Renyi entropies for classical string-net models [PDF]

open access: yesPhysical Review B, 2014
In quantum mechanics, stringnet condensed states - a family of prototypical states exhibiting non-trivial topological order - can be classified via their long-range entanglement properties, in particular topological corrections to the prevalent area law of the entanglement entropy.

On Cumulative Residual Renyi's Entropy

open access: yesRevista Colombiana de Estadística, 2022
At the entropy measures and their generalization path, in the direction of statistics and information science, recently, Sunoj & Linu (2012) proposed the cumulative residual Renyi's entropy  of order α and its dynamic version and studied its main properties.

Renyi entropy of the interacting Fermi liquid [PDF]

open access: yesPhysical Review B, 2013
We perform quantum Monte Carlo calculations to determine how the Renyi entropies, $S_n$, of the interacting Fermi liquid depend on Renyi order, $n$, and scale as a function of system size, $L$. Using the swap operator and an accurate Slater-Jastrow wave function, we compute Renyi entropies for spinless fermions interacting via the Coulomb and modified ...

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

open access: yesJournal 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

Supersymmetric Renyi Entropy in $CFT_2$ and $AdS_3$ [PDF]

open access: yes, 2015
We show that in any two dimensional conformal field theory with (2, 2) supersymmetry one can define a supersymmetric analog of the usual Renyi entropy of a spatial region A.

A limit of the quantum Renyi divergence [PDF]

open access: yes, 2013
Recently, an interesting quantity called the quantum Renyi divergence (or "sandwiched" Renyi relative entropy) was defined for pairs of positive semi-definite operators $\rho$ and $\sigma$. It depends on a parameter $\alpha$ and acts as a parent quantity

Sphere Rényi entropies [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2013
I give some scalar field theory calculations on a d-dimensional lune of arbitrary angle, evaluating, numerically, the effective action which is expressed as a simple quadrature, for conformal coupling. Using this, the entanglement and Renyi entropies are computed. Massive fields are also considered and a renormalisation to make the (one-loop) effective

Page curves and typical entanglement in linear optics [PDF]

open access: yesQuantum, 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 ...

On Variational Expressions for Quantum Relative Entropies [PDF]

open access: yes, 2017
Distance measures between quantum states like the trace distance and the fidelity can naturally be defined by optimizing a classical distance measure over all measurement statistics that can be obtained from the respective quantum states.
