Pseudo Entropy in U(1) gauge theory

Journal of High Energy Physics, 2022
We study the properties of pseudo entropy, a new generalization of entanglement entropy, in free Maxwell field theory in d = 4 dimension. We prepare excited states by the different components of the field strengths located at different Euclidean times ...

Convexity and robustness of the Rényi entropy

Modern Stochastics: Theory and Applications, 2021
We study convexity properties of the Rényi entropy as function of $\alpha >0$ on finite alphabets. We also describe robustness of the Rényi entropy on finite alphabets, and it turns out that the rate of respective convergence depends on initial alphabet.

On the real-time evolution of pseudo-entropy in 2d CFTs

Journal of High Energy Physics, 2022
In this work, we study the real-time evolution of pseudo-(Rényi) entropy, a generalization of entanglement entropy, in two-dimensional conformal field theories (CFTs).

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

Negative Rényi entropy and brane intersection

Journal of High Energy Physics, 2023
In this work, we revisit the calculation of Rényi entropy in AdS3/(B)CFT2. We find that gravity solutions with brane intersection will lead to negative Rényi entropy.

Page curves and typical entanglement in linear optics [PDF]

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.

Note on entropy dynamics in the Brownian SYK model

Journal of High Energy Physics, 2021
We study the time evolution of Rényi entropy in a system of two coupled Brownian SYK clusters evolving from an initial product state. The Rényi entropy of one cluster grows linearly and then saturates to the coarse grained entropy.
