Chairing a Session on Quantum Light: When Light Becomes Smarter Reflections on today’s lecture by Dr. Ashok Kumar, IIST Thiruvananthapuram Today, 18 March 2026 , I had the opportunity to chair a very engaging lecture by Dr. Ashok Kumar of IIST Thiruvananthapuram on the topic “Quantum Light for Technology: From Quantum Cryptography to Ultra-Sensitive Sensing.” It was one of those talks that reminds us how modern physics is no longer confined to blackboards alone; it is steadily entering the world of technology. For many people, light is simply something that helps us see. But today’s lecture showed that light can be much more than that. In quantum optics, light can be prepared in very special forms so that it behaves in a more coordinated and useful way than ordinary light. One simple way to imagine this is to think of normal light as a crowd walking in a busy street, each person moving with small random variations. Quan...

National Science Day Talk

  Abstract From Raman to the Future: Women Powering India’s Technological Rise The modern journey of Indian science found its global voice when C. V. Raman discovered the Raman Effect in 1928 - a breakthrough that revealed how light interacts with matter and earned India its first Nobel Prize in science. That discovery was born from simple curiosity - a question as profound as “Why is the sea blue?” From that moment, Indian science began its ascent on the world stage. Nearly a century later, that same spirit of curiosity has evolved - from understanding light scattering to engineering metal–organic frameworks, nanomaterials, and advanced energy systems. The scale has shifted from the visible to the nanoscale, but the ambition remains the same: to explore, innovate, and transform. Today, women scientists across India are at the forefront of this transformation. Leading breakthroughs in nanoscience, battery materials, renewable energy, and sustainable technologies, they repre...

Linear Triatomic Molecule: Modes of Vibration

Image
  Normal Modes of Vibration of a Linear Triatomic Molecule Normal Modes of Vibration of a Linear Triatomic Molecule We consider a linear triatomic molecule consisting of three atoms arranged in a straight line. The two outer atoms have equal mass $m$ , while the central atom has mass $M$ . The atoms are connected by identical springs of force constant $k$ . Let $x_1$, $x_2$, and $x_3$ be the small displacements of the three atoms from their equilibrium positions along the line of the molecule. Assumptions To simplify the analysis, we make the following standard assumptions: The oscillations are small . The restoring forces obey Hooke’s law . The forces are linear functions of displacement. The resulting motion is simple harmonic . Under these assumptions, the problem of molecular vibration reduces to a problem in linear algebra . Kinetic Energy of the System The total kinetic energy of the system is the sum ...

Link to Talk Link to docs I was delighted to be part of the National Seminar on “Functional Materials for Futuristic Innovations (NSFFMI-2026)” organized by the Postgraduate Department of Physics, St. Stephen’s College, Pathanapuram, held on 29–30 January 2026 . It was a pleasure to deliver a lecture as a Resource Person on “Two-Dimensional Nanomaterials: Redefining the Future of Fuel Cell Technology” and to interact with enthusiastic students, researchers, and faculty members. The seminar provided an excellent academic platform for meaningful discussions on emerging materials and their role in future technologies. I sincerely thank Dr. Aswathy P. Pillai , Dr. Rini Varghese , and the entire Department of Physics team for their meticulous planning and warm hospitality. My gratitude also goes to the Principal, Dr. Biju A. , the organizing committee members, and all those who worked behind the scenes to make the event a success. I am happy to have been part of this vibrant academic ga...
