A bstract In this work we provide a method to study the entanglement entropy for non-Gaussian states that minimize energy functional of interacting quantum field theories at arbitrary coupling. To end, build class variational trial wavefunctionals with help exact nonlinear canonical transformations. The calculability bonanza shown by these ansatze allows us compute using prescription ground sta...

Traditionally, the Method of (Shannon-Kullback’s) Relative Entropy Maximization (REM) is considered with linear moment constraints. In this work, the method is studied under frequency moment constraints which are non-linear in probabilities. The constraints challenge some justifications of REM since a) axiomatic systems are developed for classical linear moment constraints, b) the feasible set ...

A generally relativistic theory of thermodynamics is developed, based on four main physical principles: heat is a local form of energy, therefore described by a thermal energy tensor; conservation of heat, or the local first law, equivalent to conservation of mass; entropy is a local current; and non-destruction of entropy, or the local second law. A fluid is defined by the thermostatic energy ...
