Local suppression of the hidden order phase by impurities in URu2Si2

We consider the effects of impurities on the enigmatic hidden order (HO) state of the heavy-fermion material URu2Si2. In particular, we focus on local effects of Rh impurities as a tool to probe the suppression of the HO state. To study local properties we introduce a lattice free energy, where the time invariant HO order parameter "psi" and local antiferromagnetic (AFM) order parameter M are competing orders. Near each Rh atom the HO order parameter is suppressed, creating a hole in which local AFM order emerges as a result of competition. These local holes are created in the fabric of the HO state like in a Swiss cheese and "filled" with droplets of AFM order. We compare our analysis with recent NMR results on URu2Si2 doped with Rh and find good agreement with the data.Comment: 8 pages, 6 figure

Crowdlending for German SMEs

Fintech is revolutionizing the financial world. And concurrently with this phenomenon, there emerges a business model that owes its novel growth above all to the rigidity of banks and new regulatory requirements since the financial crisis of 2008: Crowdlending for SMEs. In Germany, however, the new solution, which connects lenders and borrowers directly via a platform, still has start-up difficulties. Based on this, the goal of this research is to examine factors that determine the decision to adopt Crowdlending among German SMEs. Using the innovation adoption framework by Wisdom, et al. (2013), a qualitative research design is conducted to compare two groups of enterprises according to their per-ception towards the emerging financing solution. Every group consists of six participants and is created according to category, industry and the decision of having already adopted Crowdlending or not, resulting in a sample size of twelve interviewees. The study shows that although facing trust issues, factors, such as speed, low complexity and the possibility of rising awareness among SME’s customers are crucial for an adoption decision. On a company level, innovative management, the readiness to change and curiosity signifi-cantly yield a positive effect on the decision to adopt. The tendency appears to be even stronger, when the firm has recently faced a change in leadership from an older to a younger entrepreneur. While theoretically contributing to the scarce literature about Crowdlending in combination with German SMEs, it gives thought impacts to involved stakeholders.Fintech está a revolucionar o mundo financeiro. Ao mesmo tempo que ocorre este fenómeno, surge um modelo de negócio que deve o seu crescimento sobretudo à rigidez dos bancos e aos requisitos regulamentares desde a crise financeira de 2008: Crowdlend-ing para PMEs. Na Alemanha, contudo, a nova solução, que conecta credores e devedores diretamente via uma plataforma, ainda possui dificuldades iniciais. Com base nisto, o objetivo desta pesquisa passa por examinar fatores que determinam a decisão de adoptar Crowdlending entre PMEs Alemâs. Utilizando a estrutura de adoção de inovação de Wis-dom, et al. (2013), uma concepção de pesquisa qualitativa é conduzida de modo a com-parer dois grupos de empresas de acordo com a sua percepção em relação à solução fi-nanceira emergente. Todos os grupos consistem em seis participantes e é criado de acordo com categoria, indústria e a decisão de já ter ou não adotato Crowdlending, resultando numa amostra de 12 entrevistados. O estudo mostra que apesar de enfrentar questões de confiança, fatores como, rapidez, complexidade baixa e a possibilidade de conscientizar clientes de PMEs são cruciais para a decisão de adoção. A nível da empresa, inovação de gestão, a disponibilidade para mudar e a curiosidade produzem um efeito positivo na decisão de adoção. A tendência aparenta ser ainda mais forte, quando a empresa recente-mente mudou de liderança de um empreendedor mais velho para um mais novo. Ao teor-icamente contribuir para a escassa literatura sobre Crowdlending em combinação com PMEs Alemãs, impacta o pensamente dos intervenientes

How to investigate the local and global change potential of questioning sequences in executive coaching? A call for interdisciplinary research

Coaching outcome research convincingly argues that coaching is effective and facilitates  change in clients. While coaching practice literature depicts questions as key vehicle for such change, empirical findings as regards the local and global change potential of questions are so far largely missing in both (psychological) outcome research and (linguistic and psychological) process research on coaching. The local change potential of questions refers to a turn-by-turn transformation as a result of their sequentiality, the global change potential is related to the power of questions to initiate, process and finalize established phases of change. This programmatic article on questions, or rather questioning sequences, in executive coaching pursues two goals: firstly, it takes stock of available insights into questions in coaching and advocates for Conversation Analysis as a fruitful methodological framework to assess the local change potential of questioning sequences. Secondly, it points to the limitations of a local turn-by-turn approach to unravel the overall change potential of questions and calls for an interdisciplinary approach to bring both local and global effectiveness into relation. Such an approach is premised on conversational sequentiality and psychological theories of change and facilitates research on questioning sequences as both local and global agents of change across the continuum of coaching sessions. We present the TSPP Model as a first result of such an interdisciplinary cooperation

Rhombohedral R3c to orthorhombic Pnma phase transition induced by Y-doping in BiFeO3

In this work we study, by means of ab initio calculations, the structural, electronic and magnetic properties of Y-doped BiFeO3 compounds. We determine that there is a morphotropic phase boundary at an yttrium concentration of , where the structure changes from R3c to Pnma. This structural transition is driven by the chemical pressure induced by the dopant. By analyzing the evolution of the oxygen octahedral tilts we find an enhanced antiferrodistortive distortion when increasing the Y-doping, together with a reduction of the ferroelectric distorsion, that gives rise to a smaller value of the electric polarization. These cooperative effects should lead to a larger canting of the Fe magnetic moments and to a larger ferromagnetic response in the R3c phase, as it is observed in the experiments.Fil: Graf, Mónica Elisabet.
