Fractional Fermi Sea: Physicists Discover a New Phase of Matter Beyond Established Theory

Scientists have engineered a never-before-seen quantum state, uncovering a new phase of matter with hidden order beyond conventional theory. Researchers have shown that an unusual quantum state known as a “fractional Fermi sea” can be deliberately created, opening the door to a previously unknown phase of matter. The work, published in Physical Review Letters, was [...]
