Three important classes of nonlinear phenomena, namely solitons, shocks and vortices in dusty plasmas, have been discussed. The static and mobile charged dust grains have been considered in order to study all of these nonlinear phenomena. The effects of nonplanar geometry, dust grain charge fluctuat...

In recent days, study of topological Weyl semimetals have become an active branch of physics and materials science because they led to realization of the Weyl fermions and exhibited protected Fermi arc surface states. Therefore, topological Weyl semimetals TaX (X = P, As) are important electronic sy...

Abstract Structural colors widespread in nature have been theoretically in‐depth studied and manufactured through the artificial approaches such as self‐assembly and nanolithography thanks to the rapidly developing nanotechnology. Structural colors based on elastomers and hydrogels can be readily mo...

The topological Weyl semimetal CaSn3, belonging to the AuCu3 type cubic structure, is an important electronic system to investigate both from the point of view of fundamental physics and prospective applications. In this work, we have studied the structural, elastic, mechanical, electronic, bonding,...

Effects of ion temperature on compressive and rarefactive ion-acoustic solitary waves, which have been found to coexist in non-thermal plasmas, are investigated by the pseudopotential approach, which is valid for arbitrary amplitude solitary waves. It is shown that the effects of ion temperature cha...

Recent observations reveal that plasmas in cometary tails contain charged dust grains of positive and negative polarities. Our objective here is to show that such a two‐component dusty plasma supports dust‐Langmuir and dust‐acoustic waves. The latter in the nonlinear regime propagate in the form of ...

The nonlinear propagation of the dust ion-acoustic waves has been investigated accounting for the charge fluctuation dynamics of stationary dust grains in an unmagnetized dusty plasma. The Korteweg-de Vries equation, as well as the Korteweg-de Vries-Burgers equation, are derived by employing the red...

This paper presents a simple yet accurate method for solving the Schrödinger equation to calculate the quantum mechanical transmission probability across arbitrary potential barriers. It is based on the concept of wave impedance analogous to transmission line theory. The quantum mechanical transmiss...

Abstract Multiresponsive elastic poly(methyl methacrylate‐butyl acrylate) (P(MMA‐BA)) copolymer nanoparticles with controlled sizes are fabricated through a one‐step method, which further serve as building blocks for the construction of multiresponsive films via self‐assembly. Taking advantage of th...

Separating substances by their chirality faces great challenges as well as opportunities in chemistry and biology. In this study, we propose an all-optical solution for passive sorting of chiral objects using chirality-dependent lateral optical forces induced by judiciously interfered fields. First,...
