@article {1528, title = {Spontaneous emission by rotating objects: A scattering approach}, journal = {Physical Review Letters}, volume = {108}, year = {2012}, month = {2012/6/7}, abstract = { 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{\textquoteright}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. }, doi = {10.1103/PhysRevLett.108.230403}, url = {http://arxiv.org/abs/1202.1485v2}, author = {Mohammad F.
