The origin of scale-scale correlations of the density perturbations during inflation [PDF]

open access: yes, 1999
We show that scale-scale correlations are a generic feature of slow-roll inflation theories. These correlations result from the long-time tails characteristic of the time dependent correlations because the long wavelength density perturbation modes are ...

Slowdown of photoexcited spin dynamics in the non-collinear spin-ordered phases in skyrmion host GaV4S8

open access: yesNature Communications, 2022
Skyrmions are a topological magnetic texture that have garnered considerable interest for various technological applications. Here, Sekiguchi et al. investigate the ultrafast optical response of GaV4S6, and find a significant reduction in the thermal ...

Correlations in superstatistical systems [PDF]

open access: yes, 2007
We review some of the properties of higher-dimensional superstatistical stochastic models. As an example, we analyse the stochastic properties of a superstatistical model of 3-dimensional Lagrangian turbulence, and compare with experimental data ...

Disorder induced stripes in d-wave superconductors

open access: yesNew Journal of Physics, 2013
Stripe phases are observed experimentally in several copper-based high- T _c superconductors near 1/8 hole doping. However, the specific characteristics may vary depending on the degree of dopant disorder and the presence or absence of a low-temperature ...

Single Crystal Growth and Anisotropic Magnetic Properties of Li2Sr[Li1 − xFexN]2

open access: yesInorganics, 2016
Up to now, investigation of physical properties of ternary and higher nitridometalates has been severely hampered by challenges concerning phase purity and crystal size. Employing a modified lithium flux technique, we are now able to prepare sufficiently

Benzothiadiazole-based rotation and possible antipolar order in carboxylate-based metal-organic frameworks

open access: yesCommunications Chemistry, 2023
By modifying organic ligands of metal-organic framework with dipolar units, they turn suitable for various applications, e.g., in the field of sensor systems or switching of gas permeation.

Experimental fully contextual correlations [PDF]

open access: yes, 2012
Quantum correlations are contextual yet, in general, nothing prevents the existence of even more contextual correlations. We identify and test a noncontextuality inequality in which the quantum violation cannot be improved by any hypothetical postquantum

Spin-Orbit Correlations

open access: yes, 2008
We summarize the intuitive connection between deformations of parton distributions in impact parameter space and single-spin asymmetries. Lattice results for the $x^2$-moment of the twist-3 polarized parton distribution $g_2(x)$ are used to estimate the ...
