[Astro] [CAPT] Particle Cosmology and Gravity Seminar on 21st January: Ramkishor Sharma (Prague)

[Swagat Mishra]

Dear All,

                   Wish you a happy new year. We will begin our Particle Cosmology and Gravity seminars from next week. (Elisa will be slowly taking over the organising responsibilities from me from this term). I will send a list of upcoming seminar speakers until the end of February by early next week.

  1.
Speaker: Ramkishor Sharma  (Prague Institute of Physics)  (Online Seminar)



            Seminar date: 21st January, Tuesday, 1 pm UK time



            Venue: Seminar Room A 113



             Title:  Generation of Magnetic Fields during Inflation



Abstract: Magnetic fields have been observed in galaxies, galaxy clusters, and even in the

intergalactic medium. While astrophysical mechanisms can account for the magnetic fields
in galaxies and galaxy clusters, they may not fully explain the presence of magnetic fields in
the intergalactic medium. In this talk, I will discuss the generation of these large-scale magnetic
fields in the early universe, potentially arising during the inflationary era. I will present my work,
which addresses the challenges associated with generating these fields during inflation.
Furthermore, I will discuss our recent work exploring the possibility of magnetic field generation
In the Spectator Chromo-Natural Inflation (SCNI) model. In this model, inflationary magnetogenesis
is realized by identifying the non-Abelian sector of SCNI with the SU(2)_L sector of the Standard Model,
providing a novel mechanism for the emergence of primordial magnetic fields during inflation.
