  In this paper we apply the formalism of Accelerated Quantum Dynamics (AQD) to
the radiative stopping of highly relativistic electrons in ice. We compute the
acceleration profile of the electron along with its lifetime to decay into a
muon. The Planckian spectrum of the emitted muon along with the its generalized
displacement law are presented and used to quantify the muons properties. The
results predict the acceleration-induced decay of electrons at IceCube
energies. The signal of electron decay at IceCube manifests itself as an excess
of track topologies in an energy window accessible experimentally. This setting
has the potential to probe the Unruh effect as well investigate the flavor
content of cosmic ray neutrinos.
