Entanglement entropy of singular surfaces under relevant deformations in holography
Journal of High Energy Physics, 2018 In the vacuum state of a CFT, the entanglement entropy of singular surfaces contains a logarithmic universal term which is only due to the singularity of the entangling surface.

Physical Review Research, 2021 The ratio between the shear viscosity and the entropy η/s is considered a universal measure of the strength of interactions in quantum systems. This quantity was conjectured to have a universal lower bound (1/4π)ℏ/k_{B}, which indicates a very strongly ...

Applied Mathematics Letters, 2008 The author defines the time scale logarithm and considers some of its properties. \(C_n^1(\mathbb{T},\mathbb{R})\) is a set of nonvanishing continuously delta differentiable functions, \(M_m(C_n^1(\mathbb{T},\mathbb{R}))\) is the set of \(m\times m\) differentiable and invertible matrices with the entries in \(C_n^1(\mathbb{T},\mathbb{R})\).

Quantum-classical eigensolver using multiscale entanglement renormalization
Physical Review Research, 2023 We propose a variational quantum eigensolver (VQE) for the simulation of strongly correlated quantum matter based on a multiscale entanglement renormalization ansatz (MERA) and gradient-based optimization.

Physical Review ResearchRecent advances in boundary critical phenomena have led to the discovery of a new surface universality class in the three-dimensional O(N) model. The newly found “extraordinary-log” phase can be realized on a two-dimensional surface for N3, and on a ...

One and two-dimensional quantum models: quenches and the scaling of irreversible entropy
, 2015 Using the scaling relation of the ground state quantum fidelity, we propose the most generic scaling relations of the irreversible work (the residual energy) of a closed quantum system at absolute zero temperature when one of the parameters of its ...

Evaluation of Three Techniques for Correcting the Spatial Scaling Bias of Leaf Area Index
Remote Sensing, 2018 The correction of spatial scaling bias on the estimate of leaf area index (LAI) retrieved from remotely sensed data is an essential issue in quantitative remote sensing for vegetation monitoring.

Two interacting particles in a random potential
, 2011 We study the scaling of the localization length of two interacting particles in a one-dimensional random lattice with the single particle localization length. We obtain several regimes, among them one interesting weak Fock space disorder regime.

An Antisymmetric Psychometric Function on a Logarithmic Scale
Perception, 2011 This very brief report introduces a psychometric function, very suitable for psychophysical data that displays Weber-like behaviour, because it is antisymmetric on a logarithmic scale.
