2025-02-05 15:00 - 17:00 (Asia/Kolkata) | C-602, C V Raman Block
The Department of Physics is organising a Departmental Research Seminar on “Nuclear Processes during the Big Bang Nucleosynthesis” on February 05, 2025. The seminar will be delivered by renowned academician Dr Martin Schaefer, Department of Theoretical Physics, Nuclear Physics Institute, Czech Academy of Sciences.
Tune in to hear from the expert on the phenomenon of Big Bang Nucleosynthesis.
Abstract
It is believed that at the early stage of the Universe, roughly 10 seconds after the Big Bang, the temperature dropped sufficiently to allow the first atomic nuclei to form. Subsequent nuclear reactions produced stable helium and lithium isotopes and negligible traces of heavier elements. This process is known as the primordial nucleosynthesis of light elements or Big Bang Nucleosynthesis (BBN). At the end of BBN, the specific primordial abundances left an observable imprint in the current Universe. This echo nowadays serves to test the Hot Big Bang theory and the Standard Model of particle physics. An accurate description of BBN nuclear reactions is crucial in studying primordial nucleosynthesis. Nowadays, reaction dynamics can be calculated by applying highly sophisticated ab initio theoretical methods. In my contribution, I will discuss how a systematic approach to describing nuclear interactions and ab initio methods might contribute to revealing mysteries about this early stage of the Universe.

Research Seminar on Macroscopic Quantum Tunneling
2025-10-30 15:00 - 16:00 | S-607, SR Block
The Department of Physics is organising a Research Seminar on “Macroscopic Quantum Tunneling and Nobel Prize in Physics – 2025” by Dr Krishna Prasad Maity, Assistant Professor, Department of Physics, SRM University-AP.
Abstract
Quantum tunneling, proposed by Erwin Schrödinger in 1926, is a unique quantum phenomenon with no classical equivalent. It has been observed in microscopic systems like alpha decay and scanning tunneling microscopy but remained unverified at the macroscopic scale for decades.
This year’s Nobel Prize in Physics was awarded to John Clarke, Michel H Devoret, and John M Martinis from the University of California for observing macroscopic quantum tunneling in a superconducting tunnel junction, known as the Josephson junction. Their experiments measured the voltage across the junction, corresponding to the quantum phase difference between two superconductors, and revealed that the particles occupy discrete, quantized energy levels. This pioneering work laid the foundation for qubits—the basic units of future quantum computers. In this talk, I will discuss their discovery and its significance for the future of quantum technology.

Fracmeet 2025
2025-11-22 09:30 - 2025-11-24 17:00 | Tiered Classroom, 5th Floor, Admin Block
The Department of Physics is organising FRACMEET-2025: Collective Phenomena in Disordered Systems- II, a three-day interdisciplinary conference from November 20-22, 2025, at the Tiered Classroom, Level 5, Homi J Bhabha Block.
The focus of this three-day conference is to discuss the recent developments and future challenges in the multiphase flow, dynamics of fracture, recent problems in soft matter from a point of view of statistical mechanics and non-linear physics.
Fracmeet will host researchers, from theory and experiments, from diverse fields to discuss the recent developments and future challenges in the upscaling process, and in particular the role of statistical and non-linear physics.
