High-speed imaging of snow saltation: wind tunnel experiments using natural snow

Michael Lehning, Daniela Brito Melo, Benjamin Andreas Walter

Drifting snow is a multi-scale process. It is composed of particles rolling and sliding along the surface, particles in saltation following short ballistic trajectories in the first 10 cm above the surface and particles in suspension at higher regions of t ...

Distributed State Estimation and Control of Autonomous Quadrotor Formations Using Exclusively Onboard Resources

Duarte Da Cruz Baptista Dias

The navigation of unmanned aerial vehicles operating in environments without global positioning systems, including global navigation satellite systems and motion capture systems, is a recent research topic, without much work reported in the literature. In ...

On Anomalous Lieb-Robinson Bounds for the Fibonacci XY Chain

Marius Christopher Lemm

We rigorously prove a new kind of anomalous (or sub-ballistic) Lieb-Robinson bound for the isotropic XY chain with Fibonacci external magnetic field at arbitrary coupling. It is anomalous in that the usual exponential decay in

Geometry of Chemical Beam Vapor Deposition System for Efficient Combinatorial Investigations of Thin Oxide Films: Deposited Film Properties versus Precursor Flow Simulations

Paul Muralt, Silviu Cosmin Sandu, Estelle Wagner, Scott Harada, Giacomo Benvenuti, Marc Jobin

An innovative deposition system has been developed to construct complex material thin films from single-element precursors by chemical beam vapor deposition (CBVD). It relies on well distributed punctual sources that emit individually controlled precursor ...

Room-Temperature Ballistic Transport in III-Nitride Heterostructures

Elison de Nazareth Matioli

Room-temperature (RT) ballistic transport of electrons is experimentally observed and theoretically investigated in III-nitrides. This has been largely investigated at low temperatures in low band gap III-V materials due to their high electron mobilities. ...

New Anomalous Lieb-Robinson Bounds in Quasiperiodic XY Chains

Marius Christopher Lemm

We announce and sketch the rigorous proof of a new kind of anomalous (or sub-ballistic) Lieb-Robinson (LR) bound for an isotropic XY chain in a quasiperiodic transversal magnetic field. Instead of the usual effective light cone |x|≤v|t|, we obtain |x|≤v|t| ...

Dynamic control of light transmission through multimode fibers

Ioannis Papadopoulos

In the present thesis we demonstrate how under the appropriate dynamic control of light propagation, multimode fibers can be transformed into deterministic optical elements that along with their ultrathin size, large number of degrees of freedom and high N ...

Nondiffusive Suprathermal Ion Transport in Simple Magnetized Toroidal Plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson

We investigate suprathermal ion dynamics in simple magnetized toroidal plasmas in the presence of electrostatic turbulence driven by the ideal interchange instability. Turbulent fields from fluid simulations are used in the nonrelativistic equation of ion ...

Investigation of suprathermal ion transport in TORPEX

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

Basic aspects of suprathermal ion transport in interchange-mode unstable plasmas are investigated in the simple toroidal plasma device TORPEX. Suprathermal ions are generated with a miniaturized lithium 6+ ion source with energies up to 1keV, and are detec ...

Band structure and quantum conductance of nanostructures from maximally localized wannier functions: The case of functionalized carbon nanotubes

Nicola Marzari

We have combined large-scale, Gamma-point electronic-structure calculations with the maximally localized Wannier functions approach to calculate efficiently the band structure and the quantum conductance of complex systems containing thousands of atoms whi ...
