Chaotic Dirac billiard in graphene quantum dots

L. A. Ponomarenko, F. Schedin, M. I. Katsnelson +4

We report on transport characteristics of quantum dot devices etched entirely in graphene. At large sizes, they behave as conventional single-electron transistors, exhibiting perio…

A Measurement of the Branching Fractions of exclusive Bbar -> D(*)(pi)l-nubar Decays in Events with a Fully Reconstructed B Meson

The BABAR Collaboration, B. Aubert

We report a measurement of the branching fractions for Bbar -> D(*)(pi)l-nubar decays based on 341.1 fb-1 of data collected at the Upsilon(4S) resonance with the babar detector at…

Time-dependent Dalitz plot analysis of B0 -> D-(+) K0 Pi+(-) decays

The BABAR Collaboration, B. Aubert

We present for the first time a measurement of the weak phase 2b+g obtained from a time-dependent Dalitz plot analysis of B^0 -> D-(+) K0 Pi+(-) decays. Using a sample of approxima…

Predicting the Last Zero of Brownian Motion with Drift

J. du Toit, G. Peskir, A. N. Shiryaev

Given a standard Brownian motion $B^{μ} = (B_{t}^{μ})_{0 \leq t \leq T}$ with drift $μ \in I R$ and letting $g$ denote the last zero of $B^{μ}$ before $T$ , we consider the optimal prediction probl…

A note on the supremum of a stable process

R. A. Doney

If $X$ is a spectrally positive stable process of index $α \in (1, 2)$ whose Lévy measure has density $c x^{- α - 1}$ on $(0, \infty),$ and $S_{1} = sup_{0 < t \leq 1} X_{t},$ it is known that $P(S_…

Rapid paths in von Neumann-Gale dynamical systems

Wael Bahsoun, Igor V. Evstigneev, Michael I. Taksar

The paper examines random dynamical systems related to the classical von Neumann and Gale models of economic growth. Such systems are defined in terms of multivalued operators in s…
