%0 Journal Article %J Physical Review Letters %D 2012 %T Spontaneous emission by rotating objects: A scattering approach %A Mohammad F. Maghrebi %A Robert L. Jaffe %A Mehran Kardar %X We study the quantum electrodynamics (QED) vacuum in the presence of a body rotating along its axis of symmetry and show that the object spontaneously emits energy if it is lossy. The radiated power is expressed as a general trace formula solely in terms of the scattering matrix, making an explicit connection to the conjecture of Zel'dovich [JETP Lett. 14, 180 (1971)] on rotating objects. We further show that a rotating body drags along nearby objects while making them spin parallel to its own rotation axis. %B Physical Review Letters %V 108 %8 2012/6/7 %G eng %U http://arxiv.org/abs/1202.1485v2 %N 23 %!
