Continuously Varying Growth Exponent in Kinetics of Vapor-Solid Phase Transition
 

Speaker: Subir Das
(JNCASR, Bengaluru)
 

Date: November 28, 2017 (Tuesday)
Time: 16:00 hrs  (4:00 pm)
Venue: Seminar Room, First Floor,School of Physical Sciences (SPS), JNU
 

Abstract: In this talk I will discuss results for kinetics of vapor-solid transitions (the solid phase having only quasi-long-range order) from molecular dynamics simulations of a single component Lennard-Jones system in space dimension d=2. Having been quenched from high temperature to the vapor-solid coexistence region, the system evolves via formation and growth of fractal domains of the solid phase. For very low overall density, the morphology consists of isolated fractal clusters which exhibit ballistic motion in the vapor background and grow via sticky collisions among them, the average mass following power-law with time. The exponent of the power-law varies continuously with the quench depth, due to change in fractality. These molecular dynamics simulation results are understood via appropriate theoretical argument.

A warm welcome to the modified and updated website of the Centre for East Asian Studies. The East Asian region has been at the forefront of several path-breaking changes since 1970s beginning with the redefining the development architecture with its State-led development model besides emerging as a major region in the global politics and a key hub of the sophisticated technologies. The Centre is one of the thirteen Centres of the School of International Studies, Jawaharlal Nehru University, New Delhi that provides a holistic understanding of the region.

Initially, established as a Centre for Chinese and Japanese Studies, it subsequently grew to include Korean Studies as well. At present there are eight faculty members in the Centre. Several distinguished faculty who have now retired include the late Prof. Gargi Dutt, Prof. P.A.N. Murthy, Prof. G.P. Deshpande, Dr. Nranarayan Das, Prof. R.R. Krishnan and Prof. K.V. Kesavan. Besides, Dr. Madhu Bhalla served at the Centre in Chinese Studies Programme during 1994-2006. In addition, Ms. Kamlesh Jain and Dr. M. M. Kunju served the Centre as the Documentation Officers in Chinese and Japanese Studies respectively.

The academic curriculum covers both modern and contemporary facets of East Asia as each scholar specializes in an area of his/her interest in the region. The integrated course involves two semesters of classes at the M. Phil programme and a dissertation for the M. Phil and a thesis for Ph. D programme respectively. The central objective is to impart an interdisciplinary knowledge and understanding of history, foreign policy, government and politics, society and culture and political economy of the respective areas. Students can explore new and emerging themes such as East Asian regionalism, the evolving East Asian Community, the rise of China, resurgence of Japan and the prospects for reunification of the Korean peninsula. Additionally, the Centre lays great emphasis on the building of language skills. The background of scholars includes mostly from the social science disciplines; History, Political Science, Economics, Sociology, International Relations and language.

Several students of the centre have been recipients of prestigious research fellowships awarded by Japan Foundation, Mombusho (Ministry of Education, Government of Japan), Saburo Okita Memorial Fellowship, Nippon Foundation, Korea Foundation, Nehru Memorial Fellowship, and Fellowship from the Chinese and Taiwanese Governments. Besides, students from Japan receive fellowship from the Indian Council of Cultural Relations.
