摘要：
我们重新审视狭义相对论中使用的粒子概念。所提出的模型将相对论粒子的能量-动量关系视为准粒子广义能量-动量关系的上分支。这些粒子源于静止大质量粒子的恒定能量与无质量粒子的线性能量-动量关系之间的禁戒交叉。下分支，即被称为“爱因斯坦的地下室”的区域，产生了具有不同运动学的粒子，我们在低速极限下对其进行了分析。允许这些粒子之间存在引力相互作用，我们发现既有吸引也有排斥，这取决于它们相对于绝对空间的速度。这个绝对参考系仅对爱因斯坦的地下室有意义，并且只要不考虑分支之间的耦合，就不影响常规物质的相对论动力学，而弱耦合则会引起局域洛伦兹破坏。最后，我们讨论我们的方法是否可用于模拟暗物质和暗能量的现象。
英文摘要：
We revisit the concept of particles as it is used in special relativity. The presented model treats the energy-momentum relation of relativistic particles as the upper branch of a generalized energy-momentum relation of quasi particles. These particles emerge from a forbidden crossing between the constant energy of a massive particle in rest and the linear energy momentum relation of a massless particle. The lower branch, a regime dubbed as Einstein's basement, gives rise to particles with different kinematics that is analyzed in the low-velocity limit. Allowing for gravitational interaction between those particles we find both attraction and repulsion, depending on their velocity with respect to an absolute space. This absolute frame is only relevant for Einstein's basement and does not affect the relativistic dynamics of regular matter as long as no coupling between the branches is considered, while weak coupling induces local Lorentz violations. We finally discuss whether our approach can be used to model phenomena of dark matter and dark energy.
