WebIntroduction to Bimetric Theory We begin this chapter by recalling some ideas from General Relativity(GR). We then introduce a linear theory of massive gravity, the Fierz-Pauli theory and explain issues faced by it and similar theories before introducing the ghost free bimetric theory which was rst introduced by Hassan and Rosen in 2011 [1] [2]. WebThis e ective theory is geometric in nature, covariant with respect to spatial dif-feomorphisms, and nonlinear by construction. Similarly to Ref. [26], the theory consists of a Chern-Simons TQFT interacting with a massive spin-2 eld, whose dynamics is governed by an action reminiscent of the action for bimetric theory of massive gravity. discord fishing planet frWebNov 10, 2024 · We present a bimetric low-energy effective theory of fractional quantum Hall (FQH) states that describes the topological properties and a gapped collective excitation, known as the Girvin-Macdonald-Platzman (GMP) mode. The theory consists of a topological Chern-Simons action, coupled to a symmetric rank-2 tensor, and an action à … discord fishington.io
