Long-range attractive interactions between dark matter particles can significantly enhance their annihilation, particularly at low velocities. This ``Sommerfeld enhancement'' is typically computed by evaluating the deformation of the two-particle wav

This evocative narrative weaves together medical insights, psychological analyses, philosophical musings, and spiritual reflections to explore the theme of love: the core and essence of our very being, the perpetual yearning of our deepest true self.

We construct a new surgery type operation by switching between two exact fillings of Legendrians which we call a BSP surgery. In certain cases, this surgery can preserve monotonicity of Lagrangians. We prove a wall-crossing type formula for the chang

Enjoy Sommerfeld trilogy of three Mennonite romances by bestselling author Kim Vogel Sawyer all under one value-priced cover. Amidst a quiet Kansas Mennonite community three women seek a place to belong. Marie is returning to reunite with her family.
The development of good thermoelectric materials exhibiting high $ZT$ (=$\frac{PF}{\kappa} T$) requires maximizing power factor, $PF$, mainly governed by electrons, and minimizing thermal conductivity, $\kappa$, associated not only with electrons but

We revisit the well known Bohr-Sommerfeld quantization rule (BS) of order 2 for a self-adjoint 1-D $h$-Pseudo-differential operator within the algebraic and microlocal framework of Helffer and Sj\"ostrand

It is shown that for carbon monosulfide ${\rm C}\,{\rm S}$ in the Born-Oppenheimer formalism, by taking into account the RKR turning points found by Coxon and Hajigeorgiou (2023), and asymptotics at small and large internuclear distances, the potenti

We present a formalism to describe the motion of a fluid that is fully covariant with respect to arbitrary observers. To achieve full covariance, we write prognostic equations for quantities that belong to the graded exterior algebra of the cotangent

We show that the relic density of asymmetric dark matter with long-range interactions is affected by the Sommerfeld enhancement. The annihilation cross section of asymmetric dark matter is enhanced due to the Sommerfeld effect. It results the relic d
