Physicists observationally confirm Hawking's black hole theorem for the first time

There are certain rules that even the most extreme objects in the universe must obey. A central law for black holes predicts that the area of their event horizons—the boundary beyond which nothing can ever escape—should never shrink. This law is Hawking's area theorem, named after physicist Stephen Hawking, who derived the theorem in 1971.

Taking cues from nature, breakthrough 'cellular fluidics' technology could have sweeping impacts

Inspired by the way plants absorb and distribute water and nutrients, Lawrence Livermore National Laboratory (LLNL) researchers have developed a groundbreaking method for transporting liquids and gases using 3D-printed lattice design and capillary action phenomena.

The first commercially scalable integrated laser and microcomb on a single chip

Fifteen years ago, UC Santa Barbara electrical and materials professor John Bowers pioneered a method for integrating a laser onto a silicon wafer. The technology has since been widely deployed in combination with other silicon photonics devices to replace the copper-wire interconnects that formerly linked servers at data centers, dramatically increasing energy efficiency—an important endeavor at a time when data traffic is growing by roughly 25% per year.

New algorithms give digital images more realistic color

If you've ever tried to capture a sunset with your smartphone, you know that the colors don't always match what you see in real life. Researchers are coming closer to solving this problem with a new set of algorithms that make it possible to record and display color in digital images in a much more realistic fashion.

Deep Space Atomic Clock moves toward increased spacecraft autonomy

Spacecraft that venture beyond our Moon rely on communication with ground stations on Earth to figure out where they are and where they're going. NASA's Deep Space Atomic Clock is working toward giving those far-flung explorers more autonomy when navigating. In a new paper published today in the journal Nature, the mission reports progress in their work to improve the ability of space-based atomic clocks to measure time consistently over long periods.

Physicists identify energy states of individual atoms following a collision

Physicists at Technische Universit├Ąt Kaiserslautern in the team of Professor Dr. Herwig Ott have succeeded for the first time in directly observing collisions between highly excited atoms, so-called Rydberg atoms, and atoms in the ground state. Particularly interesting is that they can precisely identify the energy states of the individual atoms, which was impossible until now. The researchers have developed a custom microscope for this purpose, with which they were able to directly measure the momenta of the atoms. The processes observed are important for understanding interstellar plasma and ultracold plasmas generated in the laboratory. The study was published in the renowned journal Nature Communications.

A crystal made of electrons

Researchers at ETH Zurich have succeeded in observing a crystal that consists only of electrons. Such Wigner crystals were already predicted almost ninety years ago but could only now be observed directly in a semiconductor material.

Scientists advance the understanding of potential topological quantum bits

Quantum computers promise great advances in many fields—from cryptography to the simulation of protein folding. Yet, which physical system works best to build the underlying quantum bits is still an open question. Unlike regular bits in your computer, these so-called qubits cannot only take the values 0 and 1, but also mixtures of the two. While this potentially makes them very useful, they also become very unstable.

Unlocking the potential of scanning near-field infrared microscopy

In NPL's Quantum Materials and Sensors group, we study the nanoscale properties of emerging quantum materials, including graphene, photonic metamaterials, and topological insulators. Recently the pioneering nature of our research was recognized with an invitation to write a short article for the journal Nature Reviews Physics. The Tools of the Trade article format is specifically targeted towards early-career researchers, so it was a great opportunity for me as I approach the end of my Ph.D.

Non-stop signal achieved in high-power Erbium-doped mid-infrared lasers

Decoding electron dynamics

Electron motion in atoms and molecules is of fundamental importance to many physical, biological and chemical processes. Exploring electron dynamics within atoms and molecules is essential for understanding and manipulating these phenomena. Pump-probe spectroscopy is the conventional technique. The 1999 Nobel Prize in Chemistry provides a well-known example wherein femtosecond pumped laser pulses served to probe the atomic motion involved in chemical reactions. However, because the timescale of electron motion within atoms and molecules is on the order of attoseconds (10-18 seconds) rather than femtoseconds (10-15 seconds), attosecond pulses are required to probe electron motion. With the development of the attosecond technology, lasers with pulse durations shorter than 100 attoseconds have become available, providing opportunities for probing and manipulating electron dynamics in atoms and molecules.

New ternary hydrides of lanthanum and yttrium join the ranks of high-temperature superconductors

A team led by Skoltech professor Artem R.

The research was published in the journal Materials Today.

Beam steering angle expander with two liquid crystal polymeric diffractive optical elements

Potential applications include autonomous vehicles and eye-tracking for virtual reality displays.
