V. wurde im Fr{\"u}hjahr 1995 gegr{\"u}ndet. Er hat es sich zur Aufgabe gemacht, die Erforschung des Milit{\"a}rs im Rahmen der fr{\"u}hneuzeitlichen Geschichte zu bef{\"o}rdern und zugleich das Bewusstsein der Fr{\"u}hneuzeit-HistorikerInnen f{\"u}r die Bedeutung des Milit{\"a}rs in all seinen Funktionen zu wecken. Das Milit{\"a}r steht somit als soziale Gruppe selbst im Mittelpunkt der Aktivit{\"a}ten des Arbeitskreises, wird aber auch in seinen Wirkungen und Repr{\"a}sentationen thematisiert. Ziel ist es, die Rolle des Milit{\"a}rs als Teil der fr{\"u}hneuzeitlichen Gesellschaft umfassend herauszuarbeiten und zu w{\"u}rdigen. Insofern versteht der AMG seine Arbeit nicht nur als Beitrag zur Milit{\"a}rgeschichte, sondern vor allem als Beitrag zur Geschichte der Fr{\"u}hen Neuzeit insgesamt. Der Arbeitskreis bietet ein Diskussions- und Informationsforum durch die Organisation von Tagungen, die Herausgabe der Schriftenreihe ‚Herrschaft und soziale Systeme in der Fr{\"u}hen Neuzeit', die Zeitschrift ‚Milit{\"a}r und Gesellschaft in der Fr{\"u}hen Neuzeit' und die Mailingliste mil-fnz.}, language = {de} } @article{KaeserBascheraKohnetal.2013, author = {K{\"a}ser, Tanja and Baschera, Gian-Marco and Kohn, Juliane and Kucian, Karin and Richtmann, Verena and Grond, Ursina and Gross, Markus and von Aster, Michael G.}, title = {Design and evaluation of the computer-based training program Calcularis for enhancing numerical cognition}, series = {Frontiers in psychology}, volume = {4}, journal = {Frontiers in psychology}, number = {31}, publisher = {Frontiers Research Foundation}, address = {Lausanne}, issn = {1664-1078}, doi = {10.3389/fpsyg.2013.00489}, pages = {13}, year = {2013}, abstract = {This article presents the design and a first pilot evaluation of the computer-based training program Calcularis for children with developmental dyscalculia (DD) or difficulties in learning mathematics. The program has been designed according to insights on the typical and atypical development of mathematical abilities. The learning process is supported through multimodal cues, which encode different properties of numbers. To offer optimal learning conditions, a user model completes the program and allows flexible adaptation to a child's individual learning and knowledge profile. Thirty-two children with difficulties in learning mathematics completed the 6-12-weeks computer training. The children played the game for 20 min per day for 5 days a week. The training effects were evaluated using neuropsychological tests. Generally, children benefited significantly from the training regarding number representation and arithmetic operations. Furthermore, children liked to play with the program and reported that the training improved their mathematical abilities.}, language = {en} } @article{GrossMuellerColbecketal.2010, author = {Gross, David and Mueller, Markus and Colbeck, Roger and Dahlsten, Oscar C.

However, quantum correlations are not maximally nonlocal, and it is natural to ask whether there are compelling reasons for rejecting theories in which stronger violations are possible. To shed light on this question, we consider post-quantum theories in which maximally nonlocal states ( nonlocal boxes) occur. We show that reversible transformations in such theories are trivial: they consist solely of local operations and permutations of systems. In particular, no correlations can be created; nonlocal boxes cannot be prepared from product states and classical computers can efficiently simulate all such processes.}, language = {en} } @article{MuellerGrossEisert2011, author = {M{\"u}ller, Markus P. and Gross, David and Eisert, Jens}, title = {Concentration of Measure for Quantum States with a Fixed Expectation Value}, series = {Communications in mathematical physics}, volume = {303}, journal = {Communications in mathematical physics}, number = {3}, publisher = {Springer}, address = {New York}, issn = {0010-3616}, doi = {10.1007/s00220-011-1205-1}, pages = {785 -- 824}, year = {2011}, abstract = {Given some observable H on a finite-dimensional quantum system, we investigate the typical properties of random state vectors vertical bar psi >> that have a fixed expectation value < psi vertical bar H vertical bar psi > = E with respect to H. Under some conditions on the spectrum, we prove that this manifold of quantum states shows a concentration of measure phenomenon: any continuous function on this set is almost everywhere close to its mean. We also give a method to estimate the corresponding expectation values analytically, and we prove a formula for the typical reduced density matrix in the case that H is a sum of local observables. We discuss the implications of our results as new proof tools in quantum information theory and to study phenomena in quantum statistical mechanics. As a by-product, we derive a method to sample the resulting distribution numerically, which generalizes the well-known Gaussian method to draw random states from the sphere.}, language = {en} }
