Spontaneous symmetry breaking induced by curvature : Analysis via non-perturbative 2PI Hartree approximation
Vishal Nath, Kinsuk Roy, Sourav Bhattacharya
In this work we investigate the spontaneous symmetry breaking (SSB) induced by a classical background spacetime's curvature, via the 2 particle irreducible (2PI) non-perturbative e…

Self interacting scalar field theory in general curved spacetimes at zero and finite temperature revisited
Vishal Nath, Sourav Bhattacharya
We revisit the problem of spontaneous symmetry breaking (SSB), its restoration, and phase transition for a self interacting quantum scalar field in a general curved background, at…
