Para peneliti di Finlandia telah mengukur sinyal energi yang lebih kecil dari satu zeptojoule menggunakan kalorimeter baru. Pencapaian ini membuka jalan bagi pengembangan komputasi kuantum dan pencarian materi gelap yang lebih baik.

Profesor Akademi Mikko Möttönen memimpin tim di Universitas Aalto, bekerja sama dengan IQM dan Pusat Penelitian Teknis Finlandia. Mereka membuat perangkat tersebut dari logam superkonduktor dan konduktor normal yang merespons perubahan suhu sekecil apa pun. Sensor tersebut mencatat pulsa elektromagnetik sebesar 0,83 zeptojoule setelah penyaringan cermat terhadap sinyal gelombang mikro. Menurut para peneliti, ini menandai pengukuran kalorimetri pertama dengan sensitivitas tersebut.

Physicists at MIT have developed a new microscope using terahertz light to directly observe hidden quantum vibrations inside a superconducting material for the first time. The device compresses terahertz light to overcome its wavelength limitations, revealing frictionless electron flows in BSCCO. This breakthrough could advance understanding of superconductivity and terahertz-based communications.

Physicists revive 1773 experiment to hunt dark matter

Researchers propose updating a 1773 experiment by Henry Cavendish to detect millicharged particles, a potential dark matter candidate. The design uses nested metal shells and could be 10,000 times more sensitive than past methods. The setup promises to be cheaper and faster than particle accelerators.

Scientists unveil camera capturing trillionth-of-a-second events

Selasa, 21 April 2026 Dilaporkan oleh AI

Researchers at East China Normal University have developed a new imaging technique that captures ultrafast events in trillionths of a second, revealing both brightness and structural changes in a single shot. The method, called compressed spectral-temporal coherent modulation femtosecond imaging (CST-CMFI), tracks phenomena like plasma formation and electron movement. Yunhua Yao, the team leader, described it as a major advance for physics, chemistry, and materials science.
