A pathbreaking research by IITKgp Faculty has opened up possibilities for the development of quantum devices. Prof. Sajal Dhara who joined the Department of Physics at IIT Kharagpur in 2016, has discovered negative mass particles of polaritons which are composed of half-light and half-matter.Prof. Dhara and his collaborators at the University of Rochester and ICTS, Bangalore have discovered new insights on the mass of such intriguing particles. The new understanding is expected to inspire a giant leap towards futuristic technology development.
The research has been featured in the esteemed ‘Nature Physics’ journal in their October 2017 issue. The collaborators involved in this work are Dr. C. Chakraborty, Dr. K. M. Goodfellow, Dr. L. Qiu, Dr. T. A. O’Loughlin, Prof. G. W. Wicks, and Prof. A. N. Vamivakas, all from the University of Rochester and Prof. Subhro Bhattacharjee from ICTS, TIFR.
