Since the time of its discovery, Alfv茅n wave has been the subject of attention in both theoretical and experimental plasma physics. To date, many different aspects of this wave have been studied using various models. In this study, we adopt linearized Vlasov鈥揗axwell system and investigate ...
a set of plasma processes are triggered including (i) formation of an upward-moving double layer (DL), (ii) setting up of potential gradients in which counterstreaming of electrons occurs on the DL's high-potential side, and (iii) generation of wave packets containing linear and nonlinear w...
In the present numerical study, the unsteady flow physics and the force variation due to the wavy nature of the stationary cylinder is studied in detail. The Reynolds number considered for the study is 100. The geometry of the cylinder is parametrized by the wavelength X, wave amplitude a, ...
Quantum physics: What is really real? A wave of experiments is probing the root of quantum weirdness. Zeeya Merali The 24/7 search for killer quakes Meet the seismologists who work around the clock to pinpoint major earthquakes anywhere on Earth. Alexandra Witze How scientists fool themselves ...
Results of modeling of the coefficients of waveguide mode propagation in a two-layered circular waveguide filled with media having positive and negative refractive indices called Right- and Left-Handed Media (LHM and RHM, respectively) are presented that allow us to conclude that complex waves and ...

Nanophysics Jan 6, 2025 0 88 Plasma heating efficiency in fusion devices boosted by metal screens Heating plasma to the ultra-high temperatures needed for fusion reactions requires more than turning the dial on a thermostat. Scientists consider multiple methods, one of which involves injecting electr...
A striking way to counter such claims on the implausibility of macroscopic quantum coherence would be the successful preparation of quantum superposition states of living objects. A direct route towards such goal is provided by matter–wave interferometers, which have already been instrumental in observi...
