Two-photon absorption pumping (TPA-induced pumping) is responsible for significant and rapid gain and phase shifts within the semiconductor optical amplifier (CRSOA) carrier reservoir. Recent research by Amer Kotb and Li Wei, both from the Changchun Institute...

Nanoscopy refers to the ability of seeing beyond the optical limit of 200-300nm. The super-resolution technique of nanoscopy is stimulated emission depletion microscopy (STED), which was developed by Jan Wichmann and Stefan W. Hell in 1994. It was experimentally...

Because of its huge Rashba effect, germanium telluride makes a great candidate for functional spintronic devices. HZB scientists have now discovered an intriguing phenomenon in GeTe. They studied the electronic response of samples to thermal excitation. Surprised,...

You can restore the original state by switching a bit of memory on a computer. Only two states can be called "0" and "1". TU Wien (Vienna), however, has discovered an incredible effect: An atomic switch that must be switched back and forth twice to reach...

CERN announced that the world's strongest particle accelerator will begin delivering proton collisions for experiments at an unprecedented energy level. The Large Hadron Collider will soon be able to provide data at an unprecedented energy of 13.6 TeV....

On July 4, 2012, the ATLAS/CMS collaborations at Large Hadron Collider, (LHC), announced the discovery by a new particle that had features similar to those predicted for the Higgs boson in the Standard Model particle physics. This discovery was a significant...

The Large Hadron Collider, ten years after discovering the Higgs boson in the Higgs boson's discovery, is about to begin smashing protons at unprecedented energy levels as part of its quest for more information about the universe. After a three-year...

Today marks ten years since the announcement of the Higgs Boson's discovery. The international ATLAS and CMS collaborations at Large Hadron Colliders (LHC), have published the results of their most extensive studies to date of the unique particle's...

The U.S. National Science Foundation (GACR) and Czech Science Foundation (USNSF) have joined forces to create a new collaborative project that aims to demonstrate efficient generation of dense Gamma-ray beams. Because of their extreme energies, pulsars and...

Scientists discovered a new kind of behavior in magnetic materials when they are heated up. When the temperature rises, magnetic spins freeze into a static pattern. This is a phenomenon that usually occurs when the temperature drops. Their findings were published...

A team of researchers from Florida State University has created a model to predict the spread of vortices within superfluids. This work provides new insights into the physics behind turbulence in superfluid systems like superfluid neutron star. The researchers...

This week in history, ten years ago, two international groups of scientists from different countries, including large numbers from Caltech, announced that they had discovered conclusive evidence of the Higgs boson. It is an elusive elementary particle that...

In May 2022, the Vertex Locator (VELO), was installed at LHCb to mark the end of 15 years worth of construction and development. With its millions of microscopic micropixels measuring 55 x 55 millimeters each, the pixel detector can reconstruct particles'...

Popular culture is full of time travel stories, including many that are told through television, movies and literature. It is an old idea, however. One could argue that Oedipus Rex, a Greek tragedy written over 2,500 years ago by Sophocles, is the first time...

Quantum physicists are fascinated by the behavior of electrons. Recent innovations in instruments, sources, and facilities have allowed researchers to access more information in quantum materials. However, these research innovations are producing unprecedented--and...

As the circles move across one another, watch out for patterns. These patterns are created by two sets obliquely offset from one another and are known as moire (pronounced mwara-AY). Moire patterns are optical illusions that create neat simulations for movement....

Researchers have been able to track the first fraction of a second after sunlight strikes solar cells. This gives them insight into how they generate electricity. Researchers could improve solar cells by probing the first moments of light conversion into...

Many quantum many-body physics researchers are not able to reach exact conclusions or solutions, especially in more than one dimension. This holds true also for the Fermi Polaron problem. It describes instances where the many-body quantum background is not...

Structural color offers advantages over traditional color dyes. It has high resolution and good stability. This allows for full-tone modulation in visible light. To replace plasmonic metasurfaces that have higher losses, all-dielectric metasurfaces are being...

Researchers at the National University of Singapore have shown that Landau levels in different valleys of a two-dimensional (2D), valleytronic material, monolayertungsten diselenide, (WSe2) can be aligned at critical magnetic fields. In many areas of engineering...

There are many theories that attempt to explain the particular advantages of perovskite solar cells. For example, polarons and a huge Rashba effect are believed to play a significant role. These hypotheses have been disproven experimentally by the BESSY II...

Recent experiments published in Nature challenge our understanding of electron behavior in quantum materials. Researchers have used stacked layers of tungsten ditelluride to observe electrons behave in two dimensions as though they were in one dimension....

Topological photonics, a rapidly developing area of research, focuses on designing photonic lattices whose light behavior is inspired by the topological insulators. Although most of the research in this area focused on photonic systems with linear topological...

Boston College physicists led an inter-disciplinary team that discovered a new particle or previously undetectable quantum exccitation. This is known as the axial Higgs mod, which is a magnetic relative to the mass-defining Higgs Boson particle. The team...
