Kinetics of Ferromagnetic Ordering in 3D Ising Model: Do we understand the case of zero temperature quench?

We study phase ordering dynamics in the three-dimensional nearest-neighbor Ising model, following rapid quenches from infinite to zero temperature. Results on various aspects, viz., domain growth, persistence, aging and pattern, have been obtained via the Glauber Monte Carlo simulations of the model on simple cubic lattice. These are analyzed via state-of-the-art methods, including the finite-size scaling, and compared with those for quenches to a temperature above the roughening transition. Each of these properties exhibit remarkably different behavior at the above mentioned final temperatures. Such a temperature dependence is absent in the two-dimensional case for which there is no roughening transition

Coarsening in 3D Nonconserved Ising Model at Zero Temperature: Anomalies in structure and relaxation of order-parameter autocorrelation

Via Monte Carlo simulations we study pattern and aging during coarsening in nonconserved nearest neighbor Ising model, following quenches from infinite to zero temperature, in space dimension $d=3$. The decay of the order-parameter autocorrelation function is observed to obey a power-law behavior in the long time limit. However, the exponent of the power-law, estimated accurately via a state-of-art method, violates a well-known lower bound. This surprising fact has been discussed in connection with a quantitative picture of the structural anomaly that the 3D Ising model exhibits during coarsening at zero temperature. These results are compared with those for quenches to a temperature above that of the roughening transition.Comment: 15 pages, 6 figure

Using Narratives in Creativity Research: Handling the Subjective Nature of Creative Process

For most of us, creative processes are those which can produce outcomes that are capable of being judged as creative. The outcome-centric recognition of creativity has heavily downplayed the process-perspective of creativity in organizations. Influenced significantly by individual and social subjectivities, creative processes are difficult to enquire on the basis of positivist approaches presently dominating creativity research. Use of narrative methodology in creativity research is proposed as a strategy for not just handling the subjectivities but also for making meaning from them as well as from participants\u27 emotions. Antenarratives can help to enrich the narrated storyline, and personal narratives of the researcher allows to tie back the subjectivities through co-created meanings. The article aspires to invigorate attention towards the foundations of creativity research that has offered little scope for research paradigms that are beyond the objective-positivist tradition. Consequently, it urges the research community to seek suitable methodologies like the narrative which promises to explore the process-perspective of creativity and enlarge our organizational understanding of creativity

Embodying Change at Work: An Autoethnography in the Indian Public Sector

Beyond the macro picture of change in the Indian public sector triggered by economic deregulation and restructuration, the variegated experiences of employees exposed to organizational changes remain hidden and masked. Through a reflexive inquiry about my experience of participating in a managerial implementation of a performance management system in an Indian public sector organization, I write this autoethnography to bring forward a personal narrative of embodying change at work. I do this by revealing how my cultural, social, and political experiences during that episode of change were manifestations of being and constituting organizationally intended as well as non-intended changes. The writing process involved in bringing out the personal narrative unravels the contours of my relationship with organizational actors such as the employees, the union, and the management, to eventually understand their impact on my experience of change. The narrative analysis of the ethnographic memoir has helped me consider my insider knowledge, realization, and reflection as opportunities to retell the macro (view of change) in terms of the interconnected individual subjectivities. Thus the autoethnographic effort is directed to tease out the associated meanings of embodying change at work by thinking with the narrative, rather than using the narrative to think. The broader goal of this inquiry is to draw ethnographic implications for working lives exposed to organizational changes
