arXiv:2404.11632v1 Announce Type: new
Abstract: We show that the Raychaudhuri equation remains invariant for certain solutions of scalar fields $phi$ whose Lagrangian is non-canonical and of the form $mathcal{L}(X,phi)=-V(phi)F(X)$, with $X=frac{1}{2} g_{munu} nabla^{mu}phi nabla^{nu} phi$, $V(phi)$ the potential. Solutions exist for both homogeneous and inhomogeneous fields and are reminiscent of inflaton scenarios.

Raychaudhuri Equation and Solutions for Non-Canonical Scalar Fields

In a recent study, it has been demonstrated that the Raychaudhuri equation remains invariant for certain solutions of scalar fields that have a non-canonical Lagrangian. These solutions are described by the Lagrangian $mathcal{L}(X,phi)=-V(phi)F(X)$, where $X=frac{1}{2} g_{munu} nabla^{mu}phi nabla^{nu} phi$ and $V(phi)$ is the potential function. These solutions have properties similar to inflaton scenarios and can be found in both homogeneous and inhomogeneous fields.
