Summary: The basic properties of (3+1)-dimensional cylindrical dust ion-acoustic solitary waves in a multi-component plasma medium consisting of inertial ions, Maxwellian electrons, and stationary negative dust particles have been studied. The impacts of nonplanar geometry and presence of static negative dust particles on the dust ion-acoustic solitary structures have been investigated.

Summary: This study systematically investigates the propagation of both linear and nonlinear dust acoustic waves in a collisional magnetized warm dusty plasma. The analysis reveals that the linear damping is caused by dust-neutral collisions and the nonlinear excitations are significantly influenced by various plasma parameters.

Summary: In this paper, the non-linear propagation of dust ion-acoustic waves in a complex dusty plasma is fully analyzed using bifurcation techniques and numerical simulations. A dynamical system capturing the main features of traveling wave solutions and transition between nonlinear modes is derived. The study reveals the existence domains of stability regions for different ranges of electron nonextensivity and dust concentration. The motion dynamics of low-frequency dust ion-acoustic traveling waves undergoes a transcritical bifurcation at critical points of nonextensivity parameter and dust concentration, resulting in a switch of stability. A new kind of solitary structure characterized by transcritical bifurcation parameters with half-stable equilibrium points is observed. The effects of nonextensive parameter and dust polarity on the transition between nonlinear traveling waves are investigated.

Summary: The dynamics of a fully nonlinear structure of a six-component dusty cometary plasma system were investigated using Sagdeev pseudo-potential techniques. Nonlinear waves, as well as localized negative and positive amplitude electrostatic pulses, can exist and propagate in the plasma system. The impact of intrinsic plasma parameters on the features of solitary wave electrostatic potential profile and associated electrostatic field were extensively studied.

Summary: In this study, Dust-acoustic waves (DAWs) are investigated in an electrostatic self-gravitating dusty plasma. The electrons and ions are modeled using a nonextensive q-distribution function, while the dust particles follow a Maxwellian distribution. The plasma dispersion relation and instability growth rate are derived using a Vlasov-Poisson set of equations. The effects of various parameters, such as self-gravitation, nonextensivity, dust concentration, and streaming speed, on the wave frequency and growth rate are examined. The applicability of the results in interstellar dust clouds is also discussed.

Summary: This study investigates the nonlinear features of dust-acoustic waves in a multicomponent, collisional, magnetized dusty plasma. The DZK equation is solved using the generalized (G' / G)-expansion method and the Painleve analysis method, providing a class of solutions for different types of nonlinear waves. The effects of various plasma parameters on the behavior of the waves are also examined, with relevance to the understanding of cosmic dust-laden plasmas.

Summary: Pinned solitons, a special class of nonlinear solutions moving with supersonic objects in fluids, have been experimentally observed for the first time in a dusty plasma flowing over a charged obstacle. These solitons change in nature from single-humped to multi-humped structures as the flow velocity of the dust fluid increases, demonstrating a systematic study of their propagation characteristics. Qualitative comparisons with numerical solutions of the forced Korteweg de Vries equation were made to further understand these experimental findings.

Summary: Dusty plasmas are common in the universe and have various applications, but the theoretical understanding of the interaction between dust grains and their environment is still incomplete. Experimental measurements presented by the authors challenge the widely used collisionless electron assumptions in current models of dusty plasmas. The findings suggest that the electron current may not be collisionless in certain plasma conditions, which could require corrections to existing theories.

Summary: Motivated by the expanding interest in complex plasmas, this article discusses the equivalent photon charge in dusty electron-ion plasmas. The dusty plasma response, in terms of the electron density perturbation driven by electromagnetic waves, is investigated. The resulting polarization of the plasma medium caused by the photon ponderomotive force of the electromagnetic radiation pressure gives rise to an effective photon electric charge. The acquired photon charge is determined based on the characteristic parameters, with a strong dependence on the free electron density and the photon frequency. This photonic charge is relevant for studying the photon-plasma couplings in most plasma mediums, especially those in the early Universe.

Summary: In this study, we investigated the dynamics of quasiparticles and collective excitations in the material ZrTe5 using ultrafast optical pump-probe spectroscopy. Our results revealed two coherent oscillations with extremely low energies, which softened as the temperature approached two different critical temperatures. These oscillations were attributed to the amplitude mode of photoinduced dynamic charge density waves in ZrTe5. Additionally, we observed a peculiar quasiparticle decay process associated with a specific mode below a transition temperature. These findings provide important information for studying fluctuating order parameters and quasiparticle dynamics in different low-dimensional topological systems and materials.

Summary: A hydrodynamic model is used to study the linear and nonlinear characteristics of collisional dust acoustic waves in degenerate inertialess ions and electrons. The dispersion properties of the waves are derived, with inertia provided by dust particles and restoring force from electrons and ions. Nonlinear analysis is conducted using the reductive perturbation technique to derive the dissipative nonlinear Schroeurodinger equation. The modulated growth rate of instability, envelope, and rogue waves are investigated both numerically and analytically. This paper contributes to understanding the linear and nonlinear properties of electrostatic excitations in degenerate dusty plasma, which are relevant to DUSTY DAZ WDs.

Summary: This study investigates the effects of magnetic field, plasma rotation, and different parameters on the nonlinear characteristics of dust-ion-acoustic solitary waves. The research derives the nonlinear modified Zakharov-Kuznetsov equation and analyzes wave solutions in magnetorotating plasma. The results show that magnetic field, Coriolis force, and plasma constituents play significant roles in changing the amplitude and width of the solitary waves.

Summary: A theoretical investigation was conducted to study the propagation of dust-acoustic solitary waves in a dusty plasma system. The study considered dynamic positively and negatively charged warm dust species, as well as nonthermally distributed ion and electron species. The research derived the cylindrical Kadomstev-Petviashvili equation using the reductive perturbation method, which showed the existence of solitary wave solutions. The effects of various parameters on the properties of the solitary waves were investigated, and their relevance to cometary tails, upper mesosphere, and Jupiter's magnetosphere was briefly discussed.
