| Summary: | We investigate the entanglement structure of a bipartite quantum system through the lens of quantum thermodynamics in the absence of conformal symmetry. Specifically, we consider the long-range Kitaev model, where the pairing interaction decays as a power law with exponent α , with broken conformal symmetry for $\alpha\,\lt\,3/2$ . We analytically show that the bound energy, a quantum thermodynamical quantity, is linearly proportional to the square of entanglement entropy per unit system size for α = 1 where conformal symmetry is broken. We further show that for all values of α , bound energy, in the thermodynamic limit, shows a pronounced minimum at the critical point, which enables the identification of µ = 1.
