Motivated by the idea of entanglement loss along renormalization group flows, analytical majorization relations are proven for the ground state of $(1+1)$-dimensional conformal field theories. For any of these theories, majorization is proven to hold in the spectrum of the reduced density matrices in a bipartite system when changing the …
