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.

Supersymmetric Rényi entropy

, 2013
We consider 3d N≥2 superconformal field theories on a branched covering of a three-sphere. The Rényi entropy of a CFT is given by the partition function on this space, but conical singularities break the supersymmetry preserved in the bulk.

Conditional Randomization Tests for the Specification of Interference Structure

Journal of Applied Econometrics, EarlyView.
ABSTRACT This study proposes specification tests for interference structure in causal inference with spillovers. We focus on experimental settings in which the treatment assignment mechanism is known. To test whether a given exposure mapping adequately summarizes the true interference structure, we develop conditional randomization tests by utilizing ...

On Tight Tree‐Complete Hypergraph Ramsey Numbers

Journal of Graph Theory, EarlyView.
ABSTRACT Chvátal showed that for any tree T $T$ with k $k$ edges, the Ramsey number R ( T , n ) = k ( n − 1 ) + 1 $R(T,n)=k(n-1)+1$. For r = 3 $r=3$ or 4, we show that, if T $T$ is an r $r$‐uniform nontrivial tight tree, then the hypergraph Ramsey number R ( T , n ) = Θ ( n r − 1 ) $R(T,n)={\rm{\Theta }}({n}^{r-1})$.

On the Use of Rényi Entropy for Optimal Window Size Computation in the Short-Time Fourier Transform

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020
In this paper, we investigate the determination of an optimal window length associated with the computation of the short time Fourier transform of multicomponent signals.

Supersymmetric Rényi entropy and charged hyperbolic black holes [PDF]

Journal of High Energy Physics, 2019
The supersymmetric Rényi entropy across a spherical entangling surface in a d-dimensional SCFT with flavor defects is equivalent to a supersymmetric partition function on ℍd−1× 𝕊1, which can be computed exactly using localization.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Logarithmic singularities of Renyi entropy as a sign of chaos?

Journal of High Energy Physics
We propose that the logarithmic singularities of the Renyi entropy of local-operator-excited states for replica index n can be a sign of quantum chaos.

Rényi entropy at large energy density in 2D CFT

Journal of High Energy Physics, 2019
We investigate the Rényi entropy and entanglement entropy of an interval with an arbitrary length in the canonical ensemble, microcanonical ensemble and primary excited states at large energy density in the thermodynamic limit of a two-dimensional large ...
