Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

In a study published in Physical Review Letters, scientists at GSI Helmholtzzentrum für Schwerionenforschung have discovered ...

Correlation coefficients can mean a positive, negative, or no relationship between two variables. Use correlation coefficients to help pick securities for your portfolio.

At the heart of these studies lies the Einstein relation, where the mean squared displacement of particles enables the estimation of self-diffusion coefficients.

IT is well known that under vacua of less than 1 torr the coefficient of friction of graphite on itself and other materials increases from its usual value of about 0.15 to a value of 0.5, or even ...

Orbital Angular Momentum Waves: Generation, Detection, and Emerging Applications Abstract: Orbital angular momentum (OAM) has aroused a widespread interest in many fields, especially in ...

Inspired by the unique and compelling traits of orbital angular momentum (OAM) laser beams, such as the twisted wavefront and annular-shaped intensity pattern, we use this work to design antennas ...

Recent findings confirm the conservation of orbital angular momentum in single-photon interactions, reinforcing fundamental ...

A dual-mode (l=-1 and 3) orbital angular momentum (OAM) antenna array is described in this paper. Gene Algorithm (GA) method is used to optimize the excitation of antenna array for separating ...

A novel multichannel free-space optical (FSO) communication system based on orbital angular momentum (OAM) carried by frozen waves with different longitudinal patterns is studied in this paper. The ...

Due to the broadcast and open characteristics of wireless channels, near-field physical layer security has attracted much attention to facilitate wireless information security against illegitimate ...
