Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters and transforms inside real-world materials has long been treated as a black ...

Weyl semimetals, a class of quantum materials defined by their unique band structure, host emergent chiral Weyl fermions that exhibit distinct physical properties. These materials hold great potential ...

HOUSTON – (June 17, 2025) – Vacuum is often thought of as empty, but in fact it is teeming with fleeting energy fluctuations — virtual photons popping in and out of existence that can interact with ...

Researchers at Stanford University have demonstrated a nanoscale optical device that entangles the spin of photons and electrons at room temperature, overcoming a major practical limitation in quantum ...
