We find that the octadecylsilane-conjugated gold NPs stabilize both the enantiotropic nematic and the monotropic smectic-A phases of the LC host with a maximum stabilization of 2 ° C for the nematic and 3.5 ° C for the smectic-A phases for the mixture containing 1 wt% of the silanized particles. The same mixture shows the lowest values for the Fréedericksz transition threshold voltage and the highest value for the dielectric anisotropy. Generally, all NP-containing mixtures, except mixtures with NP concentrations exceeding 5 wt%, reduce the threshold voltage, increase the dielectric anisotropy and reduce both rise and decay time; the latter particularly at temperatures at least 10 ° C below the isotropic–nematic phase transition on cooling. }}, author = {{Mirzaei, Javad and Urbanski, Martin and Kitzerow, Heinz-Siegfried and Hegmann, Torsten}}, issn = {{1364-503X}}, journal = {{Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences}}, keywords = {{General Physics and Astronomy, General Engineering, General Mathematics}}, number = {{1988}}, publisher = {{The Royal Society}}, title = {{{Hydrophobic gold nanoparticles via silane conjugation: chemically and thermally robust nanoparticles as dopants for nematic liquid crystals}}}, doi = {{10.1098/rsta.2012.0256}}, volume = {{371}}, year = {{2013}}, } @article{39719, author = {{Vollbrecht, Joachim and Kasdorf, Olga and Quiring, Viktor and Suche, Hubertus and Bock, Harald and Kitzerow, Heinz-Siegfried}}, issn = {{0003-6951}}, journal = {{Applied Physics Letters}}, keywords = {{Physics and Astronomy (miscellaneous)}}, number = {{4}}, publisher = {{AIP Publishing}}, title = {{{Microresonator-enhanced electroluminescence of an organic light emitting diode based on a columnar liquid crystal}}}, doi = {{10.1063/1.4816425}}, volume = {{103}}, year = {{2013}}, } @inproceedings{41411, author = {{Beck, Karin and Gunkel, Marjaana and Seifert, Andreas and Schütz, Julia and Scharlau, Ingrid}}, booktitle = {{DGHD-Tagung „Professionalisierung der Hochschuldidaktik”}}, location = {{Magdeburg}}, title = {{{Das Leuphana College: Ein in Europa einzigartiges Hochschulmodell – Studienstruktur.}}}, year = {{2013}}, } @inproceedings{41413, author = {{Seifert, Andreas and Schütz, Julia and Gunkel, Marjaana and Beck, Karin and Balsam, Rebecca and Newig, Jens and Hellmann, Karina and Teigeler, Mareike}}, booktitle = {{DGHD-Tagung „Professionalisierung der Hochschuldidaktik”}}, location = {{Magdeburg}}, title = {{{Das Leuphana College: Ein in Europa einzigartiges Hochschulmodell – Innovative hochschuldidaktische Veranstaltungsformate.}}}, year = {{2013}}, } @inproceedings{41415, author = {{Seifert, Andreas}}, booktitle = {{AEPF-Tagung „Empirische Bildungsforschung und evidenzbasierte Reformen im Bildungswesen”}}, location = {{Dortmund}}, title = {{{Qualitätssicherung im bildungswissenschaftlichen Studium – methodologische Überlegungen.}}}, year = {{2013}}, } @inproceedings{41414, author = {{Seifert, Andreas}}, booktitle = {{Spring School der Forschungsgruppe Schul- und Unterrichtsentwicklung „Professio-nalisierung von Lehrkräften”}}, location = {{Erfurt}}, title = {{{Erwerben Lehramtsstudierende pädagogisches Professionswissen?}}}, year = {{2013}}, } @inproceedings{41353, author = {{Gunkel, Marjaana and Schütz, Julia and Seifert, Andreas and Scharlau, Ingrid and Beck, Karin and Heuer, Claudia}}, booktitle = {{INTED2013 Conference Proceedings: 7th International Technology, Education and Development Conference March 4th-6th, 2013 – Valencia, Spain}}, location = {{Valencia}}, pages = {{2510--2517}}, title = {{{A New Model of Higher Education in the European Context - The Leuphana Experience.}}}, year = {{2013}}, } @inproceedings{41477, author = {{Seifert, Andreas}}, booktitle = {{Kompetenzmessung und -modellierung in den Fachdidaktiken}}, location = {{Siegen}}, title = {{{Potential und Herausforderung von Kompetenzforschung auf der Grundlage von IRT-Modellen.}}}, year = {{2013}}, } @inproceedings{42027, author = {{Jöns, Klaus D. and Atkinson, P. and Müller, M. and Heldmaier, M. and Ulrich, S.

In the first area, we demonstrate a polynomial-time (classical) approximation algorithm for dense instances of the canonical QMA-complete quantum constraint satisfaction problem, the local Hamiltonian problem. In the opposite direction, we next introduce a quantum generalization of the polynomial-time hierarchy, and define problems which we prove are not only complete for the second level of this hierarchy, but are in fact hard to approximate. In the second area, we study variants of the interesting and stubbornly open question of whether a quantum proof system with multiple unentangled quantum provers is equal in expressive power to a proof system with a single quantum prover. Our results concern classes such as BellQMA(poly), and include a novel proof of perfect parallel repetition for SepQMA(m) based on cone programming duality. In the third area, we study non-classical quantum correlations beyond entanglement, often dubbed "non-classicality". Among our results are two novel schemes for quantifying non-classicality: The first proposes the new paradigm of exploiting local unitary operations to study non-classical correlations, and the second introduces a protocol through which non-classical correlations in a starting system can be "activated" into distillable entanglement with an ancilla system.

We then study the class BellQMA(poly), characterized by a verifier who first applies unentangled, nonadaptive measurements to each of the polynomially many proofs, followed by an arbitrary but efficient quantum verification circuit on the resulting measurement outcomes. We show that if the number of outcomes per nonadaptive measurement is a polynomially-bounded function, then the expressive power of the proof system is exactly QMA. Finally, we study a class equivalent to QMA(m), denoted SepQMA(m), where the verifier's measurement operator corresponding to outcome "accept" is a fully separable operator across the m quantum proofs.
