North Korea Claims Successfully Testing a New Hypersonic Gliding Warhead

Posted by in categories: energy, existential risks, military

These missiles are too fast to detect. Hypersonic weapons technology is at the heart of a new arms race. Currently, the US, China, and Russia are all competing to develop the most effective long-range hypersonic missiles. A recent report revealed that North Korea has also successfully tested a hypersonic missile on January 5, 2022, the country’s second reported test of a hypersonic missile.


North Korea has also referred to verifying the “fuel ampoule system” during this deployment which means that the liquid fuel used by the missile was sealed at production. This allows for rapid deployment even after the missile has been stored for long periods of time, while also reducing its vulnerability to pre-emptive strikes.

We have now seen what North Korea can do in quite imaginative ways.

Atomically crafted quantum magnets and their anomalous excitations

Posted by in categories: energy, nanotechnology, quantum physics

Quantum magnets can be studied using high-resolution spectroscopic studies to access magnetodynamic quantities including energy barriers, magnetic interactions, and lifetime of excited states. In a new report now published in Science Advances, Sascha Brinker and a team of scientists in advanced simulation and microstructure physics in Germany studied a previously unexplored flavor of low-energy spin excitation for quantum spins coupled to an electron bath. The team combined time-dependent and many-body perturbation theories and magnetic field-dependent tunneling spectra to identify magnetic states of the nanostructures and rationalized the results relative to ferromagnetic and antiferromagnetic interactions. The atomically crafted nanomagnets are appealing to explore electrically pumped spin systems.

Anomalous magnetodynamics

Magnetodynamics at the atomic scale form the cornerstone of spin-based nanoscale devices with applications in future information technologies. Interactions of local spin states also play a crucial role with the local environment to determine their properties. Researchers have described the impact of orbital hybridization effects, charge transfer, and the presence of nearby impurities as strong influencers on the magnetic ground state, to determine a range of magnetodynamic qualities, including magnetic anisotropy, spin lifetime and spin-relaxation mechanisms. Experimental methods can be developed to directly capture these properties and analyze the magnetic phenomena of classical and semiclassical descriptions at sub-nanometer scales to reveal the emergence of exquisite quantum mechanical effects.

Pew Pew: The US Navy is Really Getting into Directed-Energy Weapons

Posted by in category: energy

It plays a significant role in our lives.

From enabling us to walk around and not bump into things to developing highly advanced directed energy weapons, the electromagnetic spectrum is vitally important to many aspects of our modern lives. But, life as we know it would also not be possible if electromagnetic radiation, notably visible light, did not exist.

For most of human history we have only known (but not fully understood) a very small portion of the spectrum — namely visible light and “heat” in the form of infrared light. But, since the scientific enlightenment our knowledge of the spectrum, and applications using it, have literally revolutionized the way we live and perceive the world and the cosmos around us.
