We present a universal relation between the flow of a Renyi entropy and the full counting statistics of energy transfers. We prove the exact relation for a flow to a system in thermal equilibrium that is weakly coupled to an arbitrary time-dependent and nonequilibrium system. The exact correspondence, given by this relation, provides a simple protocol to quantify the flows of Shannon and Renyi entropies from the measurements of energy transfer statistics.

Strong correlations between the exponent α and the particle number for a Renyi monoatomic gas in Gibbs' statistical mechanics.
It is shown that already at the classical level there is a strong correlation between Renyi's exponent α and the number of particles for very simple systems.
Troublesome aspects of the Renyi-MaxEnt treatment.
A hidden relation is uncovered in Renyi's variational problem (MaxEnt) that connects the two associated Lagrange multipliers with the mean energy 〈U〉 and the Renyi parameter α and produces anomalous Renyi-MaxEnt thermodynamic results.
Optimum capacity and full counting statistics of information content and heat quantity in the steady state
The performance of communication through a quantum conductor is limited by the laws of physics. The optimum channel capacity, the maximum rate at which information can be transmitted under a given
Fluctuation of information content and the optimum capacity for bosonic transport
The Renyi entanglement entropy of order zero is the partition function, which exponentially depends on the optimum capacity, and the water-filling theorem is recovered in the wave-like regime.

Full counting statistics of information content and particle number
This work considers a bipartite quantum conductor and discusses the joint probability distribution of particle number in a subsystem and the self-information associated with the reduced density matrix of the subsystem, and calculates the Renyi entropy of a positive integer order subjected to the particle number constraint.
