Description
In recent years, a considerable amount of literature has suggested that spontaneously
broken quantum field theories can undergo a phase transition to an
unbroken phase due to the effect of Unruh radiation, experienced by uniformly
accelerated observers, at sufficiently high accelerations. However, earlier works
(including one by Unruh himself) and standard renormalization techniques in
curved spacetimes rule out this possibility. In this talk, we will explore the fundamental
reasons behind this discrepancy. The main assumptions and differing
considerations, whether explicitly or implicitly supported by the two distinct
factions, will be discussed. Finally, conclusions will be drawn, aiming to compare
the results obtained for uniformly accelerated systems with those of the
more general gravitational case.
