Compact Analytical Model for Real-Time Evaluation of OAM-Based Inter-Satellite Links
This paper presents an efficient analytical framework for evaluating the performance of inter-satellite communication systems utilizing orbital angular momentum (OAM) beams under pointing errors. An accurate analytical model is first developed to characterize intermodal crosstalk caused by beam misalignment in OAM-based inter-satellite links. Building upon this model, we derive efficient expressions to analyze and optimize system performance in terms of bit error rate (BER). Unlike traditional …

Cosmological bounds on dark matter annihilation using dark ages 21-cm signal
We investigate the impact of dark matter (DM) annihilation on the global 21-cm signal during the dark ages and cosmic dawn eras. The 21-cm line provides a complementary probe for studying the nature of dark matter beyond standard cosmological observables. In the standard $Λ$CDM framework, the expected absorption amplitude of the dark ages global 21-cm signal is approximately $-42\, \rm mK$. However, energy injection from DM annihilation can significantly heat and ionize the intergalactic mediu…

Dynamical friction and massive black hole orbits: analytical predictions and numerical solutions
We investigate the orbital decay of a massive BH embedded in a dark matter halo and a stellar bulge, using both analytical and numerical simulations with the aim of developing and validating a reliable dynamical friction (DF) correction across simulation resolutions. We develop a Python-based library to solve the equations of motion of the BH and provide an analytical framework for the numerical results. Then, we carry out simulations at different resolutions and for different softening choices…

Sphericity and Analyticity of a strictly pdeusoconvex hypersurface in low regularity I
In our earlier work \cite{KZ}, we introduced an analytic regularizability theory for smooth strictly pseudoconvex hypersurfaces in complex space. That is, we found a necessary and sufficient condition for a hypersurface to be CR-equivalent to an analytic target. The condition amount to the holomorphic extension property for a smooth function on a totally real submanifold, both the function and the submanifold being uniquely associated with the given hypersurface. In the present paper, we deve…

Nonadiabatic effect in high order harmonic generation revealed by a fully analytical method
We propose a fully analytical method for describing high-order harmonic generation (HHG). This method is based on the strong-field approximation (SFA) and utilizes the perturbation expansion method. Specifically, we expand the laser-induced dipole moment to third-order analytical expansion (TAE) and fifth-order expansion (FAE) with respect to the Keldysh parameter $γ$. The TAE method is suitable for $γ\leqslant0.27$, while the FAE method can be applied for $γ\leqslant 0.65$. We demonstrate t…
