Spontaneous Breaking of (2+1)-dimensional Lorentz Symmetry by an antisymmetric tensor

Jia-Hui Huang, Guang-Zhou Guo, Hao-Yu Xie +2

One kind of spontaneous (2+1)-dimensional Lorentz symmetry breaking is discussed. The symmetry breaking pattern is $SO(2,1)\to SO(1,1)$. Using the coset construction formal…
