    "abstract": "There have been several experiments which hint at evidence for superluminal\ntransport of electromagnetic energy through a material slab. On the theoretical\nside, it has appeared evident that acausal signals are indeed possible in\nquantum electrodynamics. However, it is unlikely that superluminal signals can\nbe understood on the basis of a purely classical electrodynamic signals passing\nthrough a material. The classical and quantum theories represent quite\ndifferent views, and it is the quantum view which may lead to violations of\nEinstein causality.",
