Photoemission-induced gating of topological insulators

The recently discovered topological insulators exhibit topologically protected metallic surface states which are interesting from the fundamental point of view and could be useful for various applications if an appropriate electronic gating can be realized ...

Surface-Confined Metal?Organic Nanostructures from Co-Directed Assembly of Linear Terphenyl-dicarbonitrile Linkers on Ag(111)

Klaus Kern, Harald Brune, Uta Schlickum, Régis Decker

A detailed structural analysis of the surface supported self-assembly of terphenyl-4,4′′-dicarbonitrile molecules (NC−Ph3−CN) linked by Co adatoms on Ag(111) reveals different surface patterns depending on the constraints applied to the system. Without con ...

Re-Animating Greg Lynn's Embryological House: A Case Study in Digital Design Preservation

Guillaume Labelle

Greg Lynn's Embryological House was an early work of digital architecture: a work in which the computer was a fundamental part of the design process. It was the subject of a case study in digital preservation by the Daniel Langlois Foundation's project for ...

Concurrent Programming Paradigms, A Comparison in Scala

Rachid Guerraoui, Martin Odersky, Mohsen Lesani

There is a rapid rise of multi-cores in recent hardware architectures. To exploit computational power of multi-core architectures, software should shift to be as concurrent as possible; and therefore should have concurrency control mechanisms. There are di ...

Cayley Graphs and growth of groups

Nathalie Pellet

One of the most fundamental objects in algebra is the group. There exist plenty of different groups. In the following article we consider some free abelian gorups, cyclic groups, free groups and fundamental groups as well as the products of groups and draw ...

Trace coordinates of Teichmüller spaces of Riemann surfaces

Thomas Gauglhofer

Using an algebraic formalism based on matrices in SL(2,R), we explicitly give the Teichmüller spaces of Riemann surfaces of signature (0,4) (X pieces), (1,2) ("Fish" pieces) and (2,0) in trace coordinates. The approach, based upon gluing together two build ...

Trace coordinates of Teichmüller space of Riemann surfaces of signature $(0,4)$

Klaus-Dieter Semmler, Thomas Gauglhofer

Summary: We explicitly give

calT

, the Teichmüller space of four-holed spheres (which we call

X

pieces) in trace coordinates, as well as its modular group and a fundamental domain for the action of this group on

calT

which is its moduli space. As a co ...

Independently Extensible Solutions to the Expression Problem

Martin Odersky, Matthias Zenger

The expression problem is fundamental for the development of extensible software. Many (partial) solutions to this important problem have been proposed in the past. None of these approaches solves the problem of using different, independent extensions jo ...

Propriétés homotopiques du complexe de Quillen du groupe symétrique

The fundamental group of the Quillen complex of the symmetric group is studied and the cases where the complex is simply-connected are determined. Other results concerning the homology groups are also proved. ...

Preisach Modelling: Symmetry Implementation and Frequency Analysis

Marten Sjöström

The paper contains an analysis of the classical Preisach Model from a symmetry and a frequency point of view. Increasing and decreasing inputs have no fundamental difference, which leads to a simplified implementation by changing indices. Symmetry implies ...
