Mr. Haridev S. R.

The phenomenon of spontaneous symmetry breaking is one of the cornerstone paradigms of modern physics. In this talk, I shall aim to address the fundamental question - Is this phenomenon observer-dependent? By general covariance, it is clear that a set of inertial observers would perceive the mechanism of spontaneous symmetry breaking as universal. However, the situation is not so straightforward when we consider this phenomenon from the perspective of a uniformly accelerating observer. In this talk, I shall demonstrate that spontaneously broken symmetries can be restored from the viewpoint of an accelerating observer but only above a certain critical value of acceleration, thereby establishing that spontaneous symmetry breaking is indeed an observer-dependent phenomenon. I conclude by commenting on certain applications of our method to the study of symmetry restoration for large N field theories in Rindler and Anti-de Sitter Spacetimes.
