| Description: | [DPS Seminar] Dr. Tanmay Kumar Poddar (Institute for Particle Physics Phenomenology (IPPP) Durham University) -- Searching for ultralight bosons with astrophysical probes and quantum sensors |
| Date: | Wednesday, Jul 29, 2026 |
| Time: | 2:30 p.m. - 4 p.m. |
| Venue: | Asima Chatterjee Lecture Theatre |
| Details: | Ultralight bosons are well-motivated candidates for physics beyond the Standard Model and may couple feebly to photons and fermions. In this talk, I will discuss how Crab pulsar polarisation can constrain ultralight axions through their distinct astrophysical signatures. I will then explore complementary laboratory probes based on quantum interferometry, including axion-induced Aharonov-Bohm phases in rf-SQUIDs and Berry phases in Mach-Zehnder interferometers. These geometric and topological effects provide promising routes to search for ultralight bosons and their weak interactions with Standard Model particles. |
