Wreath product decompositions for triangular matrix semigroups
Mark Kambites, Benjamin Steinberg
We consider wreath product decompositions for semigroups of triangular matrices. We exhibit an explicit wreath product decomposition for the semigroup of all n-by-n upper triangula…
Enhancement of entanglement in one-dimensional disordered systems
R. Lopez-Sandoval, Martin E. Garcia
The pairwise quantum entanglement of sites in disordered electronic one-dimensional systems (rings) is studied. We focus on the effect of diagonal and off diagonal disorder on the…
Energy resolved STM mapping of C on metal surfaces: A theoretical study
Mario De Menech, Ulf Saalmann, Martin E. Garcia
We present a detailed theoretical study of scanning tunneling imaging and spectroscopy of \Csixty on silver and gold surfaces, motivated by the recent experiments and discussion by…
Modeling of droplet breakup in a microfluidic T--shaped junction with a phase--field model
Mario De Menech
A phase--field method is applied to the modeling of flow and breakup of droplets in a T--shaped junction in the hydrodynamic regime where capillary and viscous stresses dominate ov…
Uniform decision problems in automatic semigroups
Mark Kambites, Friedrich Otto
We consider various decision problems for automatic semigroups, which involve the provision of an automatic structure as part of the problem instance. With mild restrictions on the…
Automatic Rees matrix semigroups over categories
Mark Kambites
We consider the preservation of the properties of automaticity and prefix-automaticity in Rees matrix semigroups over semigroupoids and small categories. Some of our results are ne…
Concept of deterministic single ion doping with sub-nm spatial resolution
J. Meijer, T. Vogel, B. Burchard +9
We propose a method for deterministic implantation of single atoms into solids which relies on a linear ion trap as an ion source. Our approach allows a deterministic control of th…
Word problems recognisable by deterministic blind monoid automata
Mark Kambites
We consider blind, deterministic, finite automata equipped with a register which stores an element of a given monoid, and which is modified by right multiplication by monoid elemen…
Algebraic tools for dealing with the atomic shell model. I. Wavefunctions and integrals for hydrogen--like ions
Andrey Surzhykov, Peter Koval, Stephan Fritzsche
Today, the 'hydrogen atom model' is known to play its role not only in teaching the basic elements of quantum mechanics but also for building up effective theories in atomic and mo…
