Nonlinear Spectroscopy of Alkali Atoms in Cold Medium of Astrophysical Relevance
Atoms, 2017 The time-dependent population dynamics of hyperfine (HF) sublevels of n 2 p 3 / 2 atomic states upon laser excitation in a cold medium of alkali atoms is examined.

Testing Noncommutativity-Like Model as a Galactic Density Profile
Galaxies, 2021 Noncommutative-like model (NC-like) is an interesting alternative inspired by string theory to understand and describe the velocity rotation curves of galaxies without the inclusion of dark matter particles.

INTEGRAL and Nuclear Astrophysics [PDF]
, 2001 We briefly review the fundamentals of nuclear gamma-ray line astronomy (radioactive astronomy), focusing on its role to decipher the intimate physics of supernovae, either immediatly (via $^{56}Co)$ or after a time delay (via $^{44}Ti$).

Towards the first plasma-electron screening experiment
Frontiers in Physics, 2023 The enhancement of fusion reaction rates in a thermonuclear plasma by electron screening of the Coulomb barrier is an important plasma-nuclear effect that is present in stellar models but has not been experimentally observed.

Similarity Properties and Scaling Laws of Radiation Hydrodynamic Flows in Laboratory Astrophysics [PDF]
, 2011 The spectacular recent development of modern high-energy density laboratory facilities which concentrate more and more energy in millimetric volumes allows the astrophysical community to reproduce and to explore, in millimeter-scale targets and during ...

ANTARES and KM3NeT: The Latest Results of the Neutrino Telescopes in the Mediterranean
Universe, 2019 The measurement of cosmic neutrinos is a new and unique method to observe the Universe. Neutrinos are chargeless, weakly-interacting particles that can provide information about the interior of an astrophysical object for cosmological distances.

Advanced Science, EarlyView.Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

Astrophysical symmetries [PDF]
Proceedings of the National Academy of Sciences, 1996 Astrophysical objects, ranging from meteorites to the entire universe, can be classified into about a dozen characteristic morphologies, at least as seen by a blurry eye. Some patterns exist over an enormously wide range of distance scales, apparently as a result of similar underlying physics.

AIP Conference Proceedings, 1993 The problem of core-collapse supernovae is used to illustrate the many connections between nuclear astrophysics and the problems nuclear physicists study in terrestrial laboratories. Efforts to better understand the collapse and mantle ejection are also motivated by a variety of interdisciplinary issues in nuclear, particle, and astrophysics, including
