High throughput characterization method of electrical and phonon properties by dielectric resonant spectroscopy

Materials Genome Engineering Advances, EarlyView.
In conventional theories, electron‐phonon relaxation time τe‐p ${\tau }_{e\mbox{-}p}$—the average interval between two consecutive electron‐phonon collisions—is assumed to be independent of electron density. In this study, we establish a new relationship of τe−p=C∗·T−1·n−1/3 ${\tau }_{e-p}={C}^{\ast }\mathit{\cdot }{T}^{-1}\mathit{\cdot }{n}^{-1/3 ...

The formation of planetary disks and winds: an ultraviolet view

, 2008
Planetary systems are angular momentum reservoirs generated during star formation. This accretion process produces very powerful engines able to drive the optical jets and the molecular outflows.

Study of shock waves and related phenomena motivated by astrophysics

, 2016
This paper discusses the recent research in High-Energy-Density Physics at our Center. Our work in complex hydrodynamics is now focused on mode coupling in the Richtmyer- Meshkov process and on the supersonic Kelvin-Helmholtz instability. These processes

Two Micron‐Size Dark Dimensions

Fortschritte der Physik, EarlyView.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Probing the close environment of young stellar objects with interferometry

, 2003
The study of Young Stellar Objects (YSOs) is one of the most exciting topics that can be undertaken by long baseline optical interferometry. The magnitudes of these objects are at the edge of capabilities of current optical interferometers, limiting the ...

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

Fortschritte der Physik, EarlyView.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...
