Rényi Entropy of k-Records

Revstat Statistical Journal, 2022
In this paper, we discuss on Rényi entropy of k-records arising from any continuous distribution in detail. The relevance of constructing k-records from random sample in the context of information contained in a random variable has been described in the

Pseudo entropy of primary operators in T T ¯ / J T ¯ $$ T\overline{T}/J\overline{T} $$ -deformed CFTs

Journal of High Energy Physics, 2023
In this work, we investigate the time evolution of the pseudo-(Rényi) entropy after local primary operator quenches in 2D CFTs with T T ¯ / J T ¯ $$ T\overline{T}/J\overline{T} $$ -deformation. Using perturbation theory, we analyze the corrections to the

Minimum Rényi entropy portfolios

, 2021
Accounting for the non-normality of asset returns remains one of the main challenges in portfolio optimization. In this paper, we tackle this problem by assessing the risk of the portfolio through the "amount of randomness" conveyed by its returns.

Stabilizer Rényi Entropy [PDF]

, 2022
International audienceWe introduce a novel measure for the quantum property of “nonstabilizerness”—commonly known as “magic”—by considering the Rényi entropy of the probability distribution associated to a pure quantum state given by the square of the ...

Smooth Rényi Entropy of Ergodic Quantum Information Sources [PDF]

, 2007
We investigate the recently introduced notion of smooth Rényi entropy for the case of ergodic information sources, thereby generalizing previous work which concentrated mainly on i.i.d. information sources.

Rényi Entropy Rate of Stationary Ergodic Processes

, 2023
— In this paper, we examine the Rényi entropy rate of stationary ergodic processes. For a special class of stationary ergodic processes, we prove that the Rényi entropy rate always exists and can be approximated by its defining sequence at most ...

Extending charged holographic Rényi entropy [PDF]

, 2021
Motivated by extended black hole thermodynamics, we generalize the Rényi entropy of charged holographic conformal field theories (CFTs) in d-dimensions.

Quantum, 2023
Bosonic Gaussian states are a special class of quantum states in an infinite dimensional Hilbert space that are relevant to universal continuous-variable quantum computation as well as to near-term quantum sampling tasks such as Gaussian Boson Sampling ...

Excited state Rényi entropy and subsystem distance in two-dimensional non-compact bosonic theory. Part II. Multi-particle states

Journal of High Energy Physics, 2021
We study the excited state Rényi entropy and subsystem Schatten distance in the two-dimensional free massless non-compact bosonic field theory, which is a conformal field theory.
