Accurate theoretical description of these systems is challenging both, conceptionally and with respect to computational resources. While for classical systems, in principle, exact simulations are possible via molecular dynamics, this is not the case for quantum systems. Alternatively, one can use many-particle approaches such as hydrodynamics, kinetic theory, or nonequilibrium Green functions (NEGF). However, NEGF exhibit a very unfavorable cubic scaling of the CPU time with the number of time steps. An alternative is the G1–G2 scheme [N. Schlünzen et al., Phys. Rev. Lett. <b>124</b>, 076601 (2020)] which allows for NEGF simulations with time linear scaling, however, at the cost of large memory consumption. The reason is the need to store the two-particle correlation function. This problem can be overcome for a number of approximations by reformulating the kinetic equations in terms of fluctuations – an approach that was developed, for classical systems, by Yu.L. Klimontovich [JETP <b>33</b>, 982 (1957)]. Here, we present an overview of his ideas and extend them to quantum systems. In particular, we demonstrate that this quantum fluctuations approach can reproduce the nonequilibrium <i>GW</i> approximation [E. Schroedter <i>et al</i>., Cond. Matt. Phys. <b>25</b>, 23401 (2022)] promising high accuracy at low computational cost which arises from an effective semiclassical stochastic sampling procedure. We also demonstrate how to extend the approach to the two-time exchange-correlation functions and the density response properties. [E. Schroedter <i>et al</i>., Phys. Rev. B <b>108</b>, 205109 (2023)]. The results are equivalent to the Bethe–Salpeter equation for the two-time exchange-correlation function when the generalized Kadanoff-Baym ansatz with Hartree-Fock propagators is applied [E. Schroedter and M. Bonitz, phys. stat. sol.

Forced excitation is resonant if speed of an exciter coincides with the eigen speed of excited wave but may give rise to the excited perturbations with the speed different from the eigen one.

The dependence of the excited radial electric field and azimuthal magnetic field on axial and radial parameters of the plasmas lab, as well as on the slab thickness and laser pulse width size, is investigated.

Rectangular-triangular, super-Gaussian, and sinusoidal lasers exhibit a significantly steeper radial gradient of ponderomotive potential in comparison with other laser profiles, and excite intense radial electric fields and generate azimuthal magnetic fields in plasma slab.

In this work, Ci-Liu-Ti (CLT), an MHD code in the three-dimensional toroidal geometry, is applied for the linear simulation of the ideal pedestal MHD instabilities. The simulations are performed for the experimental advanced superconducting tokamak-like elongated divertor configuration with large triangularity, which is generated by the high-accuracy free-boundary equilibrium solver (CLT-EQuilibrium, i.e., CLT-EQ) developed recently. The present work focuses on the influence of the magnetic shear, which is scanned by adjusting the pedestal current with a fixed pedestal pressure profile. As the pedestal current increases, both the local (<i>S</i>_local) and global (<i>S</i>_global) magnetic shear decrease. The ballooning mode is destabilized along with the decrease of <i>S</i>_local, and stabilized when <i>S</i>_local is negative for the whole region of bad curvature, which implies the access of the second stable region. Further increase of the pedestal current leads to the destabilization of the kink mode, which is stabilized again until <i>S</i>_global is negative at the location of significant gradient of current density.
