a surface S, interpre…
Intersection form, laminations and currents on free groups
Ilya Kapovich, Martin Lustig
Let be a free group of rank , let be a geodesic current on and let be an -tree with a very small isometric action of . We prove that the…
Space and time as containers, Space divisibility, and Unrepeatability of events
Mauricio Mondragon, Luis Lopez
Our main purpose here is to study some qualitative aspects of space and time. These include the notion of space and time regarded as the containers of respectively bodies and event…
Geometric Intersection Number and analogues of the Curve Complex for free groups
Ilya Kapovich, Martin Lustig
For the free group of finite rank we construct a canonical Bonahon-type continuous and -invariant \emph{geometric intersection form} \[ <, >: \bar{cv}(…

We report a search for R-parity violating production and decay of sneutrino particles in the e+mu final state with 1.04+-0.06 fb-1 of data collected with the D0 detector at the Fer…
Directive Emission from Defect-Free Dodecagonal Photonic Quasicrystals: A Leaky-Wave Characterization
Alessandro Micco, Vincenzo Galdi, Filippo Capolino +4
In this paper, we study the radiation from embedded sources in two-dimensional finite-size "photonic-quasicrystal" (PQC) slabs made of dielectric rods arranged according to a 12-fo…
Electron polarizability of crystalline solids in quantizing magnetic fields and topological gap numbers
Pavel Streda, Thibaut Jonckheere, Thierry Martin
A theory of the static electron polarizability of crystals whose energy spectrum is modified by quantizing magnetic fields is presented. It is argued that The polarizability is str…

On the energy growth of some periodically driven quantum systems with shrinking gaps in the spectrum
Pierre Duclos, Ondra Lev, Pavel Stovicek
We consider quantum Hamiltonians of the form H(t)=H+V(t) where the spectrum of H is semibounded and discrete, and the eigenvalues behave as E_n~n^α, with 0<α<1. In particular, the…
