Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Abstract Trans‐ionospheric high frequency (HF: 3–30 MHz) response to atmospheric gravity waves (GWs) is studied in the middle‐latitude ionosphere in relation to thunderstorm activity. SuperDARN HF radar observations are compared against the model simulations to quantify the impact of GW‐generated medium‐scale traveling ionospheric disturbances (MSTID ...

In this work, the reduced spin Hirota–Maxwell–Bloch (rsHMB) equation is examined analytically. This model is useful for characterizing the propagation of femtosecond pulses in an erbium-doped fiber.

Bilinearization and new multi-soliton solutions of mKdV hierarchy with time-dependent coefficients
In this paper, Hirota’s bilinear method is extended to a new modified Kortweg–de Vries (mKdV) hierarchy with time-dependent coefficients. To begin with, we give a bilinear form of the mKdV hierarchy. Based on the bilinear form, we then obtain one-soliton,

Abstract High‐frequency (HF) radio signals rely on ionospheric reflection and refraction to enable long‐range and transcontinental transmission, making them essential for military command, emergency response, and strategic communications. The received field strength is a key parameter for quantifying propagation conditions and optimizing HF circuit ...

On breathers in affine toda theories [PDF]
Oscillating solitonic solutions, the breathers, of affine Toda theory are studied. These breather solutions are constructed from two solitons of the same mass with velocity opposite of each other; by analytically continuing its velocity or rapidity to a ...

Abstract Radiative transfer (RT) models typically solve the radiative transfer equation separately in either the atmosphere or the ocean, limiting accuracy across the atmosphere‐ocean interface. Here, we employ a coupled scalar discrete ordinate RT model to examine methods for the input of measured inherent optical properties (IOPs) of oceanic ...

Many body effects in one-dimensional attractive Bose gases [PDF]
In this thesis we investigate the properties of ultra-cold quantum gases in reduced dimension and the effects of harmonic confinement on soliton-like properties.

Abstract In this study, we investigate the ionospheric and thermospheric responses to the 2018 Mars global dust storm (GDS 2018) by examining atmosphere–ionosphere coupling through tidal structures. Using Mars Atmosphere and Volatile EvolutioN Neutral Gas and Ion Mass Spectrometer observations, we analyze tidal amplitudes, phases, and inter‐species ...

Abstract Mercury's weak intrinsic magnetic field forms a small magnetosphere and thus a bow shock that decelerates the supermagnetosonic solar wind and reflects particles upstream, forming a foreshock in the quasi‐parallel region. This region is populated by backstreaming ions and electrons and associated wave activity.
