At the very smallest scales, our intuitive view of reality no longer applies. It’s almost as if physics is fundamentally indecisive, a truth that gets harder to ignore as we zoom in on the particles that pixelate our Univerrse.

In order to better understand it, physicists had to devise an entirely new framework to place it in, one based on probability over certainty. This is quantum theory, and it describes all sorts of phenomena, from entanglement to superposition.

Yet in spite of a century of experiments showing just how useful quantum theory is at explaining what we see, it’s hard to shake our ‘classical’ view of the Universe’s building blocks as reliable fixtures in time and space. Even Einstein was forced to ask his fellow physicist, “Do you really believe the Moon is not there when you are not looking at it?”

In the world of physics, the idea of particles moving faster than light has always been a bit of a wild card. These particles, known as tachyons, have stirred up debates and skepticism.

However, a recent study published in Physical Review D has shaken up our understanding of these enigmatic particles.

For a long time, tachyons were considered more of a theoretical oddity than a scientific possibility. They seemed to conflict with the special theory of relativity, which has been a cornerstone of modern physics.

Particle accelerators are pricey, but their cost comes with good reason: These one-of-a-kind, state-of-the-art machines are intricately designed and constructed to help us solve mysteries about what makes up our universe. Still, the scientists and engineers building these machines must do their best to save where they can. Researchers at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility are supporting this mission by figuring out how to optimize cavities, one of the most critical parts of an accelerator.

New research confirms the Standard Model’s predictions about the Higgs boson while suggesting future data may reveal unknown aspects of particle physics.

The Higgs boson was discovered in the detectors of the Large Hadron Collider a dozen or so years ago. It has proved to be a particle so difficult to produce and observe that, despite the passage of time, its properties are still not known with satisfactory accuracy. Now we know a little more about its origin, thanks to the just-published achievement of an international group of theoretical physicists with the participation of the Institute of Nuclear Physics of the Polish Academy of Sciences.

Scientists discover that interplanetary shocks that strike Earth’s magnetic field head-on cause more powerful ground-level electric currents, threatening pipelines and submarine cables.

Auroras are caused by particles from the sun hitting the Earth’s magnetic field — but these impacts also cause geomagnetically induced currents at ground level, which can damage infrastructure that conducts electricity. Scientists studying these currents to protect critical infrastructure have carried out the first research which compares interplanetary shocks to real-time measurements of geomagnetically induced currents, showing that the angle of the shocks’ impact is key for forecasting possible damage to infrastructure: shocks that hit the magnetic field at an angle produce less powerful currents.

The impact of interplanetary shocks on infrastructure.

In a study published recently in Physical Review Letters, researchers unveiled a new type of quantum sensor that they report leverages quantum entanglement to perform detections that, note the quote marks, “travel back in time”. The researchers add the findings could — one day — lead to novel quantum sensors that are ideally suited for astronomical detection and magnetic field investigations.

The study, led by Kater Murch, Charles M. Hohenberg Professor of Physics and Director of the Center for Quantum Leaps at Washington University in St. Louis, introduces a sensor that can probe past events in complex systems. The team, which also included scientists from the National Institute of Standards and Technology (NIST) and the University of Cambridge, described the innovation in the press release as a bit like “sending a telescope back in time to capture a shooting star that you saw out of the corner of your eye.”

The sensor operates by entangling two quantum particles in a quantum singlet state, where their spins point in opposite directions. The process begins with one particle, the “probe,” being subjected to a magnetic field that causes it to rotate. The key breakthrough comes when the second particle, the “ancilla,” is measured. This measurement effectively sends its quantum state back in time to the probe, allowing researchers to optimally set the spin direction of the probe qubit in what Murch refers to as hindsight.

Physicists in Konstanz (Germany) have discovered a way to imprint a previously unseen geometrical form of chirality onto electrons. The electrons are shaped into chiral coils of mass and charge. Such engineered elementary particles may open new research avenues in fundamental physics and electron microscopy.

Have you ever placed the palm of your left hand on the back of your right hand, in such a way that all fingers point in the same direction? If you have, then you probably know that your left thumb will not touch its right counterpart. Neither rotations nor translations nor their combinations can turn a left hand into a right hand and vice versa. This feature is called chirality.

Scientists at the University of Konstanz have now succeeded to imprint such a three-dimensional chirality onto the wave function of a single electron. They used laser light to shape the electron’s matter wave into left-handed or right-handed coils of mass and charge. Such engineered elementary particles with chiral geometries other than their intrinsic spin have implications for fundamental physics but may also be useful for a range of applications, such as quantum optics, particle physics or electron microscopy.
