Layer-dependent magnetic phase diagram in Fe n GeTe2 (3 ≤ n ≤ 7) ultrathin films

Communications Physics, 2022
2D magnetism offers the prospect of ordered and controllable magnetic states at reduced dimensions and there is a desire to obtain materials which can realise these properties at room temperature.

Enhanced production of 60Fe in massive stars

Nature Communications
Massive stars are a major source of chemical elements in the cosmos, ejecting freshly produced nuclei through winds and core-collapse supernova explosions into the interstellar medium.

Parametric matrix models

Nature Communications
We present a general class of machine learning algorithms called parametric matrix models. In contrast with most existing machine learning models that imitate the biology of neurons, parametric matrix models use matrix equations that emulate physical ...

Abrupt structural transition in exotic molybdenum isotopes unveils an isospin-symmetric island of inversion

Nature Communications
Like electrons in atoms, protons and neutrons in nuclei occupy orbitals in a shell structure with energy gaps at magic numbers. Radioactive-beam experiments revealed the disappearance of magic numbers in some neutron-rich isotopes.

Theoretical model for the mechanical behavior of prestressed beams under torsion

Cogent Engineering, 2014
In this article, a global theoretical model previously developed and validated by the authors for reinforced concrete beams under torsion is reviewed and corrected in order to predict the global behavior of beams under torsion with uniform longitudinal ...

Coral Reef Carbonate Chemistry Variability at Different Functional Scales

Frontiers in Marine Science, 2018
There is a growing recognition for the need to understand how seawater carbonate chemistry over coral reef environments will change in a high-CO2 world to better assess the impacts of ocean acidification on these valuable ecosystems.

Luminosity Loss due to Beam Distortion and the Beam-Beam Instability [PDF]

Proceedings of the 2005 Particle Accelerator Conference, 2006
In a linear collider, sources of emittance dilution such as transverse wakefields or dispersive errors will couple the vertical phase space to the longitudinal position within the beam (the so-called ‘banana effect’). When the Intersection Point (IP) disruption parameter is large, these beam distortions will be amplified by a single bunch kink ...
