Ms. Sanjukta Jena, a PhD student of the Department of Physics, Central University of South Bihar, has been awarded the best paper award in an International Conference on “Advances in Spectroscopic Techniques and Materials-2024”. The conference was organized by the department of Physics, Indian Institute of Technology Dhanbad Jharkhand during January 18-20, 2024. She is working under the supervision of Dr. Vijay Raj Singh in Physics, CUSB Gaya in UGC-DAE CSR Indore sponsored project which is related to Skyrmion. She has already published this work in Physica Scripta (IOP Publisher). Ms. Jena was honoured with a certificate, memento and Cash Prize of Rs. 2000/-.
A skyrmion is a fascinating phenomenon in physics that involves the formation of a topologically stable soliton, or a single particle with a complex shape. Skyrmions can be found in various materials, such as magnets, superconductors, and even Bose-Einstein condensates. They have many potential applications in data storage, spintronics, and quantum computing. Skyrmions are not easy to visualize, but they can be described mathematically using a topological index, which is a non-zero integer that measures the winding number of the field lines. Skyrmions can have positive or negative winding numbers, and they can move around like tiny particles by sliding from one group of atoms to another. Dr. Singh has taken experience of these materials during his Ph. D. from the University of Tokyo, Japan and Postdoc experiences at University of Nebraska-Lincoln and Boston University with collaboration Lawrence Berkeley National Lab at Berkeley USA and Harvard University at Boston USA and Max Planck Institute for Microstructure Physics Halle (Saale) Germany. Most probably this is first kind of work for India.
Honorable Vice-Chancellor of CUSB Prof. K. N. Singh, Head of Department of Physics Prof. Venkatesh Singh and all the teachers congratulated Ms. Jena on this achievement. The participants from eight countries, USA, Japan, Chile, South Africa, Taiwan, Nepal, Korea and India (IIT Varanasi, IIT Patna, IIT Dhanbad, BHU, University of Allahabad, Indian oil Ltd, Asam Central University, BIT Mesra, DRDO Delhi, IIT Guwahati, NPL Delhi, Pune University etc.) participated in this conference organized at IIT Dhanbad. This research paper was written by Ms. Sanjukta Jena under the guidance of Dr. Vijay Raj Singh at Physics, CUSB Gaya. In this research paper, Ms. Jrna has tried to explain in detail the use of MnSi as a dense memory storage device by using advanced technology. In this conference, out of 300 research papers, only 100 research papers were accepted for presentation in the international conference. The paper was presented by Ms. Jena and evaluated by the jury on several parameters. The advisory committee consisted of professors from various national and international universities.
