旋转物体的自发发射:散射方法

Spontaneous emission by rotating objects: A scattering approach

Mohammad F. Maghrebi, Robert L. Jaffe, Mehran Kardar

摘要:

我们研究了量子电动力学(QED)真空中存在的一个机构沿其对称轴旋转,并表明,该对象自发地发射能量,如果它是有损耗的。辐射功率仅根据散射矩阵表示为一般迹公式,与Zel 'dovich [JETP Lett. 14,180(1971)]关于旋转物体。我们进一步表明,一个旋转的身体拖动附近的物体,同时使他们旋转平行于自己的旋转轴。

英文摘要:

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.
