Quantum theory was originally formulated using complex numbers. Nonetheless, when replying to a letter by Hendrik Lorenz, Erwin Schrödinger (one of its founding fathers), wrote: "Using complex numbers in quantum theory is unpleasant and should be objected to. The wave...
Researchers at Korea Institute of Science and Technology (KIST) have recently tried to capture the interplay between different types of information that are important while collecting quantum measurements, namely information gain, disturbance and reversibility. Their...
Most energy-producing technologies used today are unsustainable, as they cause significant damage to our planet's natural environment. In recent years, scientists worldwide have thus been trying to devise alternative energy solutions that take advantage of abundant...
Physicists have predicted the existence of dark matter, a material that does not absorb, emit or reflect light, for decades. While there is now significant evidence hinting to the existence of dark matter in the universe, as it was never directed detected before its...
2D van der Waals crystals, a class of materials that exhibit strong in-plane covalent bonds and weak interlayer interactions, have recently become the focus of numerous research studies due to their plethora of unique electrical, optical, and mechanical properties....
While many studies have hinted at the existence of dark matter, a material that does not absorb, reflect or emit light, this elusive substance has not been directly observed so far. Over the past few decades, many teams worldwide have thus theorized about its possible...
In 2020, Prof. Teruo Ono and his colleagues at Kyoto University reported the very first observation of a magnetically controllable, superconducting diode effect in an artificial superlattice. Their findings, published in Nature, paved the way for other studies...
Fiber batteries are millimeter-thin batteries based on fibers that can be woven into items of clothing or used to create highly flexible, wearable electronics. In recent years, many research teams worldwide have been trying to fabricate these batteries, using a range...
Transistors based on semiconductor materials are widely used electronic components with many remarkable properties. For instance, they have a nonreciprocal electrical response, which means that they can isolate two parts of a circuit in such a way that one of the...
Moiré superlattices are systems in which two sheets of a material are placed on top of each other with a small angle misalignment, resulting in a characteristic pattern known as the Moiré pattern. In recent years, many physicists and material scientists have been...
