It has recently been shown that extremely strong electric fields can be created in central collisions of heavy ions, due to which the Schwinger effect significant. A direct analogue field hydrodynamics is acceleration medium. Using parton-hadron-string dynamics (PHSD) framework we model Au-Au at intermediate collision energies $\sqrt{s_{NN}}=4.5-11.5\,$GeV and obtain spatial distribution different time moments. The present study demonstrates high order 1 GeV may generated both non-central collisions, exhibits a core-corona structure. Consequently, contrast case with an field, Unruh expected demonstrated for confined phase temperature less than temperature. Conversely, deconfined phase, relationship inverse. obtained results thus support prediction about existence states $T<T_U$ early stages associated complementary description thermalization terms novel transition
