Researchers from Monash University have unlocked fresh insights into the behavior of quantum impurities within materials.

The new, international theoretical study introduces a novel approach known as the “quantum virial expansion,” offering a powerful tool to uncover the complex quantum interactions in two-dimensional semiconductors.

This breakthrough holds potential to reshape our understanding of complex quantum systems and unlock exciting future applications utilizing novel 2D materials.

Scientists successfully filmed sound waves in a diamond crystal structure for the first time ever using an X-ray free-electron laser (XFEL).

Conservation laws are central to our understanding of the universe, and now scientists have expanded our understanding of these laws in quantum mechanics.

A conservation law in physics describes the preservation of certain quantities or properties in isolated physical systems over time, such as mass-energy, momentum, and electric charge.

Conservation laws are fundamental to our understanding of the universe because they define the processes that can or cannot occur in nature. For example, the conservation of momentum reveals that within a closed system, the sum of all momenta remains unchanged before and after an event, such as a collision.

Engineers at Aalto University have developed an improved method for long-distance wireless charging. By enhancing the interaction between transmitting and receiving antennas and leveraging the “radiation suppression” phenomenon, they’ve deepened our theoretical understanding of wireless power transfer beyond the traditional inductive methods, a significant advancement in the field.

Charging over short distances, such as through induction pads, uses magnetic near fields to transfer power with high efficiency, but at longer distances the efficiency dramatically drops. New research shows that this high efficiency can be sustained over long distances by suppressing the radiation resistance of the loop antennas that are sending and receiving power.

Researchers from Tokyo Metropolitan University have engineered a range of new single-walled transition metal dichalcogenide (TMD) nanotubes with different compositions, chirality, and diameters by templating off boron-nitride nanotubes. They also realized ultra-thin nanotubes grown inside the template, and successfully tailored compositions to create a family of new nanotubes. The ability to synthesize a diverse range of structures offers unique insights into their growth mechanism and novel optical properties.

The work is published in the journal Advanced Materials.

The carbon nanotube is a wonder of nanotechnology. Made by rolling up an atomically thin sheet of carbon atoms, it has exceptional mechanical strength and electrical conductivity among a range of other exotic optoelectronic properties, with potential applications in semiconductors beyond the silicon age.

Karin’s life took a dramatic turn when a farming accident claimed her right arm more than 20 years ago. Since then, she has endured excruciating phantom limb pain. “It felt like I constantly had my hand in a meat grinder, which created a high level of stress and I had to take high doses of various painkillers.”

In addition to her intractable pain, she found that conventional prostheses were uncomfortable and unreliable, and thus of little help in daily life. All this changed when she received groundbreaking bionic technology that allowed her to wear a much more functional prosthesis comfortably all day. The higher integration between the bionics and Karin’s residual limb also relieved her pain. “For me, this research has meant a lot, as it has given me a better life.”

Mechanical attachment and reliable control are two of the biggest challenges in artificial limb replacement. People with limb loss often reject even the sophisticated prostheses commercially available due to these reasons, after experiencing painful and uncomfortable attachment with limited and unreliable controllability.

The idea of the multiverse has at least two conceptually distinct sources in theoretical physics: quantum mechanics and cosmology. The many worlds of quantum mechanics are very different in terms of their nature and origin from cosmology’s multiverse. However, physicists have reason to believe that ultimately, these two distinct multiverses are in fact one and the same, writes David Wallace.

In big budget science-fiction and fantasy franchises, the “multiverse” is a collection of universes – some quite like our own, some differing from ours only in the way some historical event played out or some person’s life unfolded, some vastly different and filled with strange wonders. But in the drier and more disciplined world of modern physics, “multiverse” means… well, pretty much the same, only without the prospect of easily moving from one universe to the next. The multiverse of physics is revealed more subtly, by hints hidden in our observations and our theories.

Or rather: the multiverses of physics are revealed more subtly. For remarkably, physics gives us not one but three different multiverses, and reasons to accept all three.

A research group at the Institute for Molecular Science has successfully observed the left and right handedness of material structures at the nanoscale, by illuminating chiral gold nanostructures with circularly polarized light and detecting the optical force acting on a probe near the nanostructures. This result demonstrated that it is possible to analyze the chiral structure of matter at the nanoscale using light.

Chirality describes the property of a material structure not being superimposable onto its mirror image. Since the left and right hands, which are mirror images of each other, do not coincide (they are not the same), they are chiral.

Chiral objects can be distinguished to right-or left-handedness. Many substances that constitute life are chiral, and often only one of either the right-or left-handedness naturally exists. Also, in new functional materials, their chiral nature often plays an important role for the functions.

This week, researchers proved empirically that life isn’t fair. Also, you’ll notice that, in a superhuman display of restraint, I managed to write a paragraph about the simulated universe hypothesis without once referencing “The Matrix.” (Except for this reference.)

Oh, so a European research team has proven that flipped coins aren’t actually fair? Buddy, life isn’t fair! Do you think the world owes you two equally probable outcomes as established by an axiomatic mathematical formalization? When I was a kid, we didn’t even have coins! We had to roll dice! It took 10 minutes to start a football game! Oh, so a coin is very slightly more likely to land on the same face as its initial position? Quit crying! It’s only a meaningful bias if you flip a coin multiple times!

Applying a recently discovered physical law, a physicist at the University of Portsmouth has contributed to the discussion about whether or not the universe is a simulation. The simulated universe hypothesis proposes that the universe is actually a simulation running on a vastly complex computing substrate and we’re therefore all just NPCs, walking through our animation loops and saying, “Hail, summoner! Conjure me up a warm bed!” and “Do you get to the Cloud District often?”
