Site-resolved measurement of the spin-correlation function in the Fermi-Hubbard model [PDF]

open access: yesScience, 2016
Exotic phases of matter can emerge from strong correlations in quantum many-body systems. Quantum gas microscopy affords the opportunity to study these correlations with unprecedented detail.

The full-sky relativistic correlation function and power spectrum of galaxy number counts. Part I: theoretical aspects [PDF]

open access: yes, 2017
We derive an exact expression for the correlation function in redshift shells including all the relativistic contributions. This expression, which does not rely on the distant-observer or flat-sky approximation, is valid at all scales and includes both ...

Multipath Detection and Mitigation of Random Noise Signals Propagated through Naturally Lossy Dispersive Media for Radar Applications

open access: yesSensors, 2023
This paper describes a methodological analysis of the Brillouin precursor formation to understand the impairments undergone by like-noise and random noise waveforms propagating through naturally dispersive media commonly found in radar applications.

Method of estimation of frequency variation relying on estimation of shift of spectral peaks

open access: yesСистемный анализ и прикладная информатика, 2021
Problem of estimation of variated frequency of components of polyharmonic signals has been arose. Three-dimensional time-frequency representation of signals is usually used to resolve this problem.

A marked correlation function for constraining modified gravity models [PDF]

open access: yes, 2016
Future large scale structure surveys will provide increasingly tight constraints on our cosmological model. These surveys will report results on the distance scale and growth rate of perturbations through measurements of Baryon Acoustic Oscillations and ...

Topological phase transition between non-high symmetry critical phases and curvature function renormalization group

open access: yesNew Journal of Physics, 2023
The interplay between topology and criticality has been a recent interest of study in condensed matter physics. A unique topological transition between certain critical phases has been observed as a consequence of the edge modes living at criticalities ...

Methodology for Maintaining the Dynamic Characteristics of Passenger Cars

open access: yesCommunications, 2023
The work presents the results of a statistical analysis of random processes of the coefficient of vertical dynamics of a passenger car variation. To determine the dynamic performance of cars the tests were running on the tracks of JSC "Ukrzaliznytsia ...

SPATIALLY SELECTED SPECKLE-CORRELOMETRY OF TEMPERATURE DEPENDENT GELATION KINETICS [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2017
The paper presents the application of speckle correlometry method with the spatial ring filtration of back scattered field with the usage of localized radiation source for the study of dynamic thermally activated processes in gel-like structures ...
