Title- A brief introduction to solitons and some of its applications

Date & Time: Thursday, 08th February at 4.00 p.m. 

Venue: Rajarshi Bhattacharya Memorial Lecture Hall, Chemical Sciences Building


Soliton is a counter-intuitive wave entity arising from a delicate balance between dispersion and nonlinearity. Interestingly, solitons, solitary waves that maintain their shape and coherence while propagating through nonlinear media, have captivated scientists and engineers for decades with their remarkable properties. From their discovery in water waves to their manifestations in diverse physical systems such as optics, plasmas, tsunami dynamics, condensed matter, magnetism, particle physics, solitons gives rise to a wide number of exciting phenomena. In my talk, through engaging visuals and accessible explanations, I will unravel the mysteries of solitons exploring their fundamental characteristics and theoretical underpinnings, shedding light on their stability mechanisms, interactions, and potential applications.
