The definition of entropy for quantum unstable systems: a view-point based on the properties of Gamow states

Continuing this line of thought, in this paper we have obtained the entanglement entropy for the half-space of a free scalar the- ory in a Gaussian cMERA tensor network as a function

For the second point, after introducing and characterizing in several ways the notion of conditional relative entropy, we prove different results of quasi-factorization of the

Relative correlation energy as a function of the overall entropy for the exact ground state of the three-level Lipkin model.. overall entropy increases, reflecting the fact

Therefore we applied the K2V method to calculate mean potential energy maps for every residue conditioned to the folding state of its nearest neighbor residues what provides

If (X, d) is a compact metric space then there is a useful equivalent definition of topological sequence entropy, also introduced by Goodman in [6]. Z°°) will denote the set of

We have studied the relaxation process of the specific heat and the entropy for the three-dimensional Coulomb glass at very low temperatures and in thermal equilibrium9. The long
