Teori dawai muncul dari asumsi fisika dasar dalam studi baru

Para fisikawan telah menunjukkan bahwa tanda-tanda kunci dari teori dawai dapat muncul secara alami dari beberapa aturan sederhana mengenai perilaku partikel pada energi ekstrem. Para peneliti dari Caltech, New York University, dan sebuah institut di Barcelona mencapai hasil ini dengan menggunakan pendekatan bootstrap yang dimulai dengan asumsi minimal, alih-alih mengandaikan adanya dawai. Karya ini telah diterima untuk dipublikasikan di Physical Review Letters.

Tim peneliti memulai dengan dua kondisi tentang bagaimana partikel terhambur dalam tabrakan berenergi tinggi. Kondisi pertama mengharuskan probabilitas hamburan turun dengan cepat pada energi yang sangat tinggi, sebuah sifat yang dikenal sebagai ultrasoftness. Kondisi kedua menetapkan sesedikit mungkin titik di mana probabilitas tersebut mencapai nol. Dari batasan-batasan ini saja, matematika menghasilkan rangkaian massa dan spin partikel tak terhingga yang mendefinisikan spektrum dawai, beserta ciri khas lain dari teori tersebut.

Physicists with the STAR collaboration have observed particles emerging directly from empty space during high-energy proton collisions at Brookhaven National Laboratory. The experiment provides strong evidence that mass can arise from vacuum fluctuations, as predicted by quantum chromodynamics. Quark-antiquark pairs promoted to real particles retained spin correlations tracing back to the vacuum.

Physicists have created a simple model of the universe using ultracold atoms to explore whether time arises from quantum effects rather than existing independently. The work, led by researchers at the University of Birmingham, offers new experimental support for ideas that have circulated for decades.

An international team of physicists has found that quantum collapse models, potentially linked to gravity, introduce a minuscule uncertainty in time itself. This sets a fundamental limit on clock precision, though far below current detection levels. The research, published in Physical Review Research, explores ties between quantum mechanics and gravity.

Researchers at Tokyo University of Science have demonstrated matter-wave diffraction in positronium, an exotic atom formed by an electron and its antimatter counterpart, a positron. This marks the first observation of quantum interference in such a system. The findings, published in Nature Communications, confirm positronium's wave-particle duality.

Researchers at the University of Colorado Boulder have developed a material made from staple-shaped particles that can switch between being strong and flexible or falling apart on command.

New research reinterprets the Einstein-Rosen bridge as a connection between two directions of time rather than a spatial shortcut. The study suggests this view could resolve the black hole information paradox and point to a universe that existed before the Big Bang. It was published in the journal Classical and Quantum Gravity.
