A magnetic octupole and the three decreasing intensity peaks are predicted to be present in inelastic neutron scattering for π-flux QSI. Credit: Desrochers & Kim Quantum spin liquids are fascinating quantum systems that have recently attracted significant research attention. These systems are characterized by a strong competition between interactions, which prevents the establishment of a […]
A high-level schematic of the photonic integrated chip, developed by the Gaeta lab, for all-optical optical frequency division, or OFD—a method of converting a high-frequency signal to a lower frequency. Credit: Yun Zhao/Columbia Engineering In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave […]
March 19, 2024 — STMicroelectronics announces expansion of its STPOWER MDmesh DM9 AG family with automotive-grade 600V/650V superjunction MOSFETs, delivering superior efficiency and durability for on-board charger (OBC) and DC/DC converter applications in hard-switching and soft-switching topologies . With outstanding RDS(on) per die area and minimal gate charge, the silicon-based devices combine low energy losses with […]
Top: In the new comb system, two pump lasers shape each tooth, producing a frequency comb that could theoretically be sharper than a comb produced by a single laser. Bottom: The interaction between the two lasers randomly produces solitons in two different phases, which can be understood as a soliton pulse having either a positive […]
Here, in our series on the latest EW BrightSparks of 2023, we highlight Ifaz Uddin, a student at Imperial College London (ICL), studying Joint Maths and Computer Science. Achievements Since coming to the UK over seven years ago, Ifaz has faced several difficulties, which – with determination and spirit – he has worked to overcome […]
In 1H23, revenues rose 43.3% compared to the first half of 2022, driven by vendors shipping backlogged products. In 2H23, revenues declined 16.6% compared to the same period a year earlier. Adoption of Wi-Fi 6E, which expands Wi-Fi’s use to include the 6 GHz band of spectrum, continued to grow in 4Q23. Within the enterprise […]
March 13, 2024 — STMicroelectronics recently released automotive-grade 600V/650V super-junction MOSFETs in the STPOWER MDmesh DM9 AG series, delivering superior efficiency and durability for on-board charger (OBC) and DC/DC converter applications in hard-switching and soft-switching topologies. With outstanding RDS(on) per die area and minimal gate charge, the silicon-based devices combine low energy losses with outstanding switching […]
March 12, 2024 — According to a report from the Korean Customs Service, South Korea’s exports in the first 10 days of March 2024 decreased by 13.4% year-on-year to US$13.54 billion, of which semiconductor exports increased by 21.7% year-on-year. In addition, the Korean industry said that equipment investment increased by 4.1% year-on-year in January this […]
Electrons whizzing through the kagome metal Fe3Sn2 are influenced by the proximity of a flat band (shown by the reflection of the top ball on a flat surface). This causes the electronic charge to be fractionalized or split (shown here by the appearance of the lower ball). Researchers have now observed this effect spectroscopically. Credit: […]
