Lattice simulations in Rindler spacetime show that acceleration turns the confinement-deconfinement transition in gluodynamics into a spatial crossover that approximately follows the Tolman-Ehrenfest law, while the critical temperature stays unchanged.

abstract
In this work we consider the spontaneous symmetry breaking of the electroweak $SU(2)_L\times U(1)_Y$ gauge group into $U(1)_{em}$ taken place in the Standard Model of particle physics as seen from the point of view of an accelerating observer. According to the Unruh effect that observer detects the Minkowski vacuum as a thermal bath at a temperature proportional to the proper acceleration $a$. Then we show that (in a certain large $N$ limit) when the acceleration is bigger than the critical value $a_c = 4 \pi v$ (where $v$ is the Higgs vacuum expectation value), the electroweak $SU(2)_L\times U(1)_Y$ gauge symmetry is restored and all elementary particles become massless. In addition, even observers with $a<a_c$, can see this symmetry restoration in the region close to the Rindler horizon.

Spatial confinement-deconfinement transition in accelerated gluodynamics within lattice simulation
Lattice simulations in Rindler spacetime show that acceleration turns the confinement-deconfinement transition in gluodynamics into a spatial crossover that approximately follows the Tolman-Ehrenfest law, while the critical temperature stays unchanged.
