物理色散关系的几何

Geometry of physical dispersion relations

Dennis Raetzel, Sergio Rivera, Frederic P. Schuller

摘要:

作为色散关系,余切丛函数必须满足三个简单的代数性质。这些条件是从具有预测性物质场动力学和正能量的独立概念的不可避免的物理要求中得出的。因此,标准相对论色散关系的可能修改受到严格限制。例如,与Gambini-Pullin或Myers-Pospelov的麦克斯韦理论的流行变形相关的色散关系是不可接受的。

英文摘要:

To serve as a dispersion relation, a cotangent bundle function must satisfy three simple algebraic properties. These conditions are derived from the inescapable physical requirements to have predictive matter field dynamics and an observer-independent notion of positive energy. Possible modifications of the standard relativistic dispersion relation are thereby severely restricted. For instance, the dispersion relations associated with popular deformations of Maxwell theory by Gambini-Pullin or Myers-Pospelov are not admissible.
