The experimental demonstration of topological dissipation in photonic resonators
So far, physicists have primarily studied topological phases in conservatively coupled systems. These are systems with dynamics that do not dissipate and a phase space that does not shrink over time. They are in stark contrast with dissipative system.....»»
Researchers reveal acoustic topological corner anomaly
Topological acoustics provides a new approach for manipulating acoustic waves using the novel wave transport phenomenon. In less than a decade, it has provided a series of promising new ideas for the directional control of acoustic field......»»
Lossless light: Revisiting Raman gain and amplification in a silicon photonic platform
Stars emit light that travels through empty space without significant attenuation. The visual signal is essentially lossless until detected. After many years and billions of kilometers, starlight-photons may eventually encounter the earth's atmospher.....»»
Efficient heat dissipation perovskite lasers using a high-thermal-conductivity diamond substrate
Perovskite lasers have rapidly achieved progress in developing continuous-wave excited lasing from a femtosecond pulse excited lasing, which is considered a critical step towards electrically excited lasing. After continuous-wave lasing at room tempe.....»»

Senegal harvests first experimental homegrown wheat
With the whir of a mower, under a clear blue sky, Senegalese researchers have begun harvesting a crop of experimental homegrown wheat, the latest step in a years-long effort to reduce reliance on imports......»»
Fully recyclable printed electronics ditch toxic chemicals for water
Engineers at Duke University have produced the world's first fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a.....»»
New satellite technology tested in the Schnalstal/Senales valley to measure thermal conductivity of snow
Over the past few days, a small Cessna aircraft carrying an experimental technology flew over the Senales Valley in South Tyrol between Vernago Lake and Grawand. Over the course of two flights, a sensor measured the heat exchange between snow and air.....»»
A new type of photonic time crystal gives light a boost
Researchers have developed a way to create photonic time crystals, and they have shown that these bizarre, artificial materials amplify the light that shines on them. These findings, described in a paper in Science Advances, could lead to more effici.....»»
Extraction of topological invariants from band structure in the synthetic frequency dimension
Over last few decades, study of topological phases of matter in solid-state electron systems has been extended to other research fields, including synthetic dimensions, and motivates extensive research on topological materials in many systems. Synthe.....»»
Imaging technique reveals electronic charges with single-atom resolution
Materials typically conduct electricity or insulate against it—so experimental and theoretical physicists have been captivated by a compound called samarium hexaboride (SmB6) that appears to do both. Numerous studies over the course of 50 years hav.....»»
Connecting distant silicon qubits for scaling up quantum computers
In a demonstration that promises to help scale up quantum computers based on tiny dots of silicon, RIKEN physicists have succeeded in connecting two qubits—the basic unit for quantum information—that are physically distant from one another......»»
