ONLINE talk on 12th June 11AM: DEEPTHI GODABA VENKATA
Dear all
Hope you are all doing well during the summer.
This is to let you know that our PhD candidate Deepthi, a recipient of the International Travel Award (ITA) from the institute, will give a talk on Thursday (12th June) from 11AM to 12PM IST. Since most people are away, the talk will be in online mode. Please find the relevant details below.
Hope to see you all in the talk.
Cheers
Aritra

Title- Pulse Modulation due to Superfluid transition in Neutron Star
Abstract-
Matter with extreme baryon density is believed to occur in the core of a neutron star, allowing for various novel phases, from a conventional nucleon superfluid phase to exotic high-baryon-density QCD phases. Here, we point out a unique phenomenon associated with phase transitions to a superfluid phase, which may be the nucleon superfluid phase or a phase like the CFL phase, allowing for superfluid vortices. A random network of vortices forms via the Kibble-Zurek mechanism in any superfluid phase transition. The angular momentum carried by the random superfluid vortex network has to be balanced by an equal and opposite angular momentum in the normal fluid due to the conservation of angular momentum, thereby imparting an arbitrarily oriented angular momentum component to the outer shell in the case of a neutron star. This will induce a wobbling of the neutron star and affect its spin, which can be detected for pulsars with high-precision measurements of the pulse timings and the pulse profile changes.
