论文摘要
在本文中，我们提出了一种新的理论情况，其中动态迪拉克费米子和爱因斯坦的重力都具有正宇宙的正常和扭转，并在拓扑阶段通过自发对称性破裂出现。该阶段不包含任何局部传播的自由度，并由公制的非代数仪表理论描述，该理论在De Sitter组下是不变的。通过动态的希格斯机制将这组分解为Lorentz子组后，我们表明费米子变得动态和庞大，而局部lorentz-invariant时空的动力学可以通过纺纱球场的凝结来诱导。在我们的理论中，狄拉克质量和牛顿的引力常数都通过众所周知的物理机制自然出现。
In this paper, we present a new theoretical scenario in which both dynamical Dirac fermions and Einstein's gravity with a positive cosmological constant and torsion emerge via a spontaneous symmetry breaking in a topological phase. This phase does not contain any local propagating degrees of freedom and is described by a metric-independent fermionic gauge theory, which is invariant under the de Sitter group. After breaking this group to its Lorentz subgroup through a dynamical Higgs mechanism, we show that fermions become dynamical and massive while the dynamics of the locally Lorentz-invariant spacetime can be induced via the condensation of the spinor field. Within our theory, both the Dirac mass and the Newton's constant of gravitation naturally emerge through well-known physical mechanisms.
