Explore the effects of electric and magnetic fields, including temperature, on a scalar self-interacting theory λφ⁴ in this 39-minute conference talk by Marcelo Loewe from Pontificia Universidad Católica (PUC), Chile. Delivered as part of the Workshop on Electromagnetic Effects in Strongly Interacting Matter at ICTP-SAIFR in October 2022, delve into the intricate interplay between electromagnetic fields and strongly interacting matter. Gain insights into the behavior of scalar fields under various conditions and understand the implications for theoretical physics and related fields.
